At present, IOF is open and free to anyone to join and contribute. Going forward, IOF is working to form a self-sustaining, fee-based, member-driven organization so that the IOF ontologies can live, linkable, and remain open. If you are interested in participating in the effort to establish IOF, please submit your request below. The IOF boards will review and approve/disapprove your request. Upon approval, you will be added to the IOF General mailing list and provided view access to shared content. IOF will use your affiliated email address for verification and communication. However, a Google account may be needed, if your affiliated email is not serviced by Google. For your convenience, please visit this page to link your affiliated email identity with your Google account.
