摘　　要：为将语义网技术与空间信息目录服务(catalog service for the web,CSW)相结合,提出一种语义支持的空间信息目录服务实现方法。构建本体实现空间信息的语义描述;扩展现有空间信息目录服务模型,支持空间数据与服务的语义注册;构建语义代理实现语义支持的空间信息元数据查询。服务原型系统的实现结果证明:该方法能有效地提高空间数据与服务的发现能力,简化查询步骤。In order to combine the semantic web technology with the spatial information catalog service for the web(CSW), a semantic-supported spatial information CSW implementation method is proposed. Ontology is constructed to realize the semantic description of spatial information;the existing spatial information CSW model is extended to support the semantic registration of spatial data and services;semantic agent is constructed to realize the semantic-supported spatial information metadata query. The implementation results of the service prototype system show that the method can effectively improve the discovery ability of spatial data and services, and simplify the query steps.
