TECHNIQUES FOR ELECTRONIC AGGREGATION OF INFORMATION BACKGROUND [0001] A montage may comprise an aggregation of separate elements to form a single composite element. For instance, a montage may comprise a composite picture made up of several separate pictures, or a video sequence comprising a rapid sequence of disparate images. Electronic montage systems have been designed to create digital montages using digital content, such as a composite web page comprising different constituent web pages served from different web applications. Sometimes the constituent web pages are organized according to a central theme, such as a web pages related to a given search term used by a search engine, or web pages consistently visited by a user as stored in a browser history. Often, the constituent web pages are lower-fidelity representations of the actual web page due to space limitations of the composite web page. As such, a user may select a constituent web page to retrieve a higher-fidelity version of the selected web page for more in-depth viewing. As an amount of digital information increases, however, it becomes increasingly difficult to build a digital montage in a way that provides meaningful information to a user. It is with respect to these and other considerations that the present improvements have been needed. SUMMARY [0002] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter. [0003] Various embodiments are generally directed to electronic montage systems. Some embodiments are particularly directed to an electronic montage system arranged to generate a digital montage from heterogeneous data sources. The electronic montage system may allow a user to generate a customized digital montage with customized representations for a data source, thereby allowing other users to quickly identify and select a data source of interest for closer viewing. The electronic montage system may publish the customized digital montage to other users via a publishing model, a messaging model, or a combination of a publishing model and a messaging model. [0004] In one embodiment, for example, an apparatus may comprise a logic device arranged to execute a montage application. The logic device may comprise, for example, a processing system having a processor and memory. The montage application may comprise an authoring component operative to provide a presentation surface having multiple presentation tiles, receive control directives to associate content files with presentation tiles, generate tile objects for the content files based on content file types for the content files, and store the presentation surface and tile objects as a montage. The montage application may further comprise a presentation component operative to generate a first user interface view to present each tile object within each associated presentation tile of the presentation surface, receive a control directive to select a tile object, and generate a second user interface view to present a content file corresponding to the tile object. Other embodiments are described and claimed. [0005] These and other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive of aspects as claimed.

DETAILED DESCRIPTION [0020] Various embodiments are generally directed to electronic montage systems arranged to generate a digital montage from heterogeneous data sources. The electronic montage system may allow a user to generate a highly customized digital montage using content files generated by different software programs, such as application programs, for example. The digital montage may include one or more tile objects comprising customized representations for an underlying content file. A tile object may be constructed using information selectively extracted from a content file and formatted according to a type definition specifically built for the content file. The type definition includes detailed information about a content file, such as file extensions, data schemas, formatting controls, embedded objects, embedded code, properties, scripts, and other file specific information. The type definition also includes a set of rules concerning types of information to extract from a content file, formatting of the extracted information, a number of tile object versions to build, and so forth. In this manner, a wider range of content files may be used to author a digital montage, while constructing highly representative tile objects providing meaningful information for a viewer. This approach allows viewers to easily peruse the tile objects in a montage, identify a content file of interest among the many tile objects, and select a tile object to quickly retrieve the content file for closer viewing. As a result, the embodiments can improve affordability, scalability, modularity, extendibility, or interoperability for an operator, device or network. [0021] FIG. 1 illustrates a block diagram of a montage system 100 having a montage application 140. In one embodiment, for example, the montage system 100 and the montage application 140 may comprise various components, such as components 110, 130, for example. As used herein the terms "system" and "application" and "component" are intended to refer to a computer-related entity, comprising either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be implemented as a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical and/or magnetic storage medium), an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and/or thread of execution, and a component can be localized on one computer and/or distributed between two or more computers as desired for a given implementation. The embodiments are not limited in this context. [0022] In the illustrated embodiment shown in FIG. 1, the montage system 100 and the montage application 140 may be implemented by an electronic device. Examples of an electronic device may include without limitation a mobile device, a personal digital assistant, a mobile computing device, a smart phone, a cellular telephone, a handset, a one way pager, a two-way pager, a messaging device, a computer, a personal computer (PC), a desktop computer, a laptop computer, a notebook computer, a handheld computer, a tablet computer, a server, a server array or server farm, a web server, a network server, an Internet server, a work station, a mini-computer, a main frame computer, a supercomputer, a network appliance, a web appliance, a distributed computing system, a multiprocessor system, a processor-based system, a gaming device, consumer electronics, programmable consumer electronics, a television, a digital television, a set top box, a wireless access point, a base station, a subscriber station, a mobile subscriber center, a radio network controller, a router, a hub, a gateway, a bridge, a switch, a machine, or combination thereof. Although the montage application 140 as shown in FIG. 1 has a limited number of elements in a certain topology, it may be appreciated that the montage application 140 may include more or less elements in alternate topologies as desired for a given implementation. [0023] The components 110, 130 may be communicatively coupled via various types of communications media. The components 110, 130 may coordinate operations between each other. The coordination may involve the uni-directional or bi-directional exchange of information. For instance, the components 110, 130 may communicate information in the form of signals communicated over the communications media. The information can be implemented as signals allocated to various signal lines. In such allocations, each message is a signal. Further embodiments, however, may alternatively employ data messages. Such data messages may be sent across various connections. Exemplary connections include parallel interfaces, serial interfaces, and bus interfaces. [0024] In the illustrated embodiment shown in FIG. 1, the montage system may include one or more content files 104-c and the montage application 140. The content files 104-c may comprise digital content generated by a software program, such as an application program, a web application, a web service, and so forth. The montage application 140 may use one or more selected content files 104-c to generate a montage 120. In one embodiment, the one or more content files 104-c may be manually selected by a user. In one embodiment, the one or more content files 104-c may be automatically selected by a software program, such as by using search results related to a given search term used by a search engine, or content files 104-c consistently visited by a user as stored in a browser history. [0025] The montage application 140 may comprise, among other elements, an authoring component 110 and a presentation component 130. The authoring component 110 may be used by a user to author or produce a montage 120. A user authoring or producing a montage 120 may sometimes be referred to herein as a "content producer." The presentation component 130 may be used by a user to view or navigate a montage 120. A user viewing or navigating a montage 120 may sometimes be referred to herein as a "content consumer." The montage