DAML-S, Service Markup for the Semantic Web
Seminar aus WI/IM: DAML-S, Service Markup for the Semantic Web.
Abstract: The world-wide-web, as we know it now, could become obsolete in the nearest future, because it seems that it is gradually changing into a semantic web. This new extension of the internet offers lots of new and interesting possibilities. Web agents should help us with our daily routines, which are supported by web-services. It is important, that they are able to perform specific tasks, currently performed manually by human beings, completely on their own. Such tasks include automated web service discovery, automated invocation, automated interoperation, automated selection and composition and automated execution monitoring. Therefore the services on the web need to be described in a language that machines can read and understand. DAML-S provides such a web service description, which describes what a service can do and not just how it does it. In this paper we focus on the description language DAML-S, how it is related to DAML+OIL and compare it to other description standards. In the main part of the paper we describe the semantics of DAML-S in detail. Furthermore we explain, how DAML-S can be used, by presenting an example of a typical web service.
