Objectives that a client wants toachieve by using Web Services

Provide the formally specified terminologyof the information used by all other components

Semantic description of Web Services: - Capability (functional)- Interfaces (usage)

Connectors between components with mediation facilities for handling heterogeneities

Goals

• Ontological De-coupling of Requester and Provider • Derived from task / problem solving methods/domain model • Structure and reuse of requests

– Search– Diagnose– Classify– Personalise– Book a holiday

• Requests may in principle not be satisfiable• Ontological relationships & mediators used to link goals to web services

Mediation

• Heterogeneity … – For 1$ on programming, $5 - $9 on integration © IBM, Nelson Mattos– Mismatches on structural / semantic / conceptual / level – Assume (nearly) always necessary

• Description of role – Components that resolve mismatches– Declarative description of arbitrary web service

• Types of Mediation within Semantic Web Services: (1) Data: mediate heterogeneous Data Sources (2) Protocol: mediate heterogeneous Communication Patterns (3) Process: mediate heterogeneous Business Processes
