KOKOaja
KOKOaja is a tool for combining an upper general ontology and a number of domain ontologies, all in SKOS-format, into a single whole. It builds a new set of concepts based on those found in the ontologies combining matching concepts into one taking care to assign always the same URI to the same concepts.
The main intended use for KOKOaja is in building the Finnish Collaborative Holistic Ontology KOKO.
