Drummond gave a new presentation he has developed that shows most of the core constructs
of the XDI graph model in a very simple Alice and Bob scenario.
***** NEWS & UPDATES *****
--- DRUMMOND LONDON TRIP REPORT
On Monday Drummond gave the Alice and Bob presentation on XDI at the Identity Day Forum
at London's Innovation Warehouse.
Yesterday Drummond co-lead the Tech track at the World Economic Forum Rethinking Personal
Data Tiger Team meeting in London. The focus of the discussion was PDRL (Personal Data Rights Language). The conclusion of the group was that PDRL should be implemented as an XDI dictionary of terms that are used for link contracts governing the exchange of
personal data. This takes advantage of three key features of XDI:
·
Link contracts - the binding of data to permissions
·
Contexts -- PDRL needs to be able to describe permissions that are context-specific
·
Extensibility -- Data types that can be covered by PDRL can be easily extended
Giovanni and Mike brought up the new OASIS OData TC. Mike has joined it.
Mike compared OData to a subset of XDI where it is just focused on standardizing REST architecture
for data exchange.
Giovanni said he had a concern about OASIS having two Technical Committees that are covering
closely related areas. This could be confusing to developers, and to OASIS members.
So Giovanni thinks we have an opportunity to establish a liaison between the two TCs. He
believes we should go for a true integration, not just members joining each TC.
***** DECISION POINT QUEUE REVIEW *****
We still need to complete the prioritization of proposals on the wiki. Drummond has added
a page to track issues that do not have full proposal pages yet:
We agreed that we need to categorize proposals by spec in order to help determine priority.
The category names will be:
·
CategoryProposalGraphModel
·
CategoryProposalSerialization
·
CategoryProposalMessaging
·
CategoryProposalDictionary
·
CategoryProposalDiscovery
·
CategoryProposalLinkContracts
·
CategoryProposalQueries
# DRUMMOND, MIKE to reorganize proposal pages to put them in these categoreis and clean
up the home page to just have links to the categories.
Mike proposed that the
TC group the latest proposals,
and move them to
the top of the list. His proposed prioritization is: (1) Graph Model; (2) Serialization (JSON) (3) Messaging (API); (4)
Link Contracts (5) Discovery (6) Query (7) Dictionary
Mike suggested and Drummond agreed we should extract any formal sections of The XDI Graph
Model document and turn them into proposals. This would include the ABNF and the notation format.
We agreed that the issues regarding serialization and data encoding must be prioritized.
# MIKE to publish a proposal on use of the data URI format to specify literal type.
Drummond poiinted out that multiplicity is a question that needs to be addressed for XDI
messaging.
***** DECISION POINT FOR THIS CALL *****
We decided not to try to make a specific decision on this call. Instead we spent the time
going over and categorizing the current proposals and pending issues, and discussing how best to proceed. The key points:
·
We should prepare and send email about proposal pages well in advance of each call.
·
TC members should review them in advance of the call so that the call can focus just on the technical questions,
merits, tradeoffs, etc. necessary to reach a decison.
The next call is next week at the regular time. Drummond will not be able to attend as
he will be flying home from London that day.
