Ontologies implemented in RDF(S), DAML+OIL, and OWL should be evaluated from the point of view of knowledge representation before using them in Semantic Web applications. Several language-dependent ontology validation tools and ontology platforms, such as OilEd with FaCT, can be used in order to evaluate RDF(S), DAML+OIL and OWL ontologies. This paper… (More)
SOA4All will help to realize a world where billions of parties are exposing and consuming services via advanced Web technology. The outcome of the project will be a comprehensive framework and infrastructure that integrates four complimentary paradigm-shifting technical advances into a coherent and domain independent service delivery platform: Web… (More)
The use of a Semantic Grid architecture can ease the deployment of complex applications, in which several organizations are involved and where resources of diverse nature (data and computing elements) are shared. This is the situation in the Space domain, with a strong demand of computational resources inscribed in an extensive and heterogeneous network of… (More)
The convergence of the Semantic Web and Grid technologies has resulted in the Semantic Grid. The great effort devoted in by the Semantic Web community to achieve the semantic markup of Web services (what we call Semantic Web Services) has yielded many markup technologies and initiatives, from which the Semantic Grid technology should benefit as, in recent… (More)
Web Services are interfaces to a collection of operations that are network-accessible through standardized XML messaging, and whose features are described using standard XML-based languages. Semantic Web Services (SWS) describe semantically the internal structure and the functional/non-functional capabilities of the services, facilitating the design and… (More)
The combination of Semantic Web and Grid technologies and archi-tectures eases the development of applications that share heterogeneous resources (data and computing elements) that belong to several organisations. The Aerospace domain has an extensive and heterogeneous network of facilities and institutions, with a strong need to share both data and… (More)
In this paper, we describe SGSDesigner, the ODESGS Environment user interface. ODESGS Environment (the realization of the ODESGS Framework ) is an environment for supporting both a) the annotation of pre-existing Grid Services (GSs) and b) the design of new complex Semantic Grid Services (SGSs) in a (semi) automatic way.
The convergence of the Semantic Web and Grid technologies has resulted in the Semantic Grid. The Semantic Grid should be service-oriented, as the Grid is, so the formal description of Grid Services (GS) turns to be a crucial issue. In this paper we present our approach for this issue. ODESGS Framework will enable the annotation of all the aspects of a GS… (More)
