ODE-SWS: A Semantic Web Service Development Environment

Web Services (WS) are software modules that perform operations that are network-accessible through XML messaging. Web Services in the Semantic Web, that is, Semantic Web Services (SWS), should describe semantically their structure and capabilities to enable its automatic discovery, invocation and composition. In this work we present a development environment to design SWS in a language-independent manner. This environment is based on a framework that defines an ontology set to characterize how a SWS should be specified. The core ontology of this framework describes the SWS problem-solving behaviour and enables the SWS design at a conceptual level. Considering this framework, the SWS development environment is composed of (1) a graphical interface, in which the conceptual design of SWSs is performed, and (2) a tool set, which instantiates the framework ontologies according to the graphical model created by the user, verifies the completeness and consistency of the SWS through instance evaluation, and translates the SWS conceptual model description into SWS (and WS) languages, such as DAML-S, WSDL or UDDI. This tool set is integrated in the WebODE ontology engineering workbench in order to take advantage of its reasoning and ontology translation capabilities

An Adaptable Service Connector Model 1

Abstract. The volatility of network environments requires service connections to adapt to changes of service resources and user requirements. In this paper, we treat service connections as individual components called service connectors and present an adaptable service connector model that adopts a role mechanism to adjust connections between services. A role is an abstraction of services with common functionalities. It offers a changeable connector structure, enables reconfiguration of service interaction and encapsulates changes in interacting participants, making service connections more adaptable.
