I have
discussed this general attribute namespace problem with a bunch of folks over
the past few months. I found that there was general support for the idea of an
identity attribute namespace project. Especially if it could be community
co-created. I was even lucky enough to find some folks, like Mark Wahl and
others, who have volunteered to contribute to it. So we’ve started something
called Identity Schemas (http://identityschemas.org).
My hope is
that we could do the “carving out” project out in the open, on this
site. A kind of self-service notion. Anyone who needs to do some attribute name
mapping help themselves and do it there.

I like the idea of carving out a namespace which can be
used to organize things like metadata types, attribute types, etc. It would be
nice if the type had resolvable components such that the consumer can discover
exactly what type of object to expect back in the value.

Guess I should have said Paul's examples are URLs, I'm talking URNs.
Anyway, shortened question, shall we recommend the "starting" URN and
best practice for defining for Higgins implementors?

I suppose this is yet another potential "whatever the Context Provider
implementations wanna do" area but ... I'll ask anyway.
I'm considering the URI's we're using for Metadata Items. Have we
prescribed a recommended namespace prefix for URI's in Higgins? Shall we
recommend following the W3C recommendation for Namespaces in XML (http://www.w3.org/TR/REC-xml-names/)?
urn:higgins:idas: ...? Something else? Recommend nothing and hope
for no collisions?
Paul put out some samples for Context Ref URIs on the wiki but I'm talking
about URI's which a re only meant for unique identification (as for Metadata
Items), not also potentially resolvable resources (such as an LDAP directory).
