<p>A system for collaborative document annotation (40) whereby notes or annotations associated with a document, such as an image or text document, are stored on a web server (54). The documents and associated annotations are treated independently from each other whereby separate data structures are created for the documents and for the associated annotations. A web server application on the server side functions to capture special requests from one or more client applications (42) for creating, storing, editing and retrieving annotations related to specific documents located in the server (54). A Notes Server (58) functions to log all annotation activities along with information about the corresponding clients (42) that create, edit and provides the tools necessary to permit the user to create, edit, and retrieve them. On the client side a Notes Client software application, that is implementable as a web browser Plug-In (44), functions to display the document that the user wishes to annotate and provides the tools necessary to permit the user to create, edit, retrieve and store notes. A synchronization process transmits the annotations generated by the user from the client (42) to the server (54).</p> |
