data concept¶
data element, class, value domain, data frame, message or interface dialogue defined, at a minimum, with an unambiguous identifier and a definition
Clause: 3.1.10.1
Note 1 to entry: In order to exchange a value corresponding to a data concept, more information than an identifier, a name and a definition can be needed. For a property, a data type is needed. Depending on the kind of property, other data elements such as unit of measure, and language, can be needed as well. The additional information can be given in the data dictionary, in a data specification that references the data concept or associated with the data themselves.
History note: Introduced in ISO/TS 14812:2022
