元数据标准及其在古生物数据库中的应用

APPLICATION AND DISCUSSION OF METADATA IN PALAEOBIOLOGY GEOBIODIVERSITY DATABASE

元数据(Metadata)是关于数据的数据,元数据标准在数据共享中有重要的作用。目前,元数据已越来越为人们所重视,许多国家已经发布实施元数据内容标准,并开发了许多元数据操作工具。通过对国内外一些元数据标准的研究分析,阐述元数据的定义、作用、意义和标准化问题,并介绍各相关领域的元数据标准的主要内容,从而为制定古生物学元数据标准提供参考。

Metadata are the data about data. Metadata play a very important role in data sharing. Many governments, companies, or organizations are tackling the development of metadata standards to foster the effective management of electronic records and other sources. Here we describe the definition, function, significance, and standardization of metadata, introduce some of the related content standard of metadata, and explore the possibilities of developing a palaeobiology metadata standard.
