An OO based Semantic Model for Service Oriented Computing

The need for having interoperable systems despite the presence of heterogeneous platforms has resulted in tremendous growth and acceptance of Web services in recent years. This success of Web services technology is fueling research efforts towards generalization into a science for service oriented computing (SOC). However, beyond the basic publish-find-bind model there is not much consensus yet on what are the architectural building blocks of a service oriented architecture (SOA). In this paper, we present a semantic model for SOC that is based upon established and well proven techniques of object oriented paradigm

1 Introduction

Various programming models have been proposed in the past for building distributed systems. Among these some of the popular ones included CORBA, DCOM, and Java RMI etc. While DCOM and RMI lacked interoperability, CORBA was considered a heavyweight platform. Moreover, synchronous Remote Procedure Calls (RPC) was the predominant style of communication provided by them.
