Flood Control Information Metadata Theory and Its Application
The resource information of flood control system has some characteristics which include dynamic, diversity, multi-source, randomness and magnanimity. How to fast and accurately obtain the right information from mass information has become a very big problem for users of flood control system. To solve the problem of resource information development and utilization in flood control system, based on the bask theory of metadata, this paper studies flood control information metadata. Firstly, the definition range of metadata is extended to resource object at any level, and to focus on the metadata of resource information at different level in FCDSS. Secondly, the structure of flood control information metadata management system is built, which is based on multilayer network structure. Finally, the method of making all-purpqse menu and table is researched by using the above metadata theory, and the all-parpose mqniry module is designed, which can effectively integrate with FCDSS. The application of flood control information metadata can give cove support for the exchange of flood control information, and provide theoretical basis and information support for integrated management of FCDSS.
