RELATED APPLICATION 
       [0001]    The subject matter of this application is related to the subject matter in a co-pending non-provisional application by inventor Mac Murrett entitled “Creating a Text-Editable Web Page Using a Word Processor,” having Ser. No. 12/109,538, and filing date 25 Apr. 2008 (Attorney Docket No. APL-P6054US1). 
     
    
     BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to techniques for editing documents. More specifically, the present invention relates to techniques for sharing comments in web-editable documents. 
         [0004]    2. Related Art 
         [0005]    On-line networks, such as the Internet or World Wide Web (WWW), are increasingly popular forums for exchanging information and communicating with individuals and organizations. For example, many users publish their own web pages to keep in contact with their friends, colleagues and family members. 
         [0006]    Moreover, word-processing programs are also widely used to generate documents, which can include a wide variety of content, including text and images. Additionally, these programs provide advanced features, such as tools for integrating text with embedded images in a complicated framework or layout. 
         [0007]    Unfortunately, it is currently difficult to use a word-processing program to generate a web page that includes such advanced features because the word-processing program (or a related interpreter program) is typically needed to interpret the framework information in output files from the word-processing program, and this functionality is typically not included in web browsers. 
         [0008]    Additionally, it is often difficult for users to interact with a web page to provide comments or feedback on the web-page content. 
         [0009]    Hence, what is needed is a method and an apparatus that facilitates publishing documents without the above-described problems. 
       SUMMARY 
       [0010]    Some embodiments of the present invention provide a system that edits a document. During operation, the system shares the document as a webpage and receives, from the webpage, a comment for the document by a collaborator of the document. Next, the system updates the webpage with the comment and enables responses to the comment by other collaborators of the document from the webpage. 
         [0011]    In some embodiments, the system also merges the comment into the document. 
         [0012]    In some embodiments, the system also receives a response to the comment from one of the other collaborators and updates the comment with the response. 
         [0013]    In some embodiments, sharing the document involves receiving an export instruction from a publisher of the document and generating the webpage from the document based on the export instruction. 
         [0014]    In some embodiments, the system also enables responses to a native comment within the document from the webpage. In these embodiments, the native comment is created by a publisher of the document. 
         [0015]    In some embodiments, the publisher is associated with at least one of enabling the comment, enabling the responses to the comment, and enabling the responses to the native comment. 
         [0016]    In some embodiments, the document corresponds to a word-processing document, a spreadsheet, or a presentation. 
         [0017]    In some embodiments, the comment corresponds to a general comment, a floating comment, a cell comment, an image comment, or a text-based comment.

     DETAILED DESCRIPTION 
       [0024]    The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention. Thus, the present invention is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein. 
         [0025]    The data structures and code described in this detailed description are typically stored on a computer-readable storage medium, which may be any device or medium that can store code and/or data for use by a computer system. The computer-readable storage medium includes, but is not limited to, volatile memory, non-volatile memory, magnetic and optical storage devices such as disk drives, magnetic tape, CDs (compact discs), DVDs (digital versatile discs or digital video discs), or other media capable of storing computer-readable media now known or later developed. 
         [0026]    The methods and processes described in the detailed description section can be embodied as code and/or data, which can be stored in a computer-readable storage medium as described above. When a computer system reads and executes the code and/or data stored on the computer-readable storage medium, the computer system performs the methods and processes embodied as data structures and code and stored within the computer-readable storage medium. 
         [0027]    Furthermore, the methods and processes described below can be included in hardware modules. For example, the hardware modules can include, but are not limited to, application-specific integrated circuit (ASIC) chips, field-programmable gate arrays (FPGAs), and other programmable-logic devices now known or later developed. When the hardware modules are activated, the hardware modules perform the methods and processes included within the hardware modules. 
         [0028]    Embodiments of the present invention provide a method and system for editing documents. Documents may include, for example, word-processing documents, spreadsheets, presentations, and/or other documents that may be created using an office suite. As a result, the documents may be created and/or edited using document editors such as word-processing applications, spreadsheet applications, email clients, presentation applications, and/or graphics suites. 
         [0029]    More specifically, embodiments of the present invention provide a method and system for sharing comments in a document. The document may be shared as a webpage with one or more collaborators of the document. Comments for the document may be obtained from the collaborators through the webpage and/or obtained as native comments from a publisher of the document. The webpage may be updated with the comments to allow the other collaborators to view the comments and respond to the comments. Furthermore, comments and responses may be displayed using comment threads that allow multiple collaborators to discuss text, images, cells, pages, and/or other areas of the document. Finally, the comments may be merged into the document from the webpage to facilitate collaboration on the document and/or update of the document based on the comments. 
