ISO Identifiers

How ISO Does It

ISO identifies things using the MD_Identifier object which includes a citation to an authority (namespace) and a code. These identifiers occur in a number of locations in the standard and as an element of every citation.

MD_Identifier
+ authority [0..1] : CI_Citation
+ code : CharacterString
