GAZ is an open source gazetteer constructed on ontological principles and led by Michael Ashburner.
GAZ represents places through their names using an ontological approach to promote semantic coherence. All entities in GAZ can be treated as instances of environments (see the ENVO repository).
Due to GAZ's large size, the OWL- and OBO-formatted files will not be hosted here for the moment. You can, however, download them here:
Please use the GAZ repository's issue tracker to post issues (such as new term requests), comments, and questions.