application 140 further includes other components as described in more detail with reference to FIGS. 2-11. [0026] The authoring component 110 may generally manage authoring operations for the montage application 140, including generating user interface views and tools to allow a content producer to generate, create or otherwise author a montage 120. A montage 120 may comprise a singular composite or aggregation of digital information elements from selected content files 104-c to form a single composite digital information element. A montage 120 may comprise, for example, a composite document having different constituent digital information elements generated by heterogeneous applications, such as applications files for application programs. Sometimes the constituent digital information elements are organized according to a central theme, such as those digital information elements relating to a business project, personal vacation, or a holiday. Often, the constituent digital information elements are lower-fidelity representations of the actual content files 104-c due to space limitations of the composite document. As such, a content consumer may select a constituent digital information element to retrieve a higher- fidelity version of the associated content file 104-c for more in-depth viewing. [0027] In one embodiment, for example, the authoring component 110 may be arranged to provide a presentation surface 122 for a montage 120. The presentation surface 122 may have multiple presentation tiles 124-a defined or disposed on the presentation surface 122 in a certain topology. The authoring component 110 may receive control directives 102-6 to associate certain content files 104-c with certain presentation tiles 124-a. The authoring component 110 may generate tile objects 126-e for the content files 104-c based on various content file types and type definitions associated with the content files 104-c. The authoring component 110 may store the presentation surface 122 and tile objects 126- e as part of a montage 120, which can then be published or distributed to various content consumers. [0028] It is worthy to note that "a" and "b" and "c" and similar designators as used herein are intended to be variables representing any positive integer. Thus, for example, if an implementation sets a value for a = 5, then a complete set of presentation tiles 124-a may include presentation tiles 124-1, 124-2, 124-3, 124-4 and 125-5. The embodiments are not limited in this context. [0029] The authoring component 110 may begin authoring operations to generate a montage 120 by providing a presentation surface 122 having multiple presentation tiles 124-a. A presentation surface 122 may comprise a two-dimensional (2D) or threedimensional (3D) topological space of any defined size having a coordinate system and boundaries. Examples for a presentation surface 122 may comprise a document for a word processing program, a slide for a presentation program, a worksheet for a spreadsheet program, a note for a note program, a contact card for a personal information manager (PIM), and other spaces typically used by application programs. [0030] A presentation tile 124-a may comprise a defined region of the presentation surface 122 designated for presenting a discrete set of information, such as a tile object 126-e. A defined region may be of any size, dimension or shape as desired for a given implementation. A given presentation surface 122 may have any number of presentation tiles 124-a, and each presentation tile 124-a may have a set of definitions (e.g., size, shape, dimension, geometry) to ensure that all the presentation tiles 124-a fit within a given size for a presentation surface 122. Definitions for presentation tiles 124-a may dynamically change based on a presentation surface 122, set of content files 104-c, associations between content files 104-c and a presentation tile 124-a, tile objects 126-e associated with content files 104-c, properties for a display, properties for a device, user preferences, and other factors. The embodiments are not limited in this context. [0031] In one embodiment, a content producer may custom define a presentation surface 122 and presentation tiles 124-a. A user interface for the montage application 140 may provide various controls specifically defined to modify characteristics of a presentation surface 122 and a set of presentation tiles 124-a on the presentation surface 122. Examples of such controls may include without limitation drawing controls, dimension controls, size controls, width controls, height controls, pixel controls, refresh controls, and so forth. Alternatively, a content producer may select from any number of montage templates providing different presentation surfaces and presentation tiles 124-a. [0032] The authoring component 110 may receive control directives 102-6 to associate certain content files 104-c with certain presentation tiles 124-a. The authoring component 110 may generate a user interface view and tools allowing a user to select a content file 104-a, and associate the content file 104-a with a presentation tile 124-a. For instance, a user may use an input device such as a pointing device to select a content file 104-1 and drag the content file 104-1 over a presentation tile 124-1. A user selection may generate a control directive 102-6 as a message or signal indicating the selection to the authoring component 110. Alternatively, control directives 120-& may be programmatically generated in accordance with a content selection algorithm. For instance, a content selection algorithm may have a set of defined rules to automatically select content files 104-c from results of a search generated by a search engine, or by analysis of user browsing patterns. The embodiments are not limited in this context. [0033] A content file 104-c may comprise any digital information element or digital content generated by a software program, such as an application program, a web application, a web service, a client application, a server application, a system program, and so forth. Different software programs may generate different types of digital content. As such, digital content generated by different software programs may comprise heterogeneous digital content. Examples for a content file 104-c may include without limitation application files, such as a word processing file, a spreadsheet file, a presentation file, a personal information manager (PIM) file, a database file, a publisher file, a drawing file, a note file, a message file, a project file, and so forth. Further examples for a content file 104-c may include multimedia files, such as an audio file, an image file, a video file, an audio/video (AV) file, an animation file, a game file, a markup file, a web page file, a social networking service (SNS) file, and so forth. It may be appreciated that these are merely a few examples of a content file 104-c, and embodiments are not limited to these examples. [0034] In one embodiment, a content file 104-c may comprise a content file for a productivity suite of inter-related client applications, server applications and web services, designed for a particular operating system, such as a MICROSOFT® OFFICE productivity suite for MICROSOFT WINDOWS®, made by Microsoft Corporation, Redmond, Washington. Examples for client applications may include without limitation MICROSOFT WORD, MICROSOFT EXCEL®, MICROSOFT POWERPOINT®, MICROSOFT OUTLOOK®, MICROSOFT ACCESS®, MICROSOFT INFOPATH®, MICROSOFT ONENOTE®, MICROSOFT PROJECT, MICROSOFT PUBLISHER, MICROSOFT SHAREPOINT® WORKSPACE, MICROSOFT VISIO®, MICROSOFT OFFICE INTERCONNECT, MICROSOFT OFFICE PICTURE MANAGER, MICROSOFT SHAREPOINT DESIGNER, and MICROSOFT LYNC. Examples for server applications may include without limitation MICROSOFT SHAREPOINT SERVER, MICROSOFT LYNC SERVER, MICROSOFT OFFICE FORMS SERVER, MICROSOFT OFFICE GROOVE® SERVER, MICROSOFT OFFICE PROJECT SERVER, MICROSOFT OFFICE PROJECT PORTFOLIO SERVER, and MICROSOFT OFFICE PERFORMANCEPOINT® SERVER. Examples for web services may include without limitation MICROSOFT WINDOWS LIVE®, MICROSOFT OFFICE WEB APPLICATIONS, MICROSOFT OFFICE LIVE, MICROSOFT LIVE MEETING, MICROSOFT OFFICE PRODUCT WEB SITE, MICROSOFT UPDATE SERVER, and MICROSOFT OFFICE 365. The embodiments are not limited to these examples. [0035] In one embodiment, a content file 104-c may comprise a content file personally authored by a same content producer of the montage application 140 to create a montage 120. For instance, assume a content producer is a project manager for a business project, and during the course of the business project, has authored various application files associated with the business project, such as a word processing file, a spreadsheet file, and a presentation file. The content producer may use the authoring component 110 of the montage application 140 to create an executive report having tile objects 126-e for each file personally authored by the content producer. [0036] The authoring component 110 may generate tile objects 126-e for selected content files 104-c based on various content file types for the