PRESENTATIONS/DISCUSSIONS

Report from XDI editors subcommittee

https://wiki.oasis-open.org/xdi/XdiOneSpecs
https://github.com/OASIS-XDI-Technical-Committee/xdi-spec-docbook

The editors discussed the mechanism to which they agreed so that the XML Docbook files that are checked into Kavi. There has been a challenge to access browser-viewable versions of these spec documents due to the difficulty of maintaining stylesheet associations. The editors discussed adding an automatic pull mechanism so that browser-viewable versions of the XML Docbook files at Github, which are posted as PDF files stored in the OASIS Kavi system, would be available via the XDI.org web servers.

#ACTION: Markus will set up the automatic pull mechanism.

#ACTION: Peter will confirm how the stylesheet association mechanism works.

XDI-RDF

Peter and Hubert reported that they hadn’t decided on the name for the spec. Hubert has started a Word document that gathers and organizes the thinking they have done. They will continue to advance that over the holiday period.

Drummond said that he had another conversation with a partner company he is working with to answer questions about JSON-LD and XDI. He said he’d like to finish the short paper that he’s started explaining the challenges with the RDF graph model that the XDI graph model addresses so this becomes available as a resource when this question is asked.

ACTION: Drummond to finish this paper and post it.

Graph Model Structure

Drummond and Joseph have worked more on the GraphModelStructure wiki page and the tree view of node types:

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

Drummond did a walk-though review of all the syntactic constructs in the tree view to explain why they were needed. He used the analogy of the periodic table, which applied the underlying principles of atomic structure to figuring out all the possible elements. It makes it easier to see the common patterns across the different constructs.

Joseph and Drummond have been discussing the best way to present this information in the XDI Core spec. Joseph has created several matrices that take the “periodic table” approach to summarizing node types and the associated syntax. A snapshot of two of those approaches appears below, however it is not yet been brought current with updates Drummond made to the Graph Model Structure table.

Action items coming from this discussion:

#ACTION: Drummond and Joseph to review the additions to the table.

#ACTION: Joseph to update the matrices.

#ACTION: Joseph to update the proposed ABNF for the XDI Core spec.

Markus then shared some thoughts that on requirements for syntax and use of variables.
