A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Concise Binary Object Representation Maintenance and Extensions WG of the IETF.

        Title           : Packed CBOR
        Author          : Carsten Bormann

   The Concise Binary Object Representation (CBOR, RFC 8949) is a data
   format whose design goals include the possibility of extremely small
   code size, fairly small message size, and extensibility without the
   need for version negotiation.

   CBOR does not provide any forms of data compression.  CBOR data
   items, in particular when generated from legacy data models often
   allow considerable gains in compactness when applying data
   compression.  While traditional data compression techniques such as
   DEFLATE (RFC 1951) can work well for CBOR encoded data items, their
   disadvantage is that the receiver needs to unpack the compressed form
   to make use of data.

   This specification describes Packed CBOR, a simple transformation of
   a CBOR data item into another CBOR data item that is almost as easy
   to consume as the original CBOR data item.  A separate decompression
   step is therefore often not required at the receiver.
