英文摘要	Metadata and its relative techniques have been widely used in distributed data resources management and sharing. According to the requirements of geosciences data sharing traditional metadata management models driven by techniques not suitable to geosciences clearinghouse thoroughly. Geosciences data supermarket idea is proposed referring to the supermarket's services features (e.g., open, quick, considerate, etc.). As the most important infrastructure in geosciences clearinghouse, Metadata Management System (MMS) technique structure is designed by this idea driven by user requirements. Designed MMS technique structure is composed of 5 parts, i.e., metadata publish model, storage model, query model, access model and security model. These models are integrated under the unified information flow of data sharing. With the development and application of this system in China National Scientific Data Sharing Network, it is shown that the MMS technique structure driven by users' requirements can provide rather high quality geosciences Information services than the traditional methods.
