ONKI (Finnish Ontology Library Service)
From the website:
The ONKI service contains Finnish and international ontologies, vocabularies and thesauri needed for publishing your content cost-efficiently on the Semantic Web. Ontologies are conceptual models identifying the concepts of a domain. They contain machine “understandable” descriptions of the relations between the concepts.
ONKI is published and maintained by Semantic Computing Research Group SeCo. It is part of the on-going project to build a national semantic web infrastructure to Finland (FinnONTO).
Collection of ontologies/vocabularies, some of which will be familiar, others, perhaps less so.
Searchable ontologies/vocabularies and in many cases, downloadable.