         [0030]      FIG. 1  shows a schematic of a system in accordance with an embodiment of the present invention. As shown in  FIG. 1 , the system includes a computing system  102  and a server  120 . The interaction between computing system  102  and server  120  may facilitate collaboration on documents and/or sharing of comments for documents, as explained in further detail below. 
         [0031]    Computing system  102  may correspond to an electronic device that provides one or more services or functions to a user. For example, computing system  102  may operate as a mobile phone, personal computer (PC), global positioning system (GPS) receiver, portable media player, personal digital assistant (PDA), and/or graphing calculator. In addition, computing system  102  may include an operating system  106  that coordinates the use of hardware and software resources on computing system  102 , as well as one or more applications perform specialized tasks for the user. For example, computing system  102  may include applications such as an email client, address book, document editor  104 , and/or media player. To perform tasks for the user, applications may obtain the use of hardware resources (e.g., processor, memory, I/O components, wireless transmitter, etc.) on computing system  102  from operating system  106 , as well as interact with the user through a hardware and/or software framework provided by the operating system, as described below. 
         [0032]    To enable interaction with the user, computing system  102  may include one or more hardware input/output (I/O) components, such as display screen  110  and an input device  114 . Each hardware I/O component may additionally be associated with a software driver (not shown) that allows operating system  106  and/or applications on computing system  102  to access and use the hardware I/O components. 
         [0033]    Display screen  110  may be used to display images and/or text to one or more users of computing system  102 . In one or more embodiments of the invention, display screen  110  serves as the primary hardware output component for computing system  102 . For example, display screen  110  may allow the user(s) to view menus, icons, windows, emails, websites, videos, pictures, maps, documents (e.g., document  1   116 , document n  118 ), and/or other components of a graphical user interface (GUI)  108  provided by operating system  106 . Those skilled in the art will appreciate that display screen  110  may incorporate various types of display technology to render and display images. For example, display screen  110  may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, a surface-conducting electron-emitter display (SED), and/or other type of electronic display. 
         [0034]    Input device  114  may function as the primary hardware input component of computing system  102 . Specifically, input device  114  may allow the user to point to and/or select one or more areas of display screen  110  using a cursor, highlight, and/or other visual indicator. Input provided by the user using input device  114  may be processed by the corresponding software driver and sent to operating system  106  and/or one or more applications (e.g., transaction application  104 ) as one or more actions. 
         [0035]    Input device  114  may receive user input through various methods, including touchscreens, touchpads, buttons, voice recognition, keypads, keyboards, and/or other input methods. In addition, multiple input devices may exist on computing system  102 . Operating system  106  and/or applications on computing system  102  may use the input from the input device(s) to perform one or more tasks, as well as update GUI  108  in response. Images corresponding to GUI  108  may be sent by operating system  106  to a screen driver (not shown), which may display the images on display screen  110  as a series of pixels. As a result, the user may interact with computing system  102  by using input device  114  to provide input to operating system  106  and/or applications and receiving output from operating system  106  and/or applications through display screen  110 . 
         [0036]    As mentioned previously, computing system  102  may include a document editor  104  that allows the user to create, view, and edit documents (e.g., document  1   116 , document n  118 ). For example, document editor  104  may correspond to a word-processing application, spreadsheet application, presentation application, graphics suite, and/or email client. Documents created using document editor  104  may include flyers, brochures, posters, emails, spreadsheets, presentations, letters, and/or catalogs. The documents may be stored locally (e.g., on a hard disk drive) on computing system in a document repository  112  that is accessible to document editor  104 . Alternatively, the documents may be stored in a location (e.g., server  120 ) that is external to computing system  102  and accessed via a network connection with computing system  102 . 
         [0037]    Document editor  104  may additionally facilitate document sharing and collaboration between the user and other collaborators. For example, document editor  104  may allow the user to send a document (e.g., via email) to the other collaborators, receive comments for the document from the collaborators, and update the document based on the comments. 
         [0038]    Document editor  104  may further enable online sharing of the document. In particular, document editor  104  may allow the user to share (e.g., publish) the document as a webpage with collaborators of the document. The layout of images, text, and/or other information on the webpage may further replicate the layout of the document as shown within document editor  104 . Moreover, changes made to the webpage may be incorporated back into the document. Online sharing of documents using webpages is described in a co-pending non-provisional application by inventor Mac Murrett entitled “Creating a Text-Editable Web Page Using a Word Processor,” having Ser. No. 12/109,538, and filing date 25 Apr. 2008 (Attorney Docket No. APL-P6054US1), which is incorporated herein by reference. 
