The OpenAthens Discovery service is a universal discovery service - i.e. it is not limited to any single federation. For the end-user it provides a consistent discovery experience over all the resources that use it, reducing the relative attractiveness of less rewriting-proxies.

For service providers it provides a discovery service that works for as many SAML federations as the service provider is a member of - no need to maintain your own discovery service and no need to present potentially confusing choices to the end user.
