WSMeta

Abstract

Translate Article

With the increasing adoption of the web-services stack of standards, service-oriented architecture has attracted substantial interest from the research community which has produced several languages and methods for describing and reasoning about services. These languages cover many concepts ranging from individual services and their code generation from specifications, service semantics, service compositions and networks, economics and business aspects around service ecosystems etc. However, this abundance of specification languages has also resulted in communication difficulties between stakeholders and hinders tasks such as service composition, discovery and maintenance. The presented work is a step towards the unification of the specifications and different aspects of service systems using Model-Driven Engineering. We propose a generic and abstract web service meta-model called WSMeta, which has the ability to describe both operation-centric web services (WS-*) and data-centric web services (REST) and can be used in tasks such as service evolution analysis and service systems maintenance.
