Section on useing XFN, hCard, etc. to create a portable social network. I wrote about this idea over a year ago after a discussion we had at BarCampRDU 2006.
“July 18, 2007 – Villanova University announces VuFind, a next generation library catalog, is now freely available as Open Source software.” Looks very cool. I need to spend more time with it though. Update: I just checked out the demo. This is really nice. It employs excellent faceted search with a clean interface and incorporates first stages of some social tools.(tags: opensourceOPAClibrary2.0facetedfacets)
