MMI Registration Instructions

MMI Site Registration

We ask you to please request membership via email (due to excessive spam on the automated system, sorry!). Please send email to to request an account on MMI.  Please provide the following information to speed the process along: your name, a preferred account name, contact phone number (will be visible only to administrators), and your home institution, if any.  We will provide your account as quickly as possible, usually within 24 hours.

ORR (Ontology Registry and Repository) Registration

Registration on the ORR site is independent of the MMI site. To register there, you can use the Create Account link at the top of the index page, or go directly to the Create Account page. Once you are registered you will be able to log in and create, register, and edit ontologies.

Registration Help

If you have trouble with the registration process, you can contact us either through the MMI Contact Us page, or email directly to John Graybeal (graybeal (at) and Carlos Rueda (carueda (at) We will get back to you fairly quickly, usually within the same day.


We thank you for your interest in our site. Let us know how we can improve (or how you can help us!).
