Service-Oriented Architecture (SOA) and Semantic Web Services for Web Portal Integration

Service Oriented Architecture (SOA) is gradually replacing monolithic architecture as the premier design principle for new business applications with its inherently systematic nature and capability. I T requires investment of advanced architectural thinking into definition of services before any development of services or service consumers can begin. Earlier efforts of notable styles of SOA such as CORBA and XATMI have failed to be adopted as main stream projects because of demanding design process requirement with sense-making activities and even have been residing with the modern SOA or Web services middleware. Thus this paper aims in incorporating such sense-making design activities with the proposed semantic web service based architecture. This paper tries to tackle the above problem by proposing a service-oriented architecture for web data and service integration. Firstly, it proposes a service-oriented platform independent architecture and Secondly, it presents a specific deployment of such architecture for data and service integration on the web using semantic web services implemented with the WSMO (Web Services Modeling Ontology).
