I'm adding an asset management system to Request Tracker for my paid job. It's great getting paid to code FSS!
In my copious free time, I'm recoding the topic (or category) hierarchy for Lampadas. I had a hard-coded two-level system, which wound up falling short of the Gnome requirements. I'm recoding it to support arbitrary depth.
Now we really need to adjust ScrollKeeper categories so they will support both Gnome and the LDP, and other projects. Right now, ScrollKeeper's enforced topic hierarchy is heavily slanted towards Gnome. It's understandable, since it started as a Gnome project, but it will limit its usefulness if we cannot come up with a set of categories that handles documents from other sources equally well.
