XDI Tutorial
Markus has completed Part 2 of the XDI Tutorial:
Drummond was ecstatic about seeing Part 2. His only feedback was for the diagrams to use the new notation format, which Markus had in fact done for Part 1.
PRESENTATIONS/DISCUSSIONS
Next Steps on Working Drafts
We will discuss the additions/corrections we want to make to produce XDI Core 1.0 Working Draft 02, including:
MIME types for serialization formats.
Formatting improvements.
Adding missing sections.
Equivalence Relations ($is, $ref, $rep)
Graph notation format
Improved Github merging process.
First, we talked about whether we can have a browser-ready version of the spec that can be referenced from the OASIS servers.
#JOSEPH will follow up with Chet to see if we can get a browser-ready version on OASIS servers.
We next discussed the division of the Equivalence Relations section between XDI Core and XDI Messaging. We agreed that the basic rules belong in XDI Core, and that the equivalence rules for operations belong in XDI Messaging.
We then discussed the graph notation format. Drummond said that he wants to include the information from the XDI graph model document front matter—he showed an example. There was consensus we should add this section. Joseph noted that we can include SVG graphics format.
#JOSEPH will review and make a recommendation about where the graph notation format definition section should go.
Drummond summarized that once we perform the action items above, we should be ready to publish Working Draft 02. Our goal should be to have Working Draft 02 be functionally complete.
The “Unauthorized $ref Problem” and “Unbounded $set Problem”
We have talked about these many times but not reached a definitive solution. Let’s review the approaches we have considered so far, with a special focus on the new authority-relative link contract patterns.
“Forwarding” of Messages by a Server
If the target peer root specified by a message does not match the peer root that is authoritative for the graph the message is sent to, the message can be “forwarded” to the authoritative server for the peer root. See the following two lines from the XdiMessagePatterns page:
#1: FROM <--from-peer-->/$set/<--from-->[$msg]<--msg-id-->
#2: TO <--from-->[$msg]<--msg-id-->/$is()/<--to-peer→DECISION POINTS FOR THIS CALL
None scheduled.