content files 104-c. Once a content file 104-c has been associated with a presentation tile 124-a, the authoring component 110 may generate a tile object 126-e for the selected content file 104-c. In one embodiment, a single content file 104-c may be associated with a single presentation tile 124-a, thereby forming a one-to-one correspondence. In one embodiment, multiple content files 104-c may be associated with a single presentation tile 124-a, thereby forming a one-to-many correspondence. [0037] A tile object 126-e may comprise a representation, agent or "teaser" for a content file 104-c. A tile object 126-e is a concise set of information from an associated content file 104-c rendered in a way that allows a content consumer to quickly and easily determine whether an associated content file 104-c is of interest, and merits closer inspection of the associated content file 104-c. [0038] A tile object 126-e may be generated using a content portion \ 6-d retrieved from a content file 104-c. A content portion 6-d may comprise a subset of information derived or extracted from a complete set of information stored by a content file 104-c. One advantage of a montage 120 is that information from different content files 104-c may be presented on a single presentation surface 122. However, each content file 104-c may comprise a greater amount of information than can be presented within a defined region of a single presentation tile 124-a. For instance, if a content file 104-1 comprises a word processing document, the authoring component 110 may be unable to fit all the information (e.g., text, figures, images, drawings, embedded objects) contained within the word processing document within an available area or space of a presentation tile 124-1, even when miniaturized as a thumbnail. As such, the authoring component 110 may retrieve a subset of information from a set of information contained within the content source 104-1, format the subset of information to fit within a set of boundaries for the presentation tile 124-1, and store the formatted subset of information as a tile object 126-1. For example, the tile object 126-1 may comprise a combination of a title for the word processing document, a content producer (e.g., author) of the word processing document, and an image from the word processing document. [0039] A tile object 126-e may also include, or be associated with, a reference (e.g., an address, pointer or link) to a corresponding content file 104-c. When a tile object 126-e is selected by a user for closer inspection, the reference may be used to retrieve a corresponding content file 104-c to present a full-fidelity presentation of the content file 104-c. In one embodiment, the reference may be to the content file 104-c as stored in a local datastore. In this case, the reference may be used to retrieve the content file 104-c using peer-to-peer technology. In one embodiment, the reference may be to the content file 104-c stored in a remote datastore. In this case, the reference may be used to retrieve the content file 104-c using network storage and access technology. [0040] In one embodiment, a single content file 104-c may be associated with a single presentation tile 124-a. In this case, a single tile object 126-e is presented in each presentation tile 124-a. In one embodiment, multiple content files 104-c may be associated with a single presentation tile 124-a. In this case, multiple tile objects 126-e may be presented in a single presentation tile 124-a. When rendered, a content consumer may use a selector tool provided by the presentation component 130 to navigate between multiple tile objects 126-e presented in different presentation tiles 124-a, and also between multiple tile objects 126-e presented in a single presentation tile 124-a, so that the content consumer can select a tile object 126-e of interest. For instance, assume a content producer associates pictures from corresponding content files 104-1 to 104-100 with the presentation tile 124-1. Thumbnails for the 100 pictures may be generated as tile objects 126-1 to 126-100, and sized to fit within a given dimension for the presentation tile 124-1. A selector tool may be used to navigate between the tile objects 126-1 to 126-100 to select and enlarge a given picture. [0041] Once a user has completed authoring operations to associate different content files 104-c with different presentation tiles 124-a of a presentation surface 122, the authoring component 110 may store the presentation surface 122 and tile objects 126-e as part of a montage 120. [0042] The presentation component 130 may generally manage presentation operations for the montage application 140, including generating user interface views and tools to present a montage 120 on an electronic display for an electronic device. In one embodiment, for example, the presentation component 130 may generate a first user interface view to present each tile object 126-e within each associated presentation tile 124-a on the presentation surface 122 of the montage 120. The presentation component 130 may receive control directives 132-/to select a tile object 126-e, and generate a second user interface view to present a content file 104-c corresponding to the selected tile object 126-e. [0043] FIG. 2 illustrates a more detailed block diagram of the authoring component 110 of the montage application 140. The authoring component 110 may intelligently generate a tile object 126-e for an associated content file 104-c by retrieving certain portions of content from the content file 104-c based on a type definition for the content file 104-c type. For instance, the portion of content may comprise text from the content file 104-c, metadata for the content file 104-c, an object from the content file 104-c, or some combination thereof. [0044] In one embodiment, a content file 104-c may be stored in a local datastore 210 implemented within a same electronic device implementing the montage application 140. For example, a computing device may implement the montage application 140 using content files 104-1, 104-2 stored on a mass storage device of the computing device. In one embodiment, a content file 104-c may be stored in a remote datastore 212 implemented by a different electronic device as the one implementing the montage application 140. For example, a computing device may implement the montage application 140 using a content file 104-3 stored on a mass storage device of a server device. [0045] In the illustrated embodiment shown in FIG. 2, the authoring component 110 may comprise or implement multiple type modules 202-g. Each type module 202-g may correspond to a content file type for a respective content file 104-c. Examples for a content file type for a content file 104-c may include without limitation application file types, such as a word processing file type, a spreadsheet file type, a presentation file type, a PIM file type, a database file type, a publisher file type, a drawing file type, a note file type, a message file type, and so forth. Further examples for a content file 104-c may include multimedia file types, such as an audio file type, an image file type, a video file type, an AV file type, an animation file type, a game file type, a markup file type, a web page type, and so forth. It may be appreciated that these are merely a few examples of a content file types, and embodiments are not limited to these examples. [0046] A type module 202-g may retrieve information from a content file 104-c based on a type definition 204-/z for a content file type, and generate a tile object 126-e based on the retrieved information and the type definition 204-/z. A type definition 204-/z may comprise a set of definitions, rules, properties, methods, events, coordinates or instructions to extract selected portions from a content file 104-c, and format the extracted portions within a defined region of a presentation tile 124-a. By implementing specific types definitions 204-/z for specific content files 104-c, the authoring component 110 may generate highly customized tile objects 126-e specifically designed for a particular context (e.g., business, personal) and associated set of content consumers. A type definition 204-/z may be a default type definition provided with the montage application 140, or a userdefined type definition that is created using the montage application 140. [0047] By way of example, assume a content file 104-1 is a word processing document 104-1, a type module 202-1 is for a word processing file type, and a type definition 204-1 is a set of definitions for the word processing file type. The type definition 204-1 may include various types of information used in creating a tile object 126-1. For instance, the type definition 204-1 may include supported file formats associated with different versions of a word processing application, such as extensible markup language formats (e.g., .docx, .docm, .dotx, .dotm), binary formats (e.g., .doc, .dot), and open document formats (e.g., .odt). The type definition 204-1 may include security credentials (e.g., passwords, certificates, public