         [0039]    In one or more embodiments of the invention, documents created using document editor  104  are shared as webpages using server  120 . Document editor  104  may generate one or more webpages (e.g., webpage  1   124 , webpage x  126 ) from each document and send the webpages to server  120  using a network connection with server  120 . The webpages may be generated in response to an export instruction from the user and/or another publisher of the document. For example, the user may generate an export instruction for publishing the first ten pages of a catalog as webpages to server  120 . Upon receiving the export instruction, document editor  104  may generate the webpages from the catalog and send the webpages to server  120  for viewing, updating, and/or commenting by collaborators of the catalog. 
         [0040]    In one or more embodiments of the invention, sharing of documents from document editor  104  is facilitated by a collaboration module  122  in server  120 . For example, collaboration module  122  may handle requests (e.g., HyperText Transfer Protocol (HTTP) requests) for the webpages corresponding to the documents from collaborators of the documents. Collaboration module  122  may also verify access privileges to each document prior to transmitting the webpage(s) for the document to the collaborator requesting the document. 
         [0041]    Furthermore, collaboration module  122  may allow collaborators to make changes to the webpages. For example, collaboration module  122  may receive comments for a document through the webpage(s) for the document. Collaboration module  122  may also update the webpage(s) with the comments to allow other collaborators to view the comments. Finally, collaboration module  122  may transmit the comments to document editor  104 , which in turn may incorporate the comments into the document. For example, document editor  104  may write the comments to a file corresponding to the document in document repository  112 . 
         [0042]    Those skilled in the art will appreciate that document sharing, export, and merging using webpages may be implemented in multiple ways. For example, webpages may be generated from documents in document repository  112  using collaboration module  122 , server  120 , and/or another component associated with document editor  104  and/or server  120 . Similarly, comments and/or other changes to the webpages (e.g., webpage  1   124 , webpage x  126 ) may be merged into the corresponding documents via pushes from server  120  or pulls from document editor  104 . Finally, webpages for each document may be provided to the collaborators using multiple servers and/or devices with network connectivity instead of a single server (e.g., server  120 ). 
         [0043]    As mentioned previously, changes to webpages on server  120  may include comments for documents created using document editor  104 . Each comment may correspond to a general (e.g., document-wide) comment, a floating comment for a specific page of a document, and/or a cell comment associated with one or more table cells of a document (e.g., a spreadsheet). Comments may also include an image comment for one or more images in a document and/or a text-based comment related to a selection of text within a document. 
         [0044]    Furthermore, as discussed in the above-referenced application, comments for a document may be provided through a web browser displaying one or more webpages pertaining to the document. For example, a collaborator on a document may provide a text-based comment by highlighting text within a webpage representing the document and typing the comment into a box associated with the highlighted text. Collaboration module  122  may then update the webpage and/or the document with the text-based comment so that the publisher (e.g., the user of computing system  102 ) and/or other collaborators may view the comment. 
         [0045]    Collaboration module  122  may also allow collaborators to respond to comments for a document. In particular, collaboration module  122  may allow a collaborator to provide a response to a comment for the document through the webpage for the document. Collaboration module  122  may then update the comment with the response in the webpage to facilitate discussion of the document. Display of comments and responses for documents is discussed in further detail below with respect to  FIGS. 2A-2D . 
         [0046]    For example, responses may be displayed in the webpage (e.g., in a box) below the comment in the order in which they were received. In other words, collaboration module  122  may display dialogues (e.g., conversations, threads, etc.) related to a particular part (e.g., a text selection, an image, a cell, a page, etc.) of the document from multiple collaborators within the webpage for the document. As with individual comments, the dialogues may also be merged into the document and used by the publisher to update the document. Furthermore, the publishing of such dialogues through a single source (e.g., the webpage for the document) rather than from multiple sources, versions, and/or files may facilitate the instantaneous retrieval and consolidation of comments by multiple collaborators, as well as the update of the document based on the comments by the publisher. 
         [0047]    Collaborators may also respond to native comments created by the publisher within the document. For example, the publisher may use document editor  104  to create a presentation. The publisher may also use document editor  104  to add a native comment to the presentation asking for input regarding the title of the presentation. When the presentation is exported to server  120 , the native comment is included in the webpage corresponding to the presentation for viewing and response by other collaborators of the presentation. 
