The Web Service Modeling Ontology (WSMO)
SWS-Lecture7.ppt (Size: 1.6 MB / Downloads: 54)
Current technologies allow usage of Web Services But:
Only syntactical information descriptions
Syntactic support for discovery, composition and execution
=> Web Service usability, usage, and integration needs to be inspected manually
No semantically marked up content / services
No support for the Semantic Web
Mechanized support is needed for
Annotating/designing services and the data they use
Finding and comparing service providers
Negotiating and contracting services
Composing, enacting, and monitoring services
Dealing with numerous and heterogeneous data formats, protocols and processes, i.e. mediation
Web Compliance
WSMO inherits the concept of URI (Universal Resource Identifier) for unique identification of resources as the essential design principle of the Word Wide Web
WSMO adopts the concept of Namespaces for denoting consistent information spaces, supports XML and other W3C Web technology recommendations, as well as the decentralization of resources
Strict Decoupling
WSMO resources are defined in isolation
Each resource is specified independently without regard to possible usage or interactions with other resources
Centrality of Mediation
Complementary design principle to strict decoupling
Mediation addresses the handling of heterogeneities that naturally arise in open environments
Heterogeneity can occur in terms of data, underlying ontology, protocol or process.
Mediation a first class component of the WSMO framework
