The ONKI Ontology Service was originally developed and published by SeCo in 2008, and maintaned after this as a national Living Laboratory. During 2013 the National Library of Finland built a permanent, stable, continuously maintained version of the ONKI idea, which has now been released as the Finnish Thesaurus and Ontology Service Finto.
The new brand name Finto can be seen as a tribute to the FinnONTO project during which the ONKI service and its ontologies were developed at SeCo in collaboration with a large consortium of Finnish organizations, including the National Library. The development of Finto has been funded by the Ministry of Education and Culture and the Ministry of Finance.
