A system for collaborative document annotation whereby notes (i.e. annotations) associated with a document, such as an image or text document, are stored in a notes database on a central notes server. 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 requests from one or more note client applications for creating, storing, editing and retrieving annotations related to specific documents stored on the notes server. On the client side, the notes client functions to display the document that the user wishes to annotate and provides the tools necessary to permit the user to create, edit, delete, retrieve and store notes. A synchronization process transmits the annotations generated by the user from the notes client to the notes server. In response, the notes server transmits back an acknowledgement along with any new notes that other notes clients may have posted since the last synchronization was performed thus enabling multiple notes clients to annotate a document asynchronously with respect to each other. When annotations are posted to the notes server by a notes client, the state of the annotation database is synchronized such that all other notes clients can retrieve the current, up to date annotations associated with a document.

Synchronizing/updating local client notes with annotations previously made by other clients in a notes database

A client/server system for reading, measuring and displaying color density of documents located on a remote file system accessed over a WAN such as the Internet. The color density information displayed corresponds to specific coordinates of documents that are located on the remote image file servers. The invention provides means for reading, displaying and recording color density measurements of original digital images located on remote image file servers rather than representations of these digital images stored on the user's local computer or LAN. A web server application on the server side functions to capture measurement requests from one or more client applications for measuring, sending, recording and retrieving color density measurements related to specific positions of specific documents located on an image filer server. On the client side a client software application functions to display the document that the user wishes to read color density information from and provides the tools necessary to permit the user to measure, send, record and retrieve color density measurements. Additional information regarding spot colors and position in a digital color book can also be displayed as requested by the user. Further, the user can record the results of the color density measurement by pressing an annotation button in the color densitometer window. In response, a note containing the color values is created and placed over the document.
