We're still right at the beginning of trust.  I think we can do some
trust with with WebID and FOAF over the course of 2011.  Maybe
bootstrap some of the existing tool chains too.

RDF tripes are global scope assertions.  Quads I guess, are triples
qualified with some provenance.  W3C is relatively light on SAML /
OpenID experts, so we're lucky to have a few people on the list with
that experience.  The WebID XG will be a good opportunity for everyone
to get up to speed, and liaise with other groups.

Best way, IMHO, to understand W3C from 50,000 ft is to read through
some of Design Issues


Philosophically I think it can be summed up by saying that the Web is
a Universal space (Universal does not mean unique) designed with
tolerance in mind.

If you skim one of these a week (pick at random), I think you can only
be blessed with deep insight, a really good understanding of what The
Web is about, and how we've only just started.
