Scope
NB/T 20418-2017 is the English-translated version of 核电电子文件元数据.
NB/T 20418-2017 is the Chinese energy industry standard on electronic records metadata for the nuclear power industry.
It sits under classification A14, with the documentation and information standards rather than with any plant system, and it addresses the descriptive data attached to electronic records so that those records can be identified, managed and kept over the long life of a nuclear project.
It is one of the bulkier documents of its batch, which reflects the number of metadata elements a records scheme of this kind has to define. The provisions are framed around GB/T 4880-1991, GB/T 7408-2005 and NB/T 20042-2011, the three standards it cites. Issued on 10 February 2017, it has applied since 1 July 2017.
