ISO/TS 29002-5:2009 specifies the data elements and a syntax for an
unambiguous identifier for an administered item. The identifier is
called an "international registration data identifier" (IRDI), as
specified in ISO/IEC 11179-5. An administered item is any registry
item for which administrative information is recorded. For the
purposes of ISO/TS 29002-5:2009, an administered item can be a concept
or concept information element in a concept dictionary. "Concept
information element" includes things such as terminology (terms,
abbreviations, definitions, images, symbols), assignment of a
concept to a class of similar concepts (the concept type), and
references to source documents.


ISO/TS 29002-5:2009 was developed as a common resource to provide a
level of interoperability between implementations of ISO 13584 and
ISO/TS 22745. Its use is not restricted to these standards,
however. It can be restricted through implementation profiles by
standards that reference it. It can also be implemented without
restriction.
