    Cooperating sf projects is fine with me. To make that work, it seems to me
    that there will need to be some kind of core API around which all projects
    operate. That implies that there is a core project, and all the others are
    some kind of plugin or whatever. Heck! In some sense, it seems to me that
    NODAL would make the ideal core project since it deals with the data -- Good place to start, though there
    does not exist any software yet to play with. Acute "fire-em-up-itis" makes
    me want to look elsewhere.

    Nexist has a plug in architecture: you just write to a particular api, then
    drop the classes into a particular directory and add a reference to that
    new directory to an XML properties file and reboot the system. There are
    probably other drop-in architectures out there (Protege, Jext, and JEdit
    come to mind) that may be more refined than what I have written.

    Google "OHS license" and you will find lots of discussion on this topic.

    Privacy, authentication, etc, are all enormous issues. I'm inclined to
    start thinking about using one of the J2EE platforms (e.g. JBoss) as a
    starting point in order to inherit the necessary security tools. JBoss is
    LGPL, which means its license will not infect ours. Enhydra recently
    pulled their J2EE offering from open source because of licensing
    issues. There are several other J2EE platforms, including uPortal which is
    completely free. Grant Bowman has compiled a list of these projects at

    I knew that :-)
