The Finnish Transport Infrastructure Agency, the Finnish Railway Museum and the Finnish Terminology Centre initiated together an ontology project in the beginning of 2020. During the project the organizations expanded the Traffic Ontology LIIKO with some 750 concepts related to rail transport. The structure of the ontology was also updated.
The expanded LIIKO was published on the Finto service in August 2021. It contains approximately 3 450 concepts with terms in Finnish. The concepts in the ontology relate to seafaring, road transport and rail transport.
