AGENDA


1) IDTRUST BUDGET PROPOSAL

The previous proposal had some issues, so we'll discuss proposed modifications.


2) OPEN SOURCE PROJECT UPDATES

Mike Schwartz, Markus Sabadello


3) LITERAL CONTEXTS PROPOSAL

Drummond Reed posted updated versions of all 3 core XDI documents:

  http://lists.oasis-open.org/archives/xdi/201202/msg00007.html

The most significant update is the "literal contexts" proposal, in which all RDF literals are modeled with an XDI literal context. As explained in Drummond's message:
  1. This gives every literal in the XDI graph its own XDI address without using a cross-reference - simplifying navigation and XRI processing time.
  2. This makes it much cleaner to express and navigate XDI metadata, such as datestamps and versioning.
  3. This simplifies parsing and serialization, since all semantics describing a literal will be in the XDI subject identifying it, and every XDI literal (now called a "terminal") will have an XDI predicate consisting only of "!". (Note that Victor Grey has suggested another XRI delimiter character could also be used for this - he suggests ":").

4) NESTED ROOT CONTEXTS PROPOSAL

The revised XDI docs also show nested root contexts. As explained in Drummond's message:
  1. This provides a clean way to model the relationship of different local XDI graphs available at different XDI network endpoints for the purposes of XDI discovery.
  2. This shows how a single physical XDI server (such as an LDAP server, SQL database, NOSQL database, etc.) can implement a "multi-tenant" model where it can host multiple independent local XDI graphs yet still have them logically appear as part of the global XDI graph.

5) PROPOSALS FOR OPTIMIZING $GET - XDI QUERIES
