摘    要:面向服务的计算是Internet环境下的一种新型软件架构理念,即通过集成分布的服务构建软件.面向服务建模是面向服务计算中的重要研究内容.一方面,面向服务的软件同传统软件一样,需要首先对应用需求进行建模.另一方面,面向服务的计算需要实现分布复用和快速集成,这对面向服务的建模提出了新的要求.文中提出一种基于全过程复用的面向服务的建模方法,即提出构建特定应用领域的本体系统,包含相互关联着的多个不同类型的本体.不同层次的软件资产关联到这些本体上,支持面向服务建模的不同阶段,包括应用框架建模、业务流程建模、合作模式建模以及组合服务建模等.当出现新的服务软件应用需求时,通过本体系统的引导复用软件资产,最后构造出服务软件模型.

关 键 词:面向服务建模  SOA资产  SOA资产复用  本体系统

Abstract:Service-oriented computing (SOC) is an emerging software architecture paradigm on Internet, which develops software by integrating services. Service-oriented modeling (SOM) is the essential task in SOC application development. On the one hand, like traditional software, service-oriented application also needs requirement modeling as the first principle step of its development process. On the other hand, distributed reuse and fast integrating in SOC ask distinctive features for service-oriented modeling. This paper proposes an extensive reuse approach for SOM, which utilizes a multi-facets ontology system supporting reuse of various SOA assets throughout the modeling process. The assets in hierarchical repositories are associated with the ontology system, which include application frames, business processes, collaboration templates, and services. The paper also presents an iterative modeling process, when new requirement comes up, ontology-guided reuse in each modeling phase is performed iteratively and finally a deployable service-oriented software model is obtained.
Keywords:service-oriented modeling  SOA assets  SOA asset reuse  ontology system
