Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates to document presentation. More specifically, the present invention relates to processing a document to display the document differently depending on a context of the document. 
     2. Description of Related Art 
     Existing systems for display of a document used controls which specify, for example, a normal view, an outline view, a zoomed view, a paged view, etc. However, the foregoing concept is limited in scope. 
     These systems avoid duplication of content by customizing the same content for reuse based on the display context. Some examples of the technologies used to provide this context sensitive display of content include Extensible Markup Language (XML), Cascading Style Sheets (CSS) and JavaScript. 
     Much of the content displayed on the world wide web is duplicated in different documents in order to render the content in multiple display contexts needed by users. The types of display contexts include popup windows, full windows, etc., display on limited function personal digital assistants, full function displays, displaying the same content with different navigation options, mastheads and footers. The content can be accessed directly via an address such as a URL or indirectly by the user clicking on a link. 
     These systems for customizing the reuse of content based on the display context are limited by their dependence on stored user preferences. 
     Therefore, a need exists for an improved method for displaying a document differently depending on a context. 
     SUMMARY OF THE INVENTION 
     According to an embodiment of the present disclosure, a computer readable medium is provided embodying instructions executable by a processor to perform a method for modifying a document according to a display context, the method comprising providing a document for display, the document comprising a function for determining a display context and modifying a style of the document, determining the display context for display of the document, modifying the style of the document according to the context, and displaying the document according to a modified style. 
     The method includes assigning a window name to the document. 
     The display context is determined according to a location sensitive attribute. 
     According to an embodiment of the present disclosure, a computer readable medium is provided embodying instructions executable by a processor to perform a method for creating a link in a document for displaying the document in a different context. The method comprises storing a collection of documents stored in a database, selecting a document from the collection, presenting a plurality of different potential visual representations for a selected document for selection by a user, determining a selected visual representation, creating a link to the selected document which specifies a style of the selected document according to a chosen visual representation, and displaying at least one of the selected documents. 
     The method includes determining a context for display of the selected document, modifying the style of the selected document upon determining that a context is different than the chosen, visual representation. 
     The link is associated with selected text of the document in a different visual representation than the chosen visual representation. 
     The method includes displaying the link in a graphical user interface for creating the link.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     Embodiments of the present invention disclosure herein are intended to foe illustrative only, since numerous modifications and variations therein will be apparent to those of ordinary skill in the art. In reference to the drawings, like numbers will indicate like parts continuously throughout the views. 
     According to an embodiment of the present disclosure, a document, such as a web page, is augmented by an application, e.g., JavaScript and CSS files, to be displayed differently depending on context, for example, being presented in full screen vs. popup windows. According to an embodiment of the present disclosure, content reuse uses location sensitive attributes and values within a document&#39;s environment to dynamically determine the display context. For example, a parameter of a window.open( ) method may be determined by the function to determine a context. Document reuse in different contexts is implemented using transformations of styles of the document. 
     An application creates more than one identical or similar document; during a linking process, an author has a choice to link to a document capable of being displayed differently in different windows. 
     In an exemplary implementation, in the case of popup contexts, the design of documents and associated programming tools enable the same document to be displayed as a popup without the associated navigation, elements. 
     Referring to  FIG. 1A , an input document is authored or provided  101 , and using a combination of CSS and JavaScript along with HTML authoring of documents, content is produced for the document, e.g., a single page, to be used in multiple contexts. A main style (e.g., a CSS) is used to render the main view of an HTML document with all the elements visible  102 , including mastheads, navigation, footers, etc. In addition, the HTML document has a JavaScript function, or set of functions, embedded in it  103  that generates the popup window if called, explicitly assigning a window name and altering the main styles  104  to produce a web page with the same content but a different visual experience based on the current window name  105 . 
     The follow exemplary HTML code shows empty script and style elements:

                 .

