Almost exactly a year ago, I asked:
how can I use my own website as the authoritative source of my own FOAF and DOAP information while at the same time that information being available in directories for searching, rating, etc.
Well, it looks like O'Reilly's CodeZoo supports the DOAP part of this (discovered via Edd Dumbill)
I'm still no closer to a DOAP-Atom plugin for Leonardo. Any volunteers?
