  "abstract": "YANG-CBOR (RFC 9254, \"Encoding of Data Modeled with YANG in the Concise Binary Object Representation (CBOR)\") defines YANG Schema Item iDentifiers (YANG SIDs), globally unique 63-bit unsigned integers used to identify YANG items. RFC 9595 (\"YANG Schema Item iDentifier (YANG SID)\") defines ways to allocate these SIDs using IANA registries.\n\nThe present specification employs these SID allocation mechanisms to allocate ranges of 100 000 SIDs (representation size 64 bits) to each holder of an IANA Private Enterprise Number (PEN) of a value below 1 000 000. Holders of PENs of values smaller than