| Implementation instructions | It is recommended to document a globally unique and persistent metadata file identifier. The global uniqueness of a metadata file identifier can be ensured, for example, by using a universal unique identifier (UUID) or by using the nomenclature <country code> _ <manufacturer> _ <product> _ <version> _ <theme>. The metadata file identifier is documented using the gmd: fileIdentifier element. |
Encoding example: Assinging the metadata file identifier using the UUID
