I read that DJ Adams was just playing with FOAF not too long ago, and at the time it made me want to dig into RDF more. But, work got busy and I promptly got distracted away. If anything, though, I could see something like FOAF being really nice as a start for this purpose. Of course, there's vCard, but I think it wouldn't be very hard to convert to it from FOAF. The universality and connectivity that RDF could bring to this seem terribly nice. Throw in periodic auto-refresh, either literally by scheduled re-query, or by pub/sub notification, and you've got a neat auto-updating address book just for starters.shortname=ooobhc
