I will make the top-level production statement-list instead of xdi-graph, since a statement list is only one way of serializing a graph, along with at least the graph tree serialization. We want to be able to think of graphs as graphs independent of serialization.

Good point.

 

I am going to genericize the Statement ABNF so that it can generate as many as possible of the serializations when paired with ABNF for the specific syntax of each serialization.

Good plan.

 

For the serializations that allow multiple objects per single subject/predicate, we need rules for statements with multiple objects. Drummond, could you let me know which of the statement types in the Statement ABNF allow multiple objects?

Contextual and relational statements (and their inverses) allow for multiple XDI objects. Literal statements allow only one XDI object.

ABNF

Joseph and Drummond gave an update on progress on the revised ABNF:

https://wiki.oasis-open.org/xdi/XdiAbnf/Discussion (see the 2013-04-22 comment)

After reviewing the current discussion proposal at a high level with Dan, Joseph agreed to move it to the main ABNF page for presentation at IIW next week.

JSON SERIALIZATION OPTIONS

Based on the decisions on last week’s call, several wiki pages were renamed or revised.

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

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

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

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

We reviewed the new serialization options and discussed the merits of the formats. Joseph took the following action items prior to Internet Identity Workshop:

# JOSEPH will:

1. Add a wiki page for the third JSON format (Parse).
2. Align the examples so that they are the same across all of the serialization format wiki pages (this will make it easy to do side-by-side comparisons).
