摘要
在分析关联数据概念内涵与构建原则基础上,阐述了数据网络理念、HTTP URI命名与存取机制、RDF资源描述框架等关联数据核心要素对于信息聚合所具有的基础性作用。在此基础上,进一步剖析基于URI复用与RDF链接的关联数据聚合机制,指出资源URI开放复用在聚合机制中所扮演的基础性角色,并分析了作为聚合核心的RDF链接所具有的不同类型与聚合功能。以此为理论基础,阐述了基于关联数据的馆藏资源聚合模式,包括馆藏资源关联数据化与图书馆关联数据链接管理两部分。其中馆藏资源的关联数据化通过URI命名机制、关联数据词汇集创建、馆藏语义描述与关联数据发布实现图书馆关联数据集的创建与发布,从而为馆藏资源聚合提供数据基础;而链接管理则通过多种方式在图书馆关联数据集与其他数据集之间构建RDF链接并进行动态维护,以此为桥梁将各种实体馆藏与虚拟馆藏聚合成为整体资源空间。
Based on the analysis of the conceptual connotation and construction principle of the linked data,this paper expatiates on the basic role of the core elements of the linked data such as the idea of data network,the HTTP URI naming and access mechanism,and the RDF resources description framework in information aggregation.On this basis,the paper further anatomizes the aggregation mechanism of the linked data based on URI reuse and RDF links,points out the basic role of opening and reusing resources URI in the aggregation mechanism,and analyzes the different types and aggregation functions of RDF links as the core of aggregation.Taking this as the theoretical basis,the paper expatiates on the aggregation mode of library collections based on the linked data,including the data conversion of the linked library collections and the linkage management of library linked data.Among which,the data conversion of the linked library collections is realized by URI naming mechanism,linked data vocabulary creation,library collection semantic description and linked data publication to implement the construction and publication of the library linked data set,which provides the data basis for library collection aggregation.The linkage management is realized by constructing RDF links and implementing dynamic maintenance between library linked data set and other data set in many ways,and it＇s used as a bridge to aggregate various physical library collections and virtual library collections into whole resources space.
