The new ontology for traffic, Liikenteen ontologia LIIKO, has been published on the Finnish thesaurus and ontology service Finto. The ontology is built on the former Merenkulkualan ontologia MERO (ontology for seafaring).
MERO was composed by the Finnish Maritime Administration and the Semantic Computing Research Group SeCo as a part of the FinnONTO project (2003–2012). The Finnish Transport Agency and the Finnish Terminology Centre TSK launched a project to update MERO in 2016. During the project some 1 200 concepts related to road traffic were added in the ontology. The new LIIKO ontology, which was published in October 2018, contains mainly terms in Finnish.
