A Reference Model for Service-Oriented Domain Software

Component-based and Service Oriented Architecture(SOA) domain software engineering is considered as an effective and efficient approach to improve the productivity and quality of large-scale distributed software development.But,current SOA are concentrating mostly on high-level conceptual model,lacking concrete reference model to guide the practical development process.The construction process of domain system based on Web services software architecture is introduced.On the basis of the process,a Reference Model for Web Services-oriented Domain Software Architecture,named WS-DSARD,is proposed,and its some primary meta-elements,for example role,operation,service component and service component class,is depicted in detail.From the perspective of service component interaction and integration,compositional semantics of service components is described.This approach will be beneficial to successful service-oriented domain software practices.
