INFRAWEBS BPEL-Based Editor for Creating the Semantic Web Services Description

摘要

INFRAWEBS project [INFRAWEBS] considers usage of semantics for the complete lifecycle ofSemantic Web processes, which represent complex interactions between Semantic Web Services. One of themain initiatives in the Semantic Web is WSMO framework, aiming at describing the various aspects related toSemantic Web Services in order to enable the automation of Web Service discovery, composition, interoperationand invocation. In the paper the conceptual architecture for BPEL-based INFRAWEBS editor is proposed that isintended to construct a part of WSMO descriptions of the Semantic Web Services. The semantic description ofWeb Services has to cover Data, Functional, Execution and QoS semantics. The representation of Functionalsemantics can be achieved by adding the service functionality to the process description. The architecture relieson a functional (operational) semantics of the Business Process Execution Language for Web Services(BPEL4WS) and uses abstract state machine (ASM) paradigm. This allows describing the dynamic properties ofthe process descriptions in terms of partially ordered transition rules and transforming them to WSMO framework.