or private keys) to access encrypted files. The type definition 204-1 may include tools to access embedded or loaded code for a file (e.g., macros, expansion packs). The type definition 204-1 may include supported fields in a document (e.g., Ask field, Author field, Database field, Fillin field, Includepicture field, Includetext field, Mailmerge field). The type definition 204-1 may include rules to handle links for a document (e.g., linked objects, master documents, template references, linked cascading style sheet references). The type definition 204-1 may include rules to handle data sets (e.g., mail merge data). The type definition 204-1 may include rules to handle object linking and embedding (OLE) objects. Other information for the type definition 204-1 is possible, and the embodiments are not limited in this context. [0048] Further, the type definition 204- 1 may contain a set of rules pertaining to types of information to retrieve from the content file 104-1. For instance, the type definition 204-1 may include three classes of information and associated rules, including a content and properties class (e.g., paragraphs or properties) from the content file 104-1, a content objects class (e.g., image, embedded object) for the content file 104-1, and a content pages class within the content file 104-1, or some combination thereof. It may be appreciated that any number of classes or categories may be defined for a given content file type. [0049] In one embodiment, examples for the content and properties class may be illustrated in TABLE 1 as follows: TABLE 1 1st Table The first table within the document • Table image is clipped to fit within the tile • For a table that contains LTR language clipping will start at a top left corner of table • For a table that contains RTL language clipping will start at top right corner of table 1st SmartArt® (filled and centered) The first SmartArt graphic within the document • SmartArt image is filled and centered within the tile 1st Chart (filled and centered) The first chart within the document • Chart image is filled and centered within the tile Table of Contents (TOC) (Web Layout) The first TOC, as it appears in web layout, within the document 1st SmartArt (shrunk) The first SmartArt graphic within the document • SmartArt image is shrunk and then centered to fit within the tile 1st Chart (shrunk) The first chart graphic within the document • Chart image is shrunk and then centered to fit within the tile 1st Equation The first equation within the document TOC (Print Layout) The first TOC, as it appears in print layout, within the document. The TOC will be clipped to fit the dimension of the tile [0051] In one embodiment, examples for the content pages class may be illustrated TABLE 3 as follows: TABLE 3 [0052] The authoring component 110 may use the type module 202-1 and associated type definition 204-1 to retrieve a content portion 106-1 from the content file 104-1 from the local datastore 210. The type module 202-1 may then organize and format the content portion 106-1 to generate the tile object 126-1. For instance, a rule for the type definition 204- 1 may state that any text retrieved from within the document, such as the first N paragraphs, will retain style formatting as specified within a document. Another rule may be that content properties that are not actual text within a document will be formatted as Normal style as defined within the document. Yet another rule may be that if the entire text of the content portion 106-1 cannot fit within the dimensions of the presentation tile 124-1 then an ellipsis " . . ." will be appended at the end of the text. These are merely some exemplary rules, and others are possible. The embodiments are not limited in this context. [0053] In some cases, the type definition 204-1 may define a set of rules to create the tile object 126-1 from a combination of a content and properties class, a content object class, and a content page class, sometimes referred to informally as a "mashup." This provides for a highly customized tile object 126-1 constructed to represent content of the content file 104-1. [0054] In one embodiment, examples for different class combinations may be illustrated in TABLE 4 as follows: TABLE 4 [0055] The type definition 204-1 may also provide rules limiting the tile object 126-1 to a single class or type within a class. For instance, a rule may define the type module 202- 1 to only use content in the form of text from the content file 104-1, or content objects in the form of images for the content file 104-1. [0056] The type definition 204-1 may further identify a device to generate the tile object 126-1 for the content file 104-1. For instance, a rule may define the type module 202-1 to interact with a server device to generate and retrieve the tile object 126-1. [0057] The type definition 204- 1 may still further provide rules to generate a list of multiple versions of the tile object 126-1 for presentation to a user for final selection. For instance, a rule may generate P versions of the tile object 126-1, with P representing any positive integer (e.g., P = 10). A list of multiple versions of the tile object 126-1 may be generated in accordance with examples given in TABLE 5 as follows: TABLE 5 TOC (Web Layout) Page 1st Table Content Object 1st Image (not in table) Content Object 1st Chart (shrunk) Content Object 1st SmartArt (shrunk) Content Object 1st Equation Content Object Title (1st instance of title style) Content/Property 1st Page (Print Layout + shrunk) Page Cover Page (Web Layout) Page TOC (Print Layout) Content Object Author Content/Property First N Headings Content/Property [0058] The type module 202-g may generate a tile object 126-e using additional information to that provided by a type definition 204-/z. For instance, a type module 202-g may receive as input information about a presentation tile 124-a selected for a content file 104-a. A type module 202-g may receive information such as a location, size, shape, dimension, geometry, boundaries, adjacent presentation tiles 124-a, adjoining presentation tiles 124-a, and so forth. For instance, if a type module 202-1 is using type definition 204- 1 to construct a tile object 126-1 that is too large for current dimensions of a presentation tile 124-1, the type module 202-1 may use information about adjacent or adjoining presentation tiles 124-2, 124-3 to determine whether the current dimensions for the presentation tile 124-1 may be increased to accommodate a larger tile object 126-1, and the current dimensions for the presentation tiles 124-2, 124-3 may be decreased accordingly. The authoring component 110 may implement various fitting algorithms to accommodate such cases. [0059] FIG. 3A illustrates an embodiment of a user interface view 300 generated by the authoring component 110. The user interface view 300 may include a presentation surface 122 with a number of empty presentation tiles 124-a before any tile objects 126-e have been created for the content files 104-c. The user interface view 300 may also include various graphical user interface (GUI) tools 302-s for receiving control directives 102-6 from an author, such as a copy command 302-1, a cut command 302-2, and a paste command 302-3. Other GUI tools 302-s may be used beyond those shown in FIG. 3A, such as a move command, a paste special command, and so forth. [0060] The user interface view 300 may further include a file navigation tool 304. The file navigation tool 304 may comprise a file manager application for a given OS designed for navigating a file system with stored data files. For instance, the file navigation tool 304 may be used to navigate and present various content files 104-c from the local datastore 210 or the remote datastore 212. An example of a file navigation tool 304 may include MICROSOFT WINDOWS EXPLORER designed for a MICROSOFT WINDOWS operating system. Other file navigation tools may be used as well. [0061] During authoring operations, the authoring component 110 may receive a control directive 102-6 to associate the content file 104-1 with the presentation tile 124-1 from an input device, such as a pointing device 308 or a gesture 310 on a touch-screen display, for example. For instance, a content producer may create a montage 120 by utilizing the file navigation tool 304 to navigate and present content files 104-c stored by one or both datastores 210, 212. The content producer may use various input devices, such as a pointing device 308 or a gesture 310 on a touch-screen display, to select a content file 104- c for a presentation tile 124-a. As shown, the pointing device 308 may be used to select the content file 104-1 and use a drag-and-drop technique to move the content file 104-1 over the presentation tile 124-1. Alternatively, the GUI input tools 302 may be used to perform similar operations. [0062] FIG. 3B illustrates an embodiment of a user interface view 320 generated by the authoring component 110. The user interface view 320 may include a presentation surface 122 with a filled presentation tile 124-1 after a tile object 126-1 has been created