         [0048]    Furthermore, the publisher may enable or disable online comments, responses to online comments, and/or responses to native comments by one or more collaborators of a document. More specifically, the allowance or denial of reviewing and/or commenting capabilities may be provided by the publisher in the export instruction for the document. For example, the publisher may use an export instruction to grant access to the webpage for the document to ten collaborators, creation of and/or responding to online comments to five of the ten collaborators, and responses to native comments to two of the ten collaborators. The publisher may also grant or deny other privileges to collaborators of the document, such as downloading of the document in one or more formats from server  120 , uploading of newer/updated versions of the document for sharing on server  120 , and/or other modification privileges associated with webpages on server  120 . Finally, the publisher may update access privileges to the document using document editor  104 , collaboration module  122 , and/or another component associated with the sharing of the document. 
         [0049]      FIG. 2A  shows an exemplary screenshot in accordance with an embodiment of the present invention. More specifically,  FIG. 2A  shows a screenshot of a web-based user interface for reviewing and commenting a document. As shown in  FIG. 2A , the web-based user interface is provided by a webpage  202  within a web browser. Furthermore, webpage  202  may be obtained from a Universal Resource Locator (URL)  206  by the web browser. For example, webpage  202  may correspond to a shared representation of a document (e.g., a catalog) located at URL  206 . As described above, the document may be uploaded to a server associated with URL  206  by a publisher of the document and provided as webpage  202  to enable reviewing and/or commenting by collaborators of the document. 
         [0050]    As shown in  FIG. 2A , webpage  202  includes a box containing a comment  208  and two responses  210 - 212  to comment  208 . Comment  208  is shown beside highlighted text in webpage  202 , indicating that comment  208  is a text-based comment. Furthermore, comment  208  may be created by selecting the text using a cursor  204  and inputting text (e.g., “This should be replaced with another word.”) into a box provided by webpage  202 . Comment  208  may also be updated with response  210  (e.g., “But why?”) and response  212  (e.g., “Because it is the wrong word.”) by selecting a button  214  (e.g., “Reply”) and entering text into another box provided by webpage  202 . 
         [0051]    As a result, comment  208  and responses  210 - 212  may be concurrently viewed by multiple collaborators of the document and updated with additional responses within webpage  202  as the responses are received. In other words, webpage  202  may facilitate the creation and consolidation of dialogues between multiple collaborators of the document while avoiding issues related to distributing multiple files for the document, obtaining comments from multiple locations, and/or synchronizing comments from multiple collaborators. For example, webpage  202  may allow a discussion related to the highlighted text to be opened by a first collaborator (e.g., “Stella”) using comment  208 . The discussion may then be updated by a second collaborator (e.g., “mtinsley”) with response  210 . Finally, the first collaborator may further discuss the highlighted text with the second collaborator by posting response  212 . 
         [0052]    New comments may also be added to webpage  202 . For example, image comments may be added by selecting one or more images in webpage  202 , text-based comments may be added by selecting one or more characters in webpage  202 , and/or floating comments may be added by selecting other regions of webpage  202 . Once review and/or commenting for the document is complete, the comments (e.g., comment  208 , responses  210 - 212 ) may be merged into the document to facilitated update of the document based on the comments. 
         [0053]      FIG. 2B  shows an exemplary screenshot in accordance with an embodiment of the present invention. As with  FIG. 2A ,  FIG. 2B  shows a web-based user interface for commenting a document. In particular,  FIG. 2B  shows a webpage  216  representing a spreadsheet document. Moreover, webpage  216  may be accessed by one or more collaborators of the spreadsheet to review the spreadsheet and/or submit comments for the spreadsheet. 
         [0054]    As shown in  FIG. 2B , webpage  216  includes two comments  218 - 220 . Comment  218  represents a floating comment in the spreadsheet. In other words, comment  218  (e.g., “Maybe a 3D chart would be better”) may be positioned within webpage  216  in a certain area (e.g., page) of webpage  216  without pointing to specific information (e.g., text, cells, images, etc.) in the spreadsheet. Responses to comment  218  may be provided by selecting a button  224  within the box containing comment  218  using cursor  204 . 
