Was thread with Subject: "[Cbor] CBOR tag range IANA allocation policy" Three notes to WG: #1: Specification Required includes Expert Review. Section 4.6 of RFC 8126. The only way to get Specification Required *without* Expert Review under the RFC 8126 framework is basically to have First Come First Served with a mandatory field in the registration template for the specification. In contrast, RFC 7049 provides a registration template where the specification reference is optional. #2: CBOR implementations need to be able to handle 64-bit tags, although they do not need to perform any mathematical operations on them. #3: The term "generically useful" is from Thiago's <mid:15044986.HgQyyibD5o@tjmaciei-mobl1>. ~~~~~ 9.2. Tags Registry IANA has created the "Concise Binary Object Representation (CBOR) Tags" registry at [IANA.cbor-tags]. The tags that were defined in [RFC7049] are described in detail in Section 3.4, but other tags have already been defined. New entries in the range 0 to 23 are assigned by Standards Action. New entries in the range 24 to 255 are assigned by RFC Required. New entries in the range 256 to 4095 are assigned by Specification Required, with an additional consideration that tags in this range be considered "generically useful". New entries in the range 4096 to 32767 are assigned by Expert Review. New entries in the range 32768 to 18446744073709551615 are assigned by First Come First Served. Designers developing or experimenting with tags privately are encouraged to use the range 9223372036854775808-18446744073709551615 by picking a random tag or block of tags in that range. However, there is no formal reservation of that range for any particular purpose, and a tag MAY be assigned there at any time consistent with the above policy. The template for registration requests is: o Data item o Semantics (short form) o (Optional) References to published specifications that describe the syntax or semantics of the data item. The references do not need to mention CBOR or this tag registration. In addition, First Come First Served requests should include: o Point of contact o (Optional) Description of semantics (URI) - The URI can point to something like an Internet-Draft or a web page. *END*
