    I've been hacking around for many, many moons these days, looking for the
    simplest way to be able to "draw" topic maps. Well, my latest hack seems
    pretty simple. Right now, a user can draw simple maps, then save them as
    XTM documents. Soon, it will be able to import XTM documents.

    A screenshot of it and a dump of its saved file can be viewed at

    When it's a bit farther down the road, I'll put it up in the cvs at
    http://nexist.sourceforge.net. At this time, I'm not even sure the XTM is
    correct. What's missing:
            representation of x,y location in the XTM document (likely to be some kind
    of <variant> object
            and/or layout engine that takes an imported map and decides where to
    locate the nodes

    In the end, I'd like to do something similar with Jazz (pan & zoom), but
    that's far too complex a project for the time being.

    I tend to think that whatever user interface an OHS will eventually have,
    we will likely plenty of graphics horsepower.
