| 摘 要： | 关系型数据库和关联数据的概念模型都基于现实世界的实体、属性及其关系而构建,具备建立映射和实现转换的可能性。两者语义模式映射的重点是关联关系的构建与表达。开源软件D2R的映射语言,通过核心要素ClassMap、PropertyBridge及其属性,支持关系数据库的SQL实现,支持将关系数据库不同实体之间、同一实体内部及与外部数据的关联关系构建为RDF链接。

| Abstract: | The concept model of RDBMS and linked data builds on basement of real world entity,property and their relationships.So it is possible to build mapping between them.The core of semantic pattern mapping is to construct and express the linking relationships.The language of open source software D2R supports to execute SQL of RDBMS and transfers relationships between different entities,inside same entity and among outside data sets into RDF linkage through core language element ClassMap,PropertyBridge and their ... |
