Place Ontologies as Services
Linked Data Finland
Contemporary Place Names
The place name registry based on Finnish Geographic Names data ("Paikannimirekisteri") from the National Land Survey is published as the Finnish Geographic Names dataset. It has also been available since 2008 as the ONKI Geo service, including some 800,000 place names in Finland.
Historical Place Names
The Finnish Spatiotemporal Ontology SAPO is available at the ONKI service.
Research on historical place names is continued in the National Gazetteer of Historical Places project. Autocompletion search on historical places with an option for adding new place name suggestions and displaying historical maps on contemporary map is demonstrated in the HIPLA service (work in progress). For more information about this initiative see the research project page.
