Some notes on the workshop are taking shape:
A look at emerging Web security architectures from a Semantic Web perspective
Comparing OpenID, SXIP/DIX, InfoCard, SAML to RDF, GRDDL, FOAF, P3P, XFN and hCard
At the W3C security workshop this week, I finally got to study SXIP in some detail after hearing about it and wondering how it compares to OpenID, Yadis, and the other "Identity 2.0" techniques brewing. And just in time, with a DIX/SXIP BOF at the Dallas IETF next week.
