***** DECISION POINTS FOR THIS CALL *****

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

--- MULTIPLICITY (DRUMMOND)

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

We had an excellent discussion on multiplicity. Drummond explained the fundamental reasons that multiplicity syntax is required. Bill said he has not had time to formally write up his proposal, but the essence is to use a {set}{member} pattern, where sets do not require special syntax and members of the set are identified with a $ prefix.

Drummond was intrigued by this idea as it could simplify the current multiplicity proposal.

# DRUMMOND to think about Bill's proposal to see how it could simplify multiplicity syntax.

Giovanni then showed how OData and W3C RDB2RDF are both addressing multiplicity. He showed examples of OData query syntax from one of their TC presentations:

•Requesting an Individual Entity by ID

•GET /v2/Catalog/Genres('Adventures') HTTP/1.1

•Requesting an Individual Property

•GET /v2/Catalog/Genres('Adventures')/Name HTTP/1.1

•Requesting an Individual Property Raw Value

•GET /v2/Catalog/Genres('Adventures')/Name/$value HTTP/1.1

He also noted the OData approach to query filtering:

GET /v2/Catalog/Titles?$filter= Name eq 'The Sting' HTTP/1.1

(from https://www.oasis-open.org/committees/download.php/46573/OData%20Overview%202012-7-26.pptx )

Finally the W3C approach to identify record with ID#7 in the table People they use:

http://foo.example/DB/People/ID=7

(from http://www.w3.org/TR/rdb-direct-mapping/ )

--- XDI ADD OPERATION (MARKUS)

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

Markus was not able to make the call so we will take this up in our next call.
