action item review

<JacekK> ACTION: Terry to review last call of WSDL RDF mapping http://www.w3.org/TR/wsdl20-rdf/ by beginning of July [ONGOING] [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action01]

<JacekK> ACTION: EricP to review last call of WSDL RDF mapping http://www.w3.org/TR/wsdl20-rdf/ by beginning of July [ONGOING] [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action02]

<JacekK> ACTION: Rama to describe one-to-many mapping between elements and ontology terms using schemaMapping on a concrete SA-WSDL file [DONE] [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action03]

Issue 5: Multiplicity of modelReference value

Jacek: not many justification so far for multiple modelReferences
... one example proposed by Rama -> one to many

<ericP> [[

<ericP> Case b) one-to-many

<ericP> To address the case of 'fullName' element in WSDL/XSD mapping to multiple

<ericP> concepts in the ontology (title, first name, last name, middle name etc),

<ericP> the proposal would work as follows...

<ericP> ]]

Amit: example for multiple modelReferences based on policies and agreements

http://lsdis.cs.uga.edu/projects/meteor-s/swaps/

Amit: example based on multiple ontologies: Ws-Agreement ontology, Qos Ontology, Domain Specfic ontology

presentation at http://lsdis.cs.uga.edu/library/download/SWAPS-www2006-may17.ppt

here is the paper: http://www2006.org/programme/item.php?id=5022

Rama and Joel: Having multiple modelReferences will be helpful

JohnMiller: How can mutiple modelReferences be combined

Amit: consistency needed if annotated with same ontology
... consistency not needed if different ontologies are used

Jacek: Could the user choose which modelReference is appropriate?

Eric: What are the mechanics for specifying preference ?
... Versioning issues should be left to ontologies and not handled in WSDL

Amit: ok to defer issue

RESOLUTION: Issue 5 closed - Support multiple modelReferences as a list of URIs

<JacekK> ACTION: JacekK to open 2 issues: relation of multiple model references (1) and annotationContext (2) [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action04]

Jacek: are there use cases for annotation context

Laurent: my earlier example showed how two users can annotate using annotation contexts
... annotations from two users should belong to different pools

Jacek: why should annotations from people be viewed differently

Rama: anotation context will simplify the job of tools/clients

Jacek: How would client know which contextId is relevant

Joel: context may used for supporting different languages

Jacek: I always see only one owner of WSDL file
... are two annotations from same type system allowed on same element

<ericP> +1 to specific use case

Jacek: Lets discuss the issue of context at a later time
... Laurent to provide better motivation for context

<JacekK> ACTION: LaurentH to specify use cases for separating different annotations (for example optimizations) into different contexts/perspectives [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action05]

Issue 7: Combining multiple modelReferences and schemaMappings

Issue deferred to later time as it depends on resolution to issue 6

Issue 10: modelReference vs. category

Jacek: Holger proposed replacing category with modelReference

Joel: can someone give a proposal for the ontology?

<JacekK> ACTION: JohnMiller to propose a specific RDFS ontology for interface categories [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20060606#action06]

Issue deferred till completion of action

Issue 6: Clarification of SchemaMapping concept

Jacek: schemaMapping is at schemalevel but it specifies transformation of data
... URI used to point to mapping

JohnMiller: mapping to be XML based

RESOLUTION: schemaMapping describes mapping from instances of the schema to instances of the semantic model

Still need to discuss in which directions the mapping should be - lifting (upCast) and/or lowering (downCast)
