Indicator (metadata)

Boolean value in metadata that may contain only the values true or false

In metadata, an indicator is a Boolean value that may contain only the values true or false. The definition of an Indicator must include the meaning of a true value and should also include the meaning if the value is false.

If a data element may take another value to represent e.g. unknown or not applicable, then a Code should be used instead of an Indicator, and the meanings of all possible values should be clearly defined.

The suffix Indicator is used in ISO/IEC 11179 metadata registry standard as a representation term.
