A model-driven approach for composing SAWSDL semantic Web services
Composing Web services is a convenient means of dealing with
complex requests. However, the number of Web services on the
Internet is increasing. This explains the growing interest in
composing Web services automatically. Nevertheless, the Web
services' semantics is necessary for any dynamic composition
process. In this article, we present an MDA approach to develop
and compose SAWSDL semantic Web services. To model Web
services, we use a UML profile which is independent of the
description standards. The SAWSDL interface files are generated
by using transformation rules. To model the behavior of a
composite Web service and generate its executable BPEL file,
we use the BPMN notation in a platform of modeling and
implementing business process. The main contribution of this
work is the easy and extensible solution to a model-driven
development of the semantic atomic and composite Web services.
