    Yeah, it's called collaborative treasure hunting! E.g., UC Berkeley's
    Multivalent Document(MVD) JAVA applet Browser : Informed Web-Document
    Access through Shared Annotation Tracker

    MVD 1.0a3 is a Java applet, implemented in JDK 1.0.2:

    MVD tour guide, including a GIS viewer:

    Once you feel comfortable with the MVD applet, you can run it directly
    via the following examples:

    Since the bootstrapping process that Doug is advocating for the grand
    challenge for the next decade, "The Information Utility: Make it easy
    for everyone to store, organize, access, and analyze the majority of
    human information online", am wondering if UCB's Multivalent Document
    (MVD) Browser would be of any help for us to "improve on what we have
    now and would provide a tool with which we could experiment"?

    Apparently, the MVD browser has the ability to browse web objects with
    the associated annotations to enable users to share each other's
    digested information.

    ByungHoon Kang, a third year graduate student (510-642-8468, says:

    "Multivalent documents (MVD) represent an open, extensible,
    network-centric document model. Conventional documents are monolithic
    entities, generally of a particular type (ASCII, HTML, XML, PDF, scanned
    image files, RTF, word processor formats, etc.). To view, edit or
    otherwise manipulate such a document, you need a particular viewer or
    editor; moreover, functionality is limited by the nature of the
    particular format and associated programs.

    With MVD, you can, in principle, open and manipulate any document
    format. Moreover, functionality (including what document formats are
    supported) is completely extensible. If you want a new feature, you can
    add it yourself, and share the resulting capability with others. Also,
    because the architecture is intrinsically distributed, you can easily
    perform functions with MVD that are not readily available elsewhere.

    ... We have designed an annotation-tracking service using the MVD
    (Multivalent Document) model and developed a prototype for finding web
    objects more expeditiously through parallel collaboration, efficient
    sharing/storing/retrieving of annotation mappings using DB, and querying
    the annotations with various criteria such as keyword, author and base

    Collaborators can use the annotation tracker to track their
    collaborator's previous works and notes in hunting the treasure on the
    web. Since the collaborator can notice the existence of their
    collaborator's annotation through implicit retrieval when they browse
    the same document, the overlapped and redundant collaborative tasks are

    Also, ... "In the annotation viewer (MVD viewer), a user can query the
    annotation with parameters such as base URL, author name and keyword
    with menu driven methods. Query results are collected into the list
    window of the annotation tracker. The annotation tree viewer can be
    used to visualize the author list in a way where the history of the
    follow-up annotations is visualized in a tree format."
