Report from meeting OWL-S people

2 presentations

-> http://lists.w3.org/Archives/Public/public-ws-semann/2007Jun/0008.html

the one about OWL-S in Z notation is not directly relevant for us, but may end up in suggestions for further work

John: why do they need formal semantics in Z while OWL-S already has formal semantics

JacekK: for verification that their model is not broken
... it helps discovering inconsistencies (it was done for WSDL)
... and for discovering the common subset of OWL-S and WSMO if they formalize both in Z

WSDL 1.1 schema problem

Rama and Joel confirmed the problem

JacekK: we may want to put the attr extension before input and outputs

Rama and Joel both confirm this works and fixes validation

-> http://lists.w3.org/Archives/Public/public-ws-semann/2007Jun/0009.html

JacekK: let's wait for Pierre&Richard answer
... to http://lists.w3.org/Archives/Public/public-ws-semann/2007Jun/0010.html
... it seems that we'll need to fix the order in the spec
... if the code generation tools don't work with that, we may tell people not to use schema validation

Joel: I just tested code generation and it works

Implementation status

JacekK: John, any news about Lumina ?

John: next week (?)

Future of the WG/SWS

JacekK: I've added items 6 (external annotations) and 7 (actual language recommendations for lifting/lowering schema mapping)
... anybody would like to try more concrete formulation of this?

John: I think it's an excellent thing to pursue

JacekK: I will keep it on the list with nobody assigned
... XML tools (XQuery/XPath) are not really practical with RDF/XML

John: SparQL is a nice thing for extracting from ontologies

JacekK: SparQL returns a flat structure
... you get things repeated in resulting rows
... a SparQL extension would be nice
