校园网格环境下基于分类元数据的服务描述方法

Services Description Mechanism Based on Classified Metadata in the Campus Grid Environment

为了达到服务共享、使各种不同服务之间具有互操作性,文章针对校园网格服务异构、分布、自治等特性,把RDF与XML相结合,对所有服务提出一种基于RDF/XML的无二义性的服务描述方法.对校园网格服务按照服务种类进行分类,以属性为中心,为每一类不同网格服务定义不同的基本属性,根据服务类别和基本属性定义统一的元数据标准,并以此为依据对该类服务进行描述.

For the purpose of services share and interoperation among different services,this paper puts forward a unambiguous service description method based on Resource Description Framework/eXtensible Makeup Language according to campus grid services′ features,such as isomerous,dynamic change and autonomious.The campus grid services are classified according to the service attributes,and then defied different basic attributes for each type of service.A unified metadata standard is dified according to the service type and basic attribute,and with which to describe the service.
