SWSA Meeting of June 29, 2004

Amit, Tim, Stuart, Mark  

(sorry, notes are very thin)

Amit will send ptr to METEOR-S demo this week. 
Amit will not be able to attend Aug meeting. 

In meteor, developer is involved in setting up abstract process model, then
tool can be used use discovery at runtime, and it does the input/output
binding, and calls BPEL engine.

Match includes QOS - generates ranking over whole process, not single
atomic processes.

A number of Eclipse-based tools will be made available. 
Annotation tool for WSDL-S (semantically annotated WSDL)

Amit talking to Bijan about semantics annotation of WSDL. 

IBM is submitting policy model WS Policy Framework to W3C - related to UGa QoS. 

M: What is the approach to adding semantics for BPEL in Meteor 

A: approach is to introduce hooks to ontologies into these languages. 

M: What about semantic mappings?

A: We had a 1996 observer project that addressed multi-ontology, but feel we must
take smaller steps with industry - get them used to the idea of semantic annotation first.

Amit I talked to Chief Scientist of Rosettanet. They are interested in SWS,
but want to see it introduced gradually. First introducing semantic annotation of service elements. 

M. Next big topic is the role of mapping and translation: what architectural supports will be needed?
How much of this should be left to future evolution of the Semantic Web itself?
How does METEOR address the issue?  
It seems so far not a lot. Schema matching used between WSDL parameter names and
ontology concepts to find suitable annotations. 

A: Mostly at the level of relating advertisements to service descriptions. 

M: We need to establish role for ontology mappings as part of semantic web if we are to enable
integration of services that were developed independently. It is critical for using discovered services.
