针对当前尚无能够以统一的查询接口形式支持高效查询检索的大数据资源描述模型的问题，通过扩展大数据分区管理模型的痕迹属性，引入扩展项泛函，以支持差异化大数据信息资源组织模式的构建。在此基础上，给出了支持大数据资源高效检索的倒排检索模式，并证明其远比遍历检索模式和层次检索模式高效。同时，给出了方言模式下的统一查询机制。目前，大数据资源描述模型已在住房和城乡建设部的信息资源统一规划和国家住房信息系统建设中取得了成功的应用。

Because there is no big data resource description model that can support efficient retrieval with the form of a unified query interface at present,this paper extends the big data partition management model′s trace attrib-utes,and introduces an extension item functional to support the construction of a differentiation big data information resource organization mode. On this basis,this paper gives an inverted retrieval mode for supporting the efficient re-trieval of big data resources,and demonstrates that it is more efficient than the ergodic retrieval mode and the hier-archical retrieval mode. Meanwhile,the uniform query mechanism is given under the dialect mode. So far,the big data resource description model has achieved success with the unified information resource planning and the national housing information system construction of the Ministry of Housing and Urban-Rural Development.
