The Finnish Collaborative Holistic Ontology (KOKO)
From the website:
The Finnish Collaborative Holistic Ontology is the general, aggregated ontology of the National ontology service ONKI. KOKO ontology has the General Finnish Ontology YSO as its top ontology and a variety of other domain specific ontologies extending its concepts into more detailed subconcept hierarchies. KOKO’s domain specific ontologies include initially MAO (cultural heritage), AFO (agriforestry), TAO (applied arts), VALO (photography), and other ontologies are being added to KOKO by ontology matching.
The idea of KOKO and the National Finnish ontology infrastructure is described in English and in Finnish in the articles and reports below.
The KOKO ontology is created as a part of the FinnONTO project.
If you are looking for upper ontologies, this is one.
