All organizations based in Switzerland can apply for a custom PID prefix in the Swiss namespace managed by CSCS (21.17xxx and 21.T17xxx).
To apply for a custom PID prefix please send us a message explaining your needs. After approval, an agreement between your organization and CSCS will need to be signed.
Depending on you use case the PID entries can either be managed by a "super user" or by a number of users defined by your organization. In both cases the related keys will be made available by CSCS.
