Hi Gerald,

We've added provisional URI schemes "ibi", "ibi-" and "upn" to the registry:

https://www.iana.org/assignments/uri-schemes/prov/ibi
https://www.iana.org/assignments/uri-schemes/prov/ibi-
https://www.iana.org/assignments/uri-schemes/prov/upn

Registry: https://www.iana.org/assignments/uri-schemes

Per the designated expert for URI Schemes registry, we're also notifying the uri-review@ietf.org mailing list that this provisional registration has been completed.

Best regards,

David Dong
IANA Services Sr. Specialist
