Reference Implementations

IA2 group at INAF developed a GMS implementation based on OAuth2 access tokens (JWT). The implementation is currently used by several astronomical portals for authorizing resource access. In addition to the standard search API some additional endpoints and a UI have been developed. The service is written in Java and source code is available at https://www.ict.inaf.it/gitlab/ia2/ia2-gms

CADC ....

>

The CADC has been operating a GMS service since 2013. It is a critical component in the architecture as all authorization decisions are based on group membership. It is implemented with an LDAP back-end. The service has extended the GMS API to include mechanisms to allow users to create and manage their own groups and memberships.
