Subject: [Uri-review] [IANA #1273521] Registration request for "at" URI scheme

Hi Bryan, 

We've added provisional URI scheme "at" to the registry:

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

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,

Sabrina Tanamal
Lead IANA Services Specialist
