摘要
地下水数据共享平台是一个分布式面向网络的系统。采用元数据集中管理、数据体分散存储的策略可以共享分布异构的地下水数据资源。基于RDF/XML框架定制地下水元数据,使得地下水元数据可以与其他元数据标准进行交换,同时可以方便地对其进行扩展。以元数据为核心,以数据汇交—数据查询—数据浏览下载为主线,设计了地下水数据共享平台的功能。在J2EE环境下,实现了地下水数据共享平台,其中空间数据服务采用空间服务元数据和ArcIMS相结合的方式实现。
Groundwater data sharing platform is a distributed system faced the Internet. Adopting the strategy of centralized management of metadata and dispersive storage of data-body, the platform can share distributed and different format groundwater data. Based on the RDF/XML framework, groundwater metadata are established which can exchange with other metadata standards. Furthermore, groundwater metadata can be expanded easily to satisfy application need. Taking metadata as the core, the platform is designed whose functions include submitting data, querying data, browsing data and downloading data and etc. Under J2EE environment, the platform is developed. Specially, the spatial data service is accomplished by combining the spatial metadata with ArcIMS services.
