摘　　要：提出了基于SOA三层架构的嵌入式文件系统的实现方法。根据"需求—语义—服务"三层架构的设计思想,完成了文件系统整体设计思路和实现方案。需求层利用UML建模方法、Ontology建模工具Protégé及其推理插件pellet构建了文件业务系统的领域本体模型,从领域模型中提取出了文件系统常用的系统用例,基于此完成用例的实现流程图。语义层建立了"需求—语义描述—服务"的语义特征树,并采用OWL/RDF语言对语义特征树进行了形式语义描述。根据业务用例、用例场景、业务步骤的分析过程找出对应的原子业务即业务语义概念范畴内最小的业务单元;根据原子业务映射到相应的系统需求进行系统建模,并得到对应的原子构件集合;通过形式语义将场景步骤序列描述为由一系列原子构件的组合,完成"需求—语义—服务"三层SOA结构的嵌入式文件系统设计。The embedded file system was implemented based on SOA architecture.According to ＂requirement-semantics-service＂ three-layer architecture,the file system design and overall program was completed.The requirement layer built domain ontology model of files business systems using UML modeling,Ontology modeling tool Protégé and Reasoning plug-in pellet.The semantic layer established a semantic feature tree and described the form of semantic feature tree with the language of OWL/RDF.The corresponding atomic business was found based on the processing of business use cases,use case scenarios,business steps analysis.The system requirements were mapped according to the atomic business and the system model was built,then the corresponding set of atomic components was obtained.The sequence of scene steps was described as the combination of a series of atomic components using the formal semantics.
