Meeting notes and updates on the e-Science Link-Up Meeting

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
