Finland's National Board of Antiquities ordered ontology work from the Finnish Terminology Centre TSK to update and supplement MAO/TAO – Ontology for Museum Domain and Applied Arts. The work started in the autumn of 2016.
MAO/TAO ontology is meant for describing the contents of the museum and applied arts sector, and it has been available since 2004. It was built in MuseumFinland and FinnONTO projects. In 2015–2016 the National Board of Antiquities added concepts into the ontology in cooperation with the Terminology Centre and experts of different museum sectors. In the autumn of 2016 ontology work is continued by updating the structure of the ontology and by adding new concepts.
MAO/TAO ontology is published in the Finto Service of the National Library of Finland.