for the content file 104-1. Once the content producer selects the content file 104-1 and associates it with the presentation tile 124-1, the authoring component 110 may identify a content file type for the content file 104-1. In this example, the authoring component 110 identifies the content file type for the content file 104-1 as an application file type, and more particularly, a word processing file. The authoring component 110 may utilize the type module 202-1 and the type definition 204-1 specifically designed for generating tile objects from word processing files. The type module 202-1 may use the type definition 204-1 to retrieve the appropriate content portion 106-1 from the content file 104-1, with the content portion 106-1 comprising information of a content and properties class, a content objects class, a content pages class, or a class combination. The type module 202- 1 may use the content portion 106-1 to generate the tile object 126-1, and present the tile object 126-1 within boundaries of the presentation tile 124-1. [0063] FIG. 4 illustrates an example of the authoring component 110 generating the tile object 126-1. As shown, the content file 104-1 may comprise various types of information of the content and properties class, including a title 402, a first paragraph 404, a second paragraph 406, and various metadata 408. The content file 104-1 may further comprise various types of information of the content objects class, including an image 410, a bar chart 412, and an equation 414. The type definition 204-1 may include five rules, including a first rule to use a specific tile template labeled "Tile Template 1," a second rule to retrieve a title 402, a third rule to retrieve an author from metadata 408, a fourth rule to retrieve a first N paragraphs 404, 406 (e.g., = 2), and a fifth rule to retrieve a first graph, which in this case is the bar chart 412. The type module 201-1 may use the type definition 204-1 to retrieve the content portion 106-1 from the content file 104-1 according to rules 1-5 of the type definition 204-1, and generate the tile object 126-1, which is presented as a user interface view with the specific information of the content portion 106- 1 formatted according to "Tile Template 1." [0064] FIG. 5 illustrates an embodiment of a messaging system 500 suitable for publishing or distributing a montage 120 generated by the montage application 140. A content producer may generate a montage 120 using the montage application 140 using various user interface views provided by the user interface component 540. The user interface 538 may comprise a native user interface component for the montage application 140, or a user interface component for an OS executing the montage application 140 (e.g., Microsoft Windows). Once a montage 120 has been generated, a content producer may distribute the montage 120 to various content consumers using a publishing model, a messaging model, or a combination of a publishing model and a messaging model. [0065] In one embodiment, the montage application 140 may use a publishing component 532 to publish a montage and associated content files 104-c from a local datastore 210 to the remote datastore 212. The remote datastore 212 may be implemented as part of a network storage server 550 accessible by a network service, such as a social networking service (SNS), for example. Content consumers may access the network service to view the network service versions. [0066] In one embodiment, the montage application 140 may use a native message component 534 to send a montage 120 and associated content files 104-c as a message 516 and message attachments via a messaging architecture, such as a message server 540. Content consumers may access and view the message versions. Alternatively, the montage application 140 may use an external (non-wative) message application 542-k. [0067] In one embodiment, the montage application 140 may use a combination of both the publishing model and the messaging model, by publishing a montage 120 and associated content files 104-c to a network service, receive links 518-w for network versions of the montage 120 and associated content files 104-c, and send a message 516 with the links 5 18- . Content consumers may access the message 516, select a link 5 18-w, and view the network version of the montage 120. Further, content consumers may select a tile object 126-e of the montage 120 to view the network version of the content file 104- c associated with the selected tile object 126-e. [0068] The montage application 140 may use a security component 536 to manage permissions and access to a montage 120 and associated content files 104-c by content consumers. The security component 536 may manage accounts, authentication information, authorization information, security information (e.g., encryption/decryption algorithms, security keys, certificates, etc.), permission levels, and so forth. In one embodiment, the security component 536 may receive a control directive from an input device representing a command from a content producer to authorize communicating content files 104-c from the local datastore 210 to the remote datastore 212 for the network storage server 550 accessible by a network service. [0069] In the illustrated embodiment shown in FIG. 5, the messaging system 500 may comprise multiple computing devices 510-7, a message server 540 and a network storage server 550 all communicating over a network 530. The computing devices 510-7 may each implement the montage application 140 and/or one or more message applications 542-k. Although the messaging system 500 as shown in FIG. 5 has a limited number of elements in a certain topology, it may be appreciated that the messaging system 500 may include more or less elements in alternate topologies as desired for a given implementation. [0070] The network 530 may comprise a communications framework designed to communicate information between the various devices of the messaging system 500. The network 530 may implement any well-known communications techniques, such as techniques suitable for use with packet-switched networks (e.g., public networks such as the Internet, private networks such as an enterprise intranet, and so forth), circuit-switched networks (e.g., the public switched telephone network), or a combination of packetswitched networks and circuit-switched networks (with suitable gateways and translators). [0071] The message server 540 may comprise or employ one or more server computing devices and/or server programs that operate to perform various methodologies in accordance with the described embodiments. For example, when installed and/or deployed, a server program may support one or more server roles of the server computing device for providing certain services and features. Exemplary message server 540 may include, for example, stand-alone and enterprise-class server computers operating a server OS such as a MICROSOFT OS, a UNIX® OS, a LINUX® OS, or other suitable serverbased OS. Exemplary server programs may include, for example, communications server programs such as MICROSOFT OFFICE COMMUNICATIONS SERVER (OCS) for managing incoming and outgoing messages, messaging server programs such as MICROSOFT EXCHANGE SERVER for providing unified messaging (UM) for e-mail, voicemail, VoIP, instant messaging (IM), group IM, enhanced presence, and audio-video conferencing, and/or other types of programs, applications, or services in accordance with the described embodiments. [0072] The network storage server 550 may also comprise or employ one or more server computing devices and/or server programs that operate to perform various methodologies in accordance with the described embodiments. For example, when installed and/or deployed, a server program may support one or more server roles of the server computing device for providing certain services and features. Exemplary network storage server 550 may include, for example, stand-alone and enterprise-class server computers operating a server OS such as a MICROSOFT OS, a UNIX OS, a LINUX OS, or other suitable serverbased OS. Exemplary server programs may include, for example, network storage server programs such as MICROSOFT LIVE providing online network storage of documents and files, including multimedia or media files such as images, photographs, photo albums, videos, video albums, and so forth. Exemplary server programs may further include, for example, network application programs such as social networking application programs, search applications, document management programs, weblogs (blogs), word processing programs, spreadsheet programs, database programs, drawing programs, document sharing programs, message applications, web services, web applications, web server, and/or other types of programs, applications, or services in accordance with the described embodiments. [0073] The computing devices 5 10 - may each comprise a processor 502 and a memory 504 communicatively coupled to the processor 502. The processor 502 and the memory 504 may each be communicatively coupled to a communication interface 509. An exemplary