IOF OWL is available in a number of RDF formats. These are available for offline use (i.e., download all of IOF as a zip), or online use. Each IOF ontology file is available for "follow your nose" treatment, a general description of which is available here.


IOF OWL is published in two releases:

  • IOF Production is published at the end of each calendar quarter and has been vetted by SMEs and passed standard industry hygiene tests for OWL.
  • IOF Development is published in real-time as changes are incorporated by the IOF Community and consists of a draft as well-vetted content.
