Gluu has also proposed an "OX UMA claim profile"; for more information, see the Third-Party Profiles page.
HIE of One
The HIE of One open-source project is run by Michael Chen, MD and Adrian Gropper, MD. It implements an UMA V1.0.1 authorization server, and supports dynamic client registration for resource servers and clients. HIE of One serves as an OpenID Connect relay to other OIDC services, such as Google and Twitter. This authorization server is meant to be deployed as a single instance per patient (user). It is licensed through GNU AGPLv3. Support information is available at the distro link.
HIE of One acts as a Health Information Exchange service but under control by the patient themselves. It is coupled in the same root domain URL with a resource server that acts as a patient-centered health record (NOSH ChartingSystem), although they are two separate projects. HIE of One allows the patient to control user-managed access to her resources served by NOSH ChartingSystem using a specific RESTful API (FHIR) for health-related information. This allows other third-party applications to take advantage of the patient's health-related information in a secure and privileged manner, governed by the user and not by another third party.
HIE of One is not in production at this time; fully working code is in GitHub and is used for current demonstration of how HIE of One is coupled with NOSH ChartingSystem for the above functionality.
This implementation leverages third-party OAuth and OpenID Connect implementations Google OAuth2, Twitter OAuth2, and mdNOSH (this is for demo purposes for physician single-sign-on, not federated).