                 &lt;/body&gt; 
               
               
                   
                 &lt;/html&gt; 
               
               
                   
                   
               
             
          
         
       
     
     The embedded function, e.g., in a script element of the HTML document, is evaluated as the document loads, wherein the function determines current attributes and values of the environment and determines whether to modify a style of the document to affect a display of contents of the document according to the attributes and values of the environment, e.g., the context. 
       FIG. 2A  shows a normal web page view  201  and a popup web page view  202  of the same document. In  FIG. 2A  it can be seen that the function of the document has modified the style of document displayed in the popup window to hide the indication of date  203  and navigation tools  204 , which are displayed in the normal window  201 . 
     The HTML document author would therefore be able to create context sensitive pages by inserting appropriate functions in HTML documents that have already been created. 
     In another exemplary implementation, using the exemplary methodology of  FIG. 1A , for the design of documents, a document database and associated programming tools are provided which enable an HTML document author to choose and automatically create links between HTML documents and to select a context, e.g., main view or popup view, in which the documents are to be displayed. 
     Referring to  FIG. 1B , using a document database for HTML authoring, CSS and JavaScript, an HTML document author can produce a collection of HTML web pages. According to an embodiment of the present disclosure, by having a collection of documents stored in a central database  106 , e.g., wherein an application for authoring the HTML web pages is aware of the web pages for a site, e.g., page names such as index.html. Different representations of the documents may be selected for display in different display environments. The author is presented with a graphical user interface (GUI) for selecting documents from the collection  107  and automatically creating links between those documents  108 . Given these links, the author can choose which visual representation, for example, a normal web page view or a popup web page view, in which to display each HTML document  109 . A function is embedded in each selected document, or modified if already present, to alter a corresponding style of each selected document according to chosen visual representations (see  FIG. 1A ). 
     Referring to  FIG. 2B , the selection of documents and contexts for authoring a web site including documents may be performed through the GUI, which for example, allows an author to select a type of link  205  associated with selected text  206  (e.g., selected from an HTML editor), select a type of page to be linked to, including linked content  207 , the page to be linked to  208  and a default context  209 . The GUI may also display the created link  210  inserted into the authored HTML document. Should the context be different than the default context, the embedded function will adapt the document to the actual context (see for example,  FIG. 1A ), for example, if a user explicitly changes a context by specifying a tabbed view context rather than a popup window view of the document. 
     It is to foe understood that the present invention may be implemented in various forms of hardware, software, firmware, special purpose processors, or a combination thereof. In one embodiment, the present invention may be implemented in software as an application program tangibly embodied on a program storage device. The application program may be uploaded to, and executed by, a machine comprising any suitable architecture. 
     Referring to  FIG. 3 , according to an embodiment of the present invention, a computer system  301  for implementing a method for displaying a document differently depending on a context can comprise, inter alia, a central processing unit (CPU)  302 , a memory  303  and an input/output (I/O) interface  304 . The computer system  301  is generally coupled through the I/O interface  304  to a display  305  and various input devices  306  such as a mouse and keyboard. The support circuits can include circuits such as cache, power supplies, clock circuits, and a communications bus. The memory  303  can include random access memory (RAM), read only memory (ROM), disk drive, tape drive, etc., or a combination thereof. The present invention can be implemented as a routine  307  that is stored in memory  303  and executed by the CPU  302  to process the signal from the signal source  308 . As such, the computer system  301  is a general-purpose computer system that becomes a specific purpose computer system when executing the routine  307  of the present invention. 
     The computer platform  301  also includes an operating system and micro instruction code. The various processes and functions described herein may either be part of the micro instruction code or part of the application program (or a combination thereof) which is executed via the operating system. In addition, various other peripheral devices may be connected to the computer platform such as an additional data storage device and a printing device. 
     It is to be further understood that, because some of the constituent system, components and method steps depicted in the accompanying figures may be implemented in software, the actual connections between the system components (or the process steps) may differ depending upon the manner in which the present invention is programmed. Given the teachings of the present invention provided herein, one of ordinary skill in the related art will be able to contemplate these and similar implementations or configurations of the present invention. 
     Having described embodiments for a mechanism and method for displaying a document differently depending on a context, it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings. It is therefore to be understood that changes may be made in the particular embodiments of the invention disclosed which are within the scope and spirit of the disclosure.
