Semantic Web Services Objectives

• Mark Wilkinson
  • Create a list of datatypes representing the core datatypes for the WABI services
  • Create OWL Classes representing these datatypes
  • Documentation of SADI

• Luke McCarthy
  • re-code core SADI code such that services add predicates, rather than client
  • Study Paul Gordon's WSDL-2-Moby tool and map some WABI services to BioMoby? for practice
  • tweak Paul's WSDL-2-Moby tool to be a WSDL-2-SADI tool
  • create some WABI-SADI services

DECISIONS MADE

• Service provider will "decorate" input by adding a new predicate/object to the incoming data; this is no longer a client-side task
• Client must semantically-type their input data according to the OWL document describing the service provider's input
  • this allows the service to find the input nodes based on their rdf:type rather than having to reason-over the incoming data.
  • service provider will strip this rdf:type tag off of the data before sending it back to the client.
• Service providers must semantically-type their output data according to the OWL document describing their output such that the client can recognize the nodes that have been decorated by the service. Clients may chose (probably will want to) strip the rdf:type tag off of the returning data.
