基于语义网格的注册信息服务模型设计

THE DESIGN OF REGISTRY INFORMATION SERVICE MODEL BASED ON SEMANTIC GRID

作为下一代网络新架构,语义网格凭借其强大的语义分析能力及集合网格技术的特征,正逐步被人们认可和接受。尽管网格注册为发布、发现资源提供了用于存储和访问元数据的一些机制(如,元数据目录服务MDS),但是要将其扩展到语义网格上处理资源,这种注册机制还不够完善。因此将Web服务和元数据目录服务引入语义网格的资源管理的信息服务模型中,提出一个语义网格注册信息服务模型。定义该模型的信息模型和语义模型,以此得出语义推理结论,并给出具体的执行过程。

As a new network architecture of next generation, the semantic grid is acknowledged gradually with its powerful ability in semantic analysis and its characteristics of integrated network technology. Although it provides some mechanisms to store and access metadata for publishing and discovering resources, such as MDS （Metadata Directory Service） , the Grid registry is inadequate for dealing with domain - specific resources on semantic grid. A registry information service model based on semantic grid is presented by importing the Web service and MDS to information service model to enhance the resource management of the semantic grid. The paper defines its information model and semantic model, educes the semantic inference, and then indicates its implementation.
