This document specifies content-related aspects of terminology database maintenance. It gives guidance on the content of terminological data collections, with emphasis on data quality evaluation.

This document gives guidance for modellers of concept entries who need to ensure interoperability and high-quality content. It aims to ensure that terminological data collections themselves meet high standards for design conformity with standards such as ISO？12620-1 and ISO？16642, data accuracy and performance. It outlines principles for assuring data quality (see ISO？9001) and evaluating terminological data collections for purposes of continuous improvement. This approach contrasts that of ISO？23185:2009, which focuses on the usability of existing terminology resources.