         [0055]    On the other hand, comment  220  (e.g., “Conditional format rules highlight scores below 60%”) corresponds to a cell comment related to a specific cell in the spreadsheet. Consequently, comment  220  includes an arrow to the cell within webpage  216 . Responses to comment  220  may be made by selecting button  222  using cursor  204  and/or another input mechanism (e.g., keyboard shortcuts), or by selecting the cell within webpage  216  using cursor  204 . Furthermore, responses to comment  220  may be related to comment  220  and/or the cell to which comment  220  points. As with  FIG. 2A , new comments for the spreadsheet may similarly be added by selecting cells, text, images, and/or other regions of webpage  216  and entering the comments into boxes (e.g., text boxes) provided by webpage  216 . 
         [0056]      FIG. 2C  shows an exemplary screenshot in accordance with an embodiment of the present invention. In particular,  FIG. 2C  shows a screenshot of a set of thumbnails  226 - 236  for a document. Thumbnails  226 - 236  may correspond to pages of the document and may allow the user to quickly access a specific page by selecting the thumbnail representing the page. As shown in  FIG. 2C , thumbnail  230  is selected, indicating that the user may be viewing the page associated with thumbnail  230 . 
         [0057]    Thumbnails  226 - 236  may additionally indicate the presence of comments within pages of the document. More specifically, triangles in the upper right corners of thumbnail  226  and thumbnail  230  are shown, signifying that thumbnail  226  and thumbnail  230  may include comments (e.g., native comments, online comments, etc.). The user may thus access comments for the document by selecting the thumbnails for pages that contain comments instead of browsing through the entire document. 
         [0058]      FIG. 2D  shows an exemplary screenshot in accordance with an embodiment of the present invention. The screenshot of  FIG. 2D  may correspond to a user interface for viewing and submitting general (e.g., document-wide) comments for a document. Furthermore, the user interface may be accessed through a document editor, such as document editor  104  of  FIG. 1 , or through a web browser and webpage associated with the document. 
         [0059]    As shown in  FIG. 2D , the document includes two general comments  238 - 240 . Comment  238  (e.g., “Please take a look at this document and see what changes need to be made.”) is provided by a first collaborator (e.g., “Stella Du”), while comment  240  (e.g., “Will do!”) is in response to comment  238  and is provided by a second collaborator (e.g., “mtinsley”). Additional general comments may be submitted by entering text into a text box  244  (e.g., “Click here to type a note”) provided by the user interface and selecting a button  242  (e.g., “Post Note”) below text box  244 . Alternatively, other types of comments for the document, such as text-based comments, image comments, cell comments, and/or floating comments, may be provided by selecting areas within one or more webpages representing the document, as described above. 
         [0060]      FIG. 3  shows a flowchart illustrating the process of editing a documents in accordance with an embodiment of the present invention. In one or more embodiments of the invention, one or more of the steps may be omitted, repeated, and/or performed in a different order. Accordingly, the specific arrangement of steps shown in  FIG. 3  should not be construed as limiting the scope of the invention. 
         [0061]    First, the document is shared as a webpage (operation  302 ). The document may correspond to a word-processing document, a spreadsheet, a presentation, and/or another document created using an office suite. To share the document, an export instruction may be received by a publisher of the document, and the webpage may be generated from the document based on the export instruction. Other parameters associated with sharing of the document, such as access, review, and/or commenting privileges by collaborators of the document, may also be obtained from the export instruction. 
         [0062]    Once the document is shared, comments for the document may be received (operation  304 ) from collaborators of the document. Comments may correspond to general comments, text-based comments, image comments, cell comments, and/or floating comments. If a comment is received, the webpage is updated with the comment (operation  306 ) and responses to the comment are enabled (operation  308 ). As a result, comments for the document may be viewed instantaneously from the webpage to avoid repetition, while responses to comments may be enabled to facilitate collaboration on and discussion of the document by multiple collaborators. 
         [0063]    Similarly, responses to comments may be received (operation  310 ) during the period in which the document is shared. The responses may be provided for native comments obtained from the document and/or for online comments obtained from the webpage. If a response to a comment is received, the comment is updated with the response (operation  312 ). In other words, the response is immediately accessible from the webpage containing the comment. 
         [0064]    To facilitate collaboration and discussion, comments and responses may continue to be received (operations  304 - 310 ) and used to update the webpage until commenting is complete (operation  314 ). As a result, multiple collaborators in multiple locations may discuss the document by providing comments and responses for the document to the webpage and viewing comments and responses from other collaborators through the webpage. If commenting is complete, the comment(s) and/or responses may be merged into the document (operation  316 ) for update of the document based on the comments and responses.
