DECISION POINTS FOR THIS CALL

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

ABNF REVISIONS

After last week’s discussions about the JSON data model, Markus and Drummond have worked up an ABNF that reflects the JSON model but goes further to address a key missing feature that the JSON model did not address, which is the distinction between entities and attributes that was captured in the Context Functions proposal. This ABNF is in the latest comment on the ABNF discussion page:

    https://wiki.oasis-open.org/xdi/XdiAbnf/Discussion

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

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

Following is an example of the one revision that the proposed new ABNF requires in the syntax compared to last week’s consensus: that attribute contexts are enclosed in < > brackets and value contexts are enclosed in << >>  brackets.  An example of what this looks like for a set of 3 email addresses follows. In this example:

3 instances of an email attribute are listed first.

3 references to those 3 instances to provide ordering are listed second.

The final statement is the singleton syntax for an attribute: !< > . This allows a separate address to be used to declare a singleton.

JSON SERIALIZATION OPTIONS

Today (Thursday) Joseph and Drummond were able to meet and go over new options for the JSON serialization that could be more “developer friendly” by not requiring parsing of the subject/predicate keys in order to build an XDI graph object model (GOM).

Joseph will present an example of what the GOM could look like an how to serialize it.

MESSAGE PARAMETERS (MARKUS & DRUMMOND)

We will review the updated XDI Message Patterns proposal page including the Parameters pattern section.
