Motivations
• Semantic Web is about to leave pure research and slowly picked up by industry
• More research is needed, but most of the fundamental technology seems to be there.
• Integration of the fundamental technologies is the main challenge
• The thesis proposes an integration of Semantic Web, Semantic Web Services and Agents. A roadmap for an integration of those three technologies are described.

Semantic Web – today (state of art)
• Semantic Web Stack development:– Lower layers are mature in the context of
research, i.e. XML, RDF, Ontology, ...
• ”The hen and egg problem” in practical use.

Semantic Web Services – today, tomorrow and future2005/6 Standards
WSMO SWSF WSDL-S OWL-S
Description WSMO (Web Service Modeling Ontology) has been developed since 2002. Part of a larger framework (together with Web Services Modeling Language and Web Services Execution Environment)
SWSF (Semantic Web Services Framework) is an effort by Semantic Web Services Initiative (SWSI). The first meeting of SWSI was held in December 2002. SWSF uses DAML-S draft as a starting point.
WSDL-S is being developed in METEOR-S project. The main purpose of WSDL-S is to extend existing WSDL standard with semantic description.
OWL-S is an OWL-S is a OWL-based Web service ontology and research effort started in May 2001 as DAML-S. In November, 2003 the language was renamed to OWL-S. Current specification 1.1 dates to November, 2004.
Developers Digital Enterprise Institute (DERI)
Language Committee of SWSI
IBM and University of Georgia.
Many companies and universities working in DAML program.

SEnSE: Short description
• SEnSE will provide an environment where– Users can delegate change tracking tasks to
software agents that proactively monitor the evolution and changes of design artefacts (tools)
– Notifications can be based on the semantic structure of documents / resources rather than simple version changes
– Information about changes can be done for indirectly relevant artefacts (tools) as well
