However, these are far from what people have been expecting. There are still some important unsolved problems. Krüger et al. discuss how to use components to realize services, but do not tackle how to assemble services and describe quality of service. The project MAIS focuses on modeling multi-channel adaptive information systems based on services. The project group presents the meta-model provisioning perspective, which consists of descriptions of service functions and quality of service and so on. However, the concept interface is not used in the meta-model, and how service functions are described is not discussed. Some S0A models at higher abstract level have been presented, which lack essential details to apply these models. Many definitions of concepts or components of S0A relate to specific implementation technologies, such as Web technology or Jini middleware. Some specifications, such as BPEL4WS and WSCDL, are also for Web technology. However, Web technology can only realize some aspects of S0A. Moreover, there are some differences between the definitions of terms or in the understanding of S0A. For solving problems above-mentioned, this paper presents the S0A reference model that can be used to design S0A. The paper deeply discusses some concepts on S0A, and expatiates on the structure of the reference model and its service bus and meta-model for service contracts. Moreover, the paper presents the maturity model for evaluating serviceoriented architectures. The S0A reference model can be used as a guide for building specific S0A, and provide the foundation for stakeholders to understand S0A.

中文摘要：

在对当前的面向服务体系结构研究的基础上，提出了一种用于设计面向服务体系结构的参考模型，深入地阐述了有关概念.详述了参考模型的结构以及其中的服务总线和服务合约的元模型，并提出了一个用于评价面向服务体系结构的成熟度模型．该参考模型为进一步设计面向服务的体系结构奠定了基础．

英文摘要：

Recently, SOA plays a more and more important role in software research and software development. On the basis of the research findings on SOA, this paper presents a SOA reference model that can be used to design SOA. The paper deeply discusses some concepts on SOA, and expatiates on the structure of the reference model and its service bus and meta model for service contracts. Moreover, the paper presents the maturity model for evaluating service-oriented architectures. The reference model lays the foundation for building service-oriented architectures.
