Notes taken by Jacek

Present: John, Emilia, Sven, Jacek, Reto, Axel, James, Ioan, Cristina,
Adina

Topic: D3.4 - Amazon use case

James: only minor changes - state signature introduced "concept" keyword
James: and some updates in the transition rules
John: are all listings validated?
James: yes, only choreography lacks as the validator has to be updated
James: unsure about the status of when WSMX will run this
John: we need a deadline
Axel: James should find out until next telcon when WSMX could have this use
case running

ACTION: James will find out until next telcon (Feb 1) when WSMX plans to have
the use case running

Axel: who are the reviewers?
Axel: I can review it but need 3 weeks for it, not just two
John: we should get someone from WSMX

ACTION: Axel to review D3.4 by Feb 10
ACTION: James to find a WSMX reviewer for D3.4


Topic: D14
John: the deliverable is in good shape, but how would you do the actual
invocation of the web services? Last answer I heard was "grounding", the
deliverable (section 3.3 or 3.2) should say that, with at least a one-line
summary and a link to the grounding deliverable
John: comment on section 4: the OU is working on orchestration in IRS, it
seems that in D14 you need something called "performative".
John: In orchestration, you invoke goals, and you want to enable these
invocations. 
Axel: I understand, ideally Barry should join us more actively
John: he will implement it by end of January, then he can show it to us
Axel: for example by presentation in the WSMO telcon?
John: will add it to the agenda of an appropriate meeting
John: is this deliverable now pretty much final?
Axel: newer suggestions are in a KWeb deliverable, will have to be added to
D14 - like non-determinism using choose construct etc.
Axel: but first we need to prove the model with some examples
James: I had problems modeling non-determinism in D3.4, as Amazon WSDL
doesn't expose faults
James: anyway, it seems we only have client-side non-determinism, we need
something like OR on the updates that the rules effect
John: we will have minor update, then ask Dieter about making it final
Axel: and then we open version 0.3 to include orchestration?
John: we need to see what Barry is doing


Topic: SPARQL
Axel: SPARQL is an RDF query language
Axel: there's a protocol on top of it as well
Axel: but apparently there are concerns about SPARQL following the RDF
semantics
Sven: but SPARQL is very simple, some parts seem to be missing, like nested
queries; I might know by the next telcon
Axel: we might postpone the topic and tell Martin, who raised the issue, to
come to the next telcon - and should it be WSMO or WSML WG?
John: OK, postponed

SPARQL discussion postponed to the next telcon

Meeting adjourned, we'll meet in 2 weeks