architecture and examples for computing devices 510-7 may be described with reference to FIG. 10. [0074] The communication interface 509 may comprise or implement various communication techniques to allow the computing devices 510-7 to communicate with each other and the other devices of the messaging system 500 via the network 530. For instance, the various devices of the messaging system 500 may each include a communication interface 509 that implements various types of standard communication elements designed to be interoperable with the network 530, such as one or more communications interfaces, network interfaces, network interface cards (NIC), radios, wireless transmitters/receivers (transceivers), wired and/or wireless communication media, physical connectors, and so forth. By way of example, and not limitation, communication media includes wired communications media and wireless communications media. Examples of wired communications media may include a wire, cable, metal leads, printed circuit boards (PCB), backplanes, switch fabrics, semiconductor material, twisted-pair wire, co-axial cable, fiber optics, a propagated signal, and so forth. Examples of wireless communications media may include acoustic, radio-frequency (RF) spectrum, infrared and other wireless media. [0075] In various embodiments, the communication interface 509 may comprise multiple different types of transports 512-m. Each of the transports 512-m may implement or utilize a same or different set of communication parameters to communicate information between the various devices of the messaging system 500. In one embodiment, for example, each of the transports 5 12-m may implement or utilize a different set of communication parameters to communicate information between the computing devices 510-7 and the message server 540. Some examples of communication parameters may include without limitation a communication protocol, a communication standard, a radio-frequency (RF) band, a radio, a transmitter/receiver (transceiver), a radio processor, a baseband processor, a network scanning threshold parameter, a radiofrequency channel parameter, an access point parameter, a rate selection parameter, a frame size parameter, an aggregation size parameter, a packet retry limit parameter, a protocol parameter, a radio parameter, modulation and coding scheme (MCS), acknowledgement parameter, media access control (MAC) layer parameter, physical (PHY) layer parameter, and any other communication parameters affecting operations for the communication interface 509 implemented by the computing devices 5IO-7. The embodiments are not limited in this context. [0076] In various embodiments, the communication interface 509 of the computing device 510-1 may implement different communication parameters offering varying bandwidths or communications speeds. For instance, the transport 512-1 may comprise a high-speed interface implementing suitable communication parameters for high-speed communications of information to the network 530, while the transport 5 12-2 may comprise a low-speed interface implementing suitable communication parameters for lower-speed communications of information to the network 530. [0077] With respect to wired communications, for example, the transport 5 12-1 may comprise a network interface designed to communicate information over a packetswitched network such as the Internet. The transport 512-1 may be arranged to provide data communications functionally in accordance with different types of wired network systems or protocols. Examples of suitable wired network systems offering data communication services may include the Internet Engineering Task Force (IETF) Transmission Control Protocol (TCP) and the Internet Protocol (IP) suite of communications standards, the User Datagram Protocol (UDP), the Datagram Congestion Control Protocol (DCCP), the Stream Control Transmission Protocol (SCTP), the Resource Reservation Protocol (RSVP), the Explicit Congestion Notification (ECN) protocol, the Open Shortest Path First (OSPF) suite of protocols, Reliable Transport Protocol (RTP), the IETF Real-Time Transport Protocol (RTP), and so forth. The transport 5 12-2 may be arranged to provide data communications in accordance with different message protocols, such as the Simple Mail Transfer Protocol (SMTP), extended SMTP (ESMTP), Post Office Protocol (POP), POP3, the Internet Message Access Protocol (IMAP), Multipurpose Internet Mail Extensions (MIME) protocol, Unix-to-Unix Copy (UUCP) protocol, the International Telecommunication Union (ITU) suite of protocols such as the ITU-T X.400 protocol, and so forth. It may be appreciated that other wired communications techniques may be implemented, and the embodiments are not limited in this context. [0078] With respect to wireless communications, for example, the transport 5 12-1 may comprise a radio designed to communicate information over a wireless local area network (WLAN). The transport 512-1 may be arranged to provide data communications functionality in accordance with different types of wireless network systems or protocols. Examples of suitable wireless network systems offering data communication services may include the Institute of Electrical and Electronics Engineers (IEEE) 802.xx series of protocols, such as the IEEE 802.1 la/b/g/n series of standard protocols and variants (also referred to as "WiFi"), the IEEE 802.16 series of standard protocols and variants (also referred to as "WiMAX"), the IEEE 802.20 series of standard protocols and variants, and so forth. The transport 512-2 may comprise a radio designed to communication information across data networking links provided by one or more cellular radiotelephone systems. Examples of cellular radiotelephone systems offering data communications services may include GSM with General Packet Radio Service (GPRS) systems (GSM/GPRS), CDMA/lxRTT systems, Enhanced Data Rates for Global Evolution (EDGE) systems, Evolution Data Only or Evolution Data Optimized (EV-DO) systems, Evolution For Data and Voice (EV-DV) systems, High Speed Downlink Packet Access (HSDPA) systems, High Speed Uplink Packet Access (HSUPA), and so forth. It may be appreciated that other wireless techniques may be implemented, and the embodiments are not limited in this context. [0079] In various embodiments, the communication interface 509 of the computing device 510-1 may implement a same set of communication parameters offering identical or substantially similar bandwidths or communications speeds. However, the transports 512-1, 512-2 may be utilized by the montage application 140 and/or the message application 542- 1 at different points in time. In one embodiment, for instance, the montage application 140 may communicate a montage 120 and one or more content files 104-c for the montage 120 during a first time interval, and the montage application 140 and/or the message application 542-1 may communicate a message 516 with information pertaining to the montage 120 and/or supporting content files 104-c during a second time interval. In one embodiment, for example, the first and second time intervals may be completely discontinuous, where a start time and an end time for the first time interval are before a start time for the second time interval. In one embodiment, for example, the first and second time intervals may be partially overlapping, where a start time for the first time interval is before a start time for the second time interval but the end time for the first time interval is after the start time for the second time interval. The embodiments are not limited in this context. [0080] The computing devices 5 10 - may each implement the montage application 140 with the message component 534 and/or one or more message applications 542-k arranged to communicate various types of messages in a variety of formats. One embodiment will be described with reference to the message applications 542-k for the messaging model, although such descriptions may apply to other embodiments utilizing the message component 534 of the montage application 140. [0081] Each of the message applications 542-k may be representative of a particular kind of transport, enabling handling of messages of particular types and formats for the particular application. The message applications 542-k may comprise without limitation a facsimile application, a video message application, an instant messaging (IM) application, a chat application, an electronic mail (email) application, a short message service (SMS) application, a multimedia message service (MMS) application, a social network system (SNS) application, and so forth. It is to be understood that the embodiments are not limited in this regard and that the message applications 542-k may include any other type of messaging or communications application which is consistent with the described embodiments. It also is to be appreciated that the computing devices 510-7 may each implement other types of applications in addition to message applications 542-k which are consistent with the described embodiments. [0082] As shown in FIG. 5, for example, the