PRESENTATIONS/DISCUSSIONS

Dictionary patterns

Drummond has worked on a wiki page with patterns for XDI dictionaries:

Drummond has also updated the following wiki pages accordingly:

• https://wiki.oasis-open.org/xdi/XdiDictionaryReqs

• https://wiki.oasis-open.org/xdi/XbnfRules

ABNF progress

Joseph has created a more complete version of the XDI ABNF that validates successfully in the APG parser:

Markus has added an experimental ABNF-based parser to the XDI2 code:

Markus has proposed changes to Joseph’s ABNF in the above message thread.

XDI Messaging and XDI Bindings contributions

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

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:
