***** PRESENTATIONS/DISCUSSIONS *****

--- ABNF FOR INNER LOCAL ROOT ADDRESSING

In a discussion this week, Markus and Drummond realized there was a very elegant solution to the question of how to address inside a cross-reference. There are several use cases for this, including being able to reference a literal value in an incoming XDI message for purposes of evaluating that value in a link contract policy _expression_.

This solution requires exactly one change to the XDI graph ABNF. See:

***** DECISION POINTS FOR THIS CALL *****

This week's decision queue is the following set of proposals:

--- EQUIVALENCE LINKS AND REFERENCE LINKS (DRUMMOND & MARKUS)

   https://wiki.oasis-open.org/xdi/EquivalenceLinks

This proposal has been updated to reflect the consensus to use two different XDI verbs - $ref and $is - to express two different kinds of equivalence.

Note also this paper referenced by Giovanni Bartolomeo:

   http://iswc2010.semanticweb.org/pdf/261.pdf

We are ready to move this into Last Call provided there is consensus on the call.

--- XDI POLICY _expression_ (DRUMMOND & MARKUS)

Following on the discussion on the last TC telecon, a formal proposal has been posted for declarative policy expressions (vs. the former proposal to use _javascript_ expressions):
