The Ontology Web Language for Services (OWL-S) is a “core set of markup language constructs for describing the properties and capabilities of Web Services in unambiguous, computer-interpretable form.” When fully realized, OWL-S will allow service providers or brokers to define their services based on agreed upon ontologies that describe the “real world” functions they provide. OWL-S was originally called DARPA Agent Markup Language for Services (DAML-S), and was created as part of the DARPA Agent Markup Language (DAML) project.
The goals of
The Semantic Annotations for Web Services Description Language (SAWSDL) Working Group released a Last Call Working Draft of Semantic Annotations for WSDL .
Semantic annotations can be added to Web Services Description Language (WSDL) components for use in classifying, discovering, matching, composing, and invoking Web services. Comments are welcome through 1 November. The group also released the First Public Working Draft of the companion Usage Guide .
Semantic Annotations for WSDL (SAWSDL) defines how to add semantic annotations to various parts
The formal specification of knowledge, which is also known as knowledge representation, is not new. Long before the Semantic Web knowledge representation has been part of several studies. Starting in the seventies AI-scientists startet to work on predicate logics for the formal specification of knowledge.
