Semantic Registration in Taverna (Pinar Alper)

• Feta Architecture
• Ontologist (Chris Wroe) -> Ontology Editor -> DL Reasoner -> Classification (in RDF(S)) -> obtain classification -> Feta, PeDRo
• Store WSDL Descriptions (in special XML schema), then annotate, and give to Feta
• The ontology, classified, and the annotated wsdl are merged into a single graph
• Taverna Workflow Workbench issues "semantic discovery via conceptual descriptions" against feta ... a set of canned queries
• Feta Engine
• Feta Loader uses myGrid service onto and domain onto
• use Jena, e.g., to do RDQL queries, etc.
• Feta Data Model
• Operation (name, description, task, methhod, resource, application, hasInput : Parameter, hasOutput : Parameter)
• Parameter (name, desc, semantic type, format, transport type, collection type, collection format)
• Service (name, description, author, organizations)
• WSDL based operation is a subclass of Operation
• WSDL based Web Service is a subclassof Service (hasOperation : WSDL based operation)
• workflow, bioMoby service, soaplab service, local java code subclasses of Service and Operation
• seqHound service is an operation
