Code (metadata)

In metadata, the representation term code refers to, and is used in the name of, data elements whose allowable values can be represented as enumerated lists. Each enumerated value is a string that for brevity represents a specific meaning. For example, for a PersonGenderCode the allowable code valid values might be "male", "female" or "unknown". To be compliant with ISO standards a value meaning or definition must also be associated with each code.
