全国冰川编目空间数据库元数据标准参考The Federal Geographic Data Committee's (FGDC) Content Standards for Digital Geospatial Metadata (FGDC-STD-001-1998) 的标准，同时考虑EOS-HDF元数据格式的要求而制定。包括识别信息、数据质量信息、空间数据组织信息、空间参考信息、发布信息和元数据参考信息，共计50个字段。同时还包括数据备份和数据存储2个字段，用于记录数据的存储信息，实现利用元数据管理数据存储路径的功能。在应用方面，全国冰川编目空间数据库元数据不仅可以实现数据网上查询检索，方便数据建设与数据使用，还可以用来有效地管理数据资源，即实现全国冰川编目数据仓库中雪花模型的管理模式。

The establishment of the Chinese Glacier Inventory Database metadata standard references the Federal Geographic Data Committee's (FGDC) Content Standards for Digital Geospatial Metadata (FGDC-STD-001-1998). The metadata format requirement of EOS-HDF is also taken into account. The metadata standard include fifty fields which storage the data identification information, data quality information, spatial data organization information, spatial reference information, distribution information, and metadata reference information. Two data storage fields are added to record the data storage information, which can realize the management of data resource by using metadata. There are two metadata application cases, one is data resource query page based on the metadata and the other is data warehouse management model based on the metadata.
