The ontology files, readme and statistical information can be found and browsed in the ontology library. Because many of the ontologies make use of imports, we have "localised" ontologies by parsing them, resolving and parsing all imports, merging the main and imported ontologies together, and re-serialising the ontology, all using the OWL API. The original main ontology and the imported ontologies are saved in the "sources/".
Each localised ontology is assigned a unique ID and is companied with a hard link. All the hard links are stored here. In the readme, there is some information on all the localised ontologies--their IDs, ontology file directories, and statistics.
