Purpose: The ISO IS 18104 is intended for helping the nursing profession to integrate their terminologies into computer systems and into larger health care reference terminologies. One purpose of the standard is to map between different terminologies.

Method: This mapping was tested, using three terminologies that are relevant for nursing in the Netherlands. Concepts and terms where selected, and their equivalence was determined by experts, and next these were dissected.

Results: The dissection revealed that several concepts can easily be interchanged among the three example terminologies, while others cannot, or only for specific purposes.

Conclusions: The ISO IS 18104 fulfills this purpose very well and can be considered the gold standard for mapping of nursing terminologies.
