Technical Summary
The Concise Binary Object Representation, CBOR (STD 94, RFC 8949),
defines a "diagnostic notation" in order to be able to converse about
CBOR data items without having to resort to binary data.
This document specifies how to add application-oriented extensions to
the diagnostic notation. It then defines two such extensions for
text representations of epoch-based date/times and of IP addresses
and prefixes (RFC 9164).
A few further additions close some gaps in usability. To facilitate
tool interoperation, this document specifies a formal ABNF definition
for extended diagnostic notation (EDN) that accommodates application-
oriented literals.
Working Group Summary
Was there anything in the WG process that is worth noting?
For example, was there controversy about particular points
or were there decisions where the consensus was
particularly rough?
Document Quality
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type, or other Expert Review,
what was its course (briefly)? In the case of a Media Type
Review, on what date was the request posted?