computing devices 510-1, 510-2 implement respective message applications 542-1, 542-2. The message applications 542-1, 542-2 may generally operate to generate, send, receive, update, modify and otherwise manage messages for the computing devices 510-1, 510-2. It may be appreciated that the implementation details shown for the computing device 510-1 and its message application 542-1 as described herein also applies to the computing device 510-2 and its respective message application 542-2. [0083] In one embodiment, the message applications 542-1, 542-2 are implemented as stand-alone client-based applications stored and executed by local resources provided by the computing devices 510-1, 510-2, such as the processor 502 and the memory 504 of the computing device 510-1, rather than network based message applications implemented on network devices and accessed by the computing devices 510-1, 510-2 via a web browser. In one embodiment, the message applications 542-1, 542-2 may comprise distributed applications suitable for distributed processing and partially executing on local resources for the computing devices 510-1, 510-2 and partially executing on network resources. Additionally or alternatively, the message applications 542-1, 542-2 may comprise network based message applications implemented on network devices and accessed by the computing devices 510-1, 510-2 via a web browser. The embodiments are not limited in this context. [0084] In one embodiment, for example, the message application 542-1 may be arranged to communicate a message 516 over a transport 512-2. The message 516 may include one or more embedded links 518-w for a montage 120 and/or one or more content files 104-c and/or a montage 120 when communicated over the transport 512-2. The one or more embedded links 518-w may comprise, for example, a reference to the montage 120 and/or the one or more content files 104-c as stored on the network storage server 550 and accessible by a message sender or a message recipient. [0085] Each of the links 518- may comprise a reference or pointer to stored montage 120 and content files 104-c that a user can directly follow, or that is followed automatically by a program. References are data types that refer to a referent (e.g., stored montage 120 and content files 104-c such as an object, file, data item, and so forth) elsewhere in memory of a device (e.g., a file server) and are used to access the referent. Generally, a reference is a value that enables a program to directly access the referent. The referent may be stored on a same device as the reference or a different device as the reference. Most programming languages support some form of reference. Examples for the links 5 18-w may include without limitation hypertext and hyperlinks, such as those used by the World Wide Web (WWW). Hypertext is text with hyperlinks. A hyperlink typically comprises an anchor, which is a location within a message from which the hyperlink can be followed. The target of a hyperlink is the stored montage 120 and/or content file 104-c to which the hyperlink leads. The user can follow the link when its anchor is shown by activating it in some way, such as by touching it (e.g., with a touch screen display) or clicking on it with a pointing device (e.g., a mouse). When a link 518-« is activated its target is displayed, via a web browser or an application program. [0086] As previously described, the montage application 140 may use a hybrid of both the publishing model and the messaging model, by publishing a montage 120 and associated content files 104-c to the remote datastore 212 of the network storage server 550, receive links 518- for network versions of the montage 120 and associated content files 104-c, and send a message 516 with the links 518- . Content consumers may access a message 516, select a link 518-w, and view the network version of the montage 120. Further, content consumers may select a tile object 126-e of the montage 120 to view the network version of the content file 104-c associated with the selected tile object 126-e. This hybrid model may be described in more detail with reference to FIG. 6. [0087] FIG. 6 illustrates an embodiment of a message flow for the messaging system 500. As shown in FIG. 6, the publishing component 532 may publish a montage 120 and associated content files 104-c to a network service 652. The publishing component 532 may send the montage 120 and associated content files 104-c to the network storage server 550 over the transport 512-1 as indicated by arrow 602. As a high-speed transport, the transport 5 12-1 may have sufficient bandwidth to transport larger file size typically associated with the content files 104-c, relative to a message size for a message 516, for example. [0088] The network storage server 550 may receive the montage 120 and the associate content files 104-c, and store them in the remote datastore 212. The network storage server 550 may then send links 518-w to the montage 120 and the content files 104-c as stored in the remote datastore 212, as indicated by arrow 604. [0089] The publishing component 532 may receive the links 518- , and forward the links to the authoring component 110. The authoring component 110 may associate a link 518-w with each tile object 126-e, and update the montage 120 with the associations so that a content consumer can select a tile object 126-e and access an associated content file 104-c from the remote datastore 212 for deeper viewing of the content file 104-c. [0090] In one embodiment, consistent with the publishing model, the authoring component 110 may send the updated montage 120 to the publishing component 532. The publishing component 532 may then publish the updated montage 120 and the links 5 18- on the network service 652 as indicated by arrow 606. For instance, the network service 652 may comprise a social networking service (SNS), and content consumers having a defined relationship with the content producer (e.g., friends) may access the montage 120 and associated content files 104-c via the published links 5 18-w. In another example, the network service 652 may provide an account to the content producer, which can be enabled for viewing by content consumers according to permissions set for the network service 652 and/or the security component 536. A content consumer may access the network service 652 via the computing device 510-2, select the link 518- to a file for the montage 120 via a web browser, request the montage 120 from the remote datastore 212 as indicated by arrow 610. The network service 652 may receive the request, and send the montage 120 to the computing device 5 10-2 as indicated by arrow 612. The computing device 510-2 may present the montage 120 as a user interface view of the presentation surface 122 with the tile objects 126-e in the presentation tiles 124-a. The computing device 510-2 may generate a user interface view as a web page for a web browser, or as a user interface view of an application program, such as the montage application 140 or a montage viewer designed to view a montage 120. [0091] In one embodiment, consistent with the messaging model, the authoring component 110 may forward the updated montage 120 and links 518- to the message component 534 (or message application 542-1). The message component 534 may receive as inputs the links 518-w and message content 620. The message content 620 may comprise a message from the content producer. The message component 534 may generate a message 516 with the message content 620 and the links 5 18-w. Additionally or alternatively, the message 516 may optionally include the montage 120 and/or certain content files 104-c depending on file size restrictions and available bandwidth on the message transport 5 12-2. The montage 120 may comprise a full-fidelity version of the montage 120, or a lower- fidelity version of the montage 120 more suitable for available bandwidth of the transport 512-2, such as a thumbnail version of the montage 120. [0092] The message component 534 may send the message 516 over the transport 512-2 to the message application 542-2 of the computing device 510-2 via the message server 540 as indicated by arrow 608. A content consumer may open the message 516, select the link 5 18- to the montage 120, and request the montage 120 from the remote datastore 212 as indicated by arrow 610. The network service 652 may receive the request, and send the montage 120 to the computing device 5 10-2 as indicated by arrow 612. The computing device 510-2 may present the montage 120 as a user interface view of the presentation surface 122 with the tile objects 126-e in the presentation tiles 124-a. The computing device 510-2 may generate a user interface view as a web page for a web browser, or as a user interface view of an application program, such as the montage application 140 or a montage viewer designed to view a montage 120. [0093] FIG. 7A illustrates an embodiment of a user interface view 700 of an exemplary message 516. As described with reference to FIG. 6, a content producer may use the montage application 140 and/or the messaging