Markus was at a conference in Vienna (European Workshop on Trust and Identity):
XDI/RDF
Hubert, Peter and Les have worked on “RDFify XDI”, i.e. using widely known technologies such as RDF, OWL, SPARQL, Linked Data, TriG to realize the XDI goals and principles.
Markus has worked on new content for the specs:
XDI Messaging: Definitions of $get, $set, $del, $add, $mod operations
XDI Binding: XDI Browser Binding

XDI Policy and Connections
Let’s continue to discuss XDI connection requests, connection invitations, link contracts, templates, community contracts, requester contracts, etc.
Open topics:
Review what happens when a connection invitation is processed.
What do “deferred” connection requests look like, and how are they processed? How do we handle cases where user interaction is required?
Template versioning - what if the Template Authority changes a template? How does this affect existing LC instances? Should versioning for LC templates be mandatory?
Topics discussed previously:
Discuss different ways for an RA to receive a copy of a new link contract instance
Challenge of correlating message requests and responses (see below)
Issue related to having multiple link contract instances based on one link contract template (how to algorithmically determine the address?)
Insight: A link contract instance may be used by many authorities that can satisfy a policy _expression_ (e.g. groups, roles, organization membership)
Insight: Just like there can be a connection invitation, there can also be invitations for any other operation, e.g. $get

We have discussed the topic of transactional integrity a number of times in the past without reaching a conclusion. This seems to now have new relevance in conjunction with link contract instantiation.
The following document has a section titled “XDI Message Transactional Integrity Notes”, let’s review and discuss:

The next call is next week at the regular time.
