XDI Policy and Connections

Let’s continue to discuss XDI connection requests, connection invitations, link contracts, templates, community contracts, requester contracts, etc.

Update from Vienna Deep Dive:

Dan has uploaded a new version of XDI Policy, and the first version of XDI Connections

Dan has uploaded a working document about community link contracts

Discuss different ways for an RA to receive a copy of a new link contract instance

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

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?)

Other topics:

Review what happens when a connection invitation is processed.

Template versioning - what if the Template Authority changes a template? How does this affect existing LC instances? Should versioning for LC templates be mandatory?

What do “deferred” connection requests look like, and how are they processed?

Collection of Documents:

Correlating message requests and responses
In the XDI Browser Binding, and in the case of “deferred” responses, how can a message request and response be correlated? Do responses need IDs that match the request?

This may have special relevance for XDI connection invitations and connection requests.

Will this be covered by the XDI Asynchronous Messaging spec?
Transactional integrity
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:

IIW Preparations
Let’s discuss what demos or other sessions we are planning for the upcoming Internet Identity Workshop.

NEXT CALL
The next call is next week at the regular time.