application 542-1 to generate and send a message 516 with a montage 120 or a reference to the montage 120. A content consumer may receive the message 516 via the computing device 510-2 and the messaging application 542-2. The user interface view 700 provides an example for a message 516 implemented as an email message. [0094] The message 516 may comprise a ribbon bar 702 having various command elements for an email, such as a Reply button, a Reply to All button, a Forward button, a Delete button, a Move to Folder button, and a Create Rule button, among others. The message 516 may further comprise an address bar 704 with addressing information, and a message body 706. The message body 706 may comprise a surface having montage file thumbnail 720 and a link 518-1 to the montage 120 as stored in the remote datastore 212. The montage file thumbnail 720 may comprise a lower- fidelity version of the montage 120. [0095] A content consumer may select the montage thumbnail 720 using an input device, such as a pointing device 710, for example. A content consumer may also select the link 518-1 titled "Student Class Trip" using an input device, such as a gesture 712 on a touch-screen display, for example. In both cases, the selection launches a web browser or an application program to view the montage 120. [0096] FIG. 7B illustrates an embodiment of a user interface view 740 of a montage 120 once launched from the message 516. Depending on a given implementation for the computing device 510-2, the computing device 510-2 may generate the user interface view 740 as a web page for a web browser, or as a user interface view of an application program, such as the montage application 140 or a montage viewer 730 specifically designed to view a montage 120. For instance, the presentation component 130 of the montage application 140 implemented for the computing device 510-2 and/or the montage viewer 730 may receive a control directive to open the montage 120, and initiate operations to retrieve the montage 120 from the remote datastore 212. The presentation component 130 and/or the montage viewer 730 may present the user interface view 740 of the montage 120, including the presentation surface 122 with the tile objects 126-e in the appropriate presentation tiles 124-a. [0097] When rendered as a web page, the presentation component 130 may use code specifically designed for a web page, such as Hypertext Markup Language (HTML) or similar code. However, HTML code may be limited by a given type of web browser implemented by the client device 510-2. When rendered as a user interface view for the montage viewer 730, the presentation component 130 and/or the montage viewer 730 may use code optimized for the montage viewer 730. For instance, a montage 120 may be generated using HTML code for a web page, with extensible markup language (XML) code embedded within the HTML code. The XML code may be generated with a data schema specifically designed for the montage application 140 or the montage viewer 730. As such, the montage application 140 or the montage viewer 730 may render a higherfidelity version of the montage 120 relative to a lower- fidelity version of the montage 120 used for a web page. [0098] FIG. 7C illustrates an embodiment of a user interface view 750 of an example of a montage 120 as presented in the montage viewer 730. As described with reference to FIG. 7B, the montage viewer 730 may present the user interface view 740 of the montage 120, including the presentation surface 122 with the tile objects 126-e in the appropriate presentation tiles 124-a. Assume that the presentation surface 122 includes the tile object 126-1 for the content file 104-1 as described with reference to FIG. 4. [0099] A content consumer may select the tile object 126-1 using an input device, such as a pointing device 710, for example. The presentation component 130 of the montage application 140 implemented for the computing device 510-2 and/or the montage viewer 730 receives a control directive to select the tile object 126-1, and retrieves the content file 104-1 for the tile object 126-1 from the remote datastore 212. [00100] FIG. 7D illustrates an embodiment of a user interface view 760 of a content file 104-1 once launched from the montage 120. The presentation component 130 and/or the montage viewer 730 may present the user interface view 760 with a full-fidelity version of the content file 104-1 retrieved from the remote datastore 212. Alternatively, a content file 104-1 may be rendered using a native application program similar to the one used to generate the content file 104-1, or a viewer specifically designed for such an application program. The embodiments are not limited in this context. [00101] In various embodiments, the presentation component 130 may dynamically generate a montage 120 for viewing on displays having different properties, such as different sizes, resolution, refresh rates, backlighting, power consumption, and so forth. In such cases, the presentation component 130 may be arranged to detect display properties of a display, and modify a montage 120 for presentation on the display. For instance, the presentation component 130 may generate a much larger version of a montage 120 with a greater number of presentation tiles 124-a and tile objects 126-e when presented on a large wall display with touch controls as found in many conference rooms. Meanwhile, the presentation component 130 may generate a smaller version of a montage 120 with a fewer number of presentation tiles 124-a and tile objects 126-e when presented on a smart phone. Similarly, the presentation component 130 may generate a montage 120 with different levels of fidelity based on screen resolution or pixel size of a given display. In another example, the presentation component 130 may generate one version of a montage 120 when in portrait mode, and another version of the montage 120 when in panoramic mode, such as when a user rotates a smart phone or tablet. The embodiments are not limited in this context. [00102] Operations for the above-described embodiments may be further described with reference to one or more logic flows. It may be appreciated that the representative logic flows do not necessarily have to be executed in the order presented, or in any particular order, unless otherwise indicated. Moreover, various activities described with respect to the logic flows can be executed in serial or parallel fashion. The logic flows may be implemented using one or more hardware elements and/or software elements of the described embodiments or alternative elements as desired for a given set of design and performance constraints. For example, the logic flows may be implemented as logic (e.g., computer program instructions) for execution by a logic device (e.g., a general-purpose or specific -purpose computer). [00103] FIG. 8 illustrates one embodiment of a logic flow 800. The logic flow 800 may be representative of some or all of the operations executed by one or more embodiments described herein, such as the authoring component 110 of the montage application 140. [00104] In the illustrated embodiment shown in FIG. 8, the logic flow 800 may provide a presentation surface having multiple presentation tiles at block 802. For example, the authoring component 110 may provide a presentation surface 122 having multiple presentation tiles 124-a via the user interface 538. The presentation surface 122 may be selected from among a number of montage templates, or custom designed by a content producer. [00105] The logic flow 800 may receive a control directive to associate a content file with a presentation tile at block 804. For example, the authoring component 110 may receive a control directive 102-6 to associate a content file 104-c with a presentation tile 124-a. The control directive 102-6 may be from an input device representing a command by the content producer. [00106] The logic flow 800 may identify a content file type for the content file at block 806. For example, the authoring component 110 may identify a content file type for the content file 104-c. Identification may be performed by inspecting a file extension of the content file 104-c, metadata for the content file 104-c, analysis of information within the content file 104-c, information for an application program used to produce the content file 104-c, and so forth. [00107] The logic flow 800 may retrieve a portion of content from the content file based on the content file type at block 808. For example, the authoring component 110 may select a type module 202-g based on the content file type, and use the selected type module 202-g to retrieve appropriate content portion 6-d from the content file 104-c in accordance with a type definition 204-/z associated with the content file type discovered for the content file 104-c. In one embodiment, the content file 104-c may be stored in the local datastore 210, and the content portion 106-d retrieved over a data bus using the file navigation tool 304. In one embodiment, the content file 104-c may be stored in the remote datastore 212, and the content portion 106-
