基于MapGIS数据中心元数据管理系统的研究与实现

Research and Implementation of the Management System of Metadata Based on MapGIS Datacenter

介绍了元数据的基本内容和MapGIS数据中心的基本概念;重点说明了基于MapGIS数据中心二次开发的元数据管理系统的基本思想与实现方案。

Management System of Metadata can realize the storage, input, output, edit of metadata and the synchronization of spatial-data and metadata for the purpose of the metadata sharing. Datacenter management is a resource manager which is used for managing multi- source heterogeneous data and is also called Data Warehouse. Datacenter is also an orderly collection of management function for the multi-source heterogeneous data and is called Function Warehouse. Datacenter features the development model of the Data Warehouse, the Function Warehouse and the Building System. This paper first introduces the basic content of metadata and the basic concept of MapGIS Datacenter,and then focus on the basic thought and the implement of the management system of metadata based on MapGIS Datacenter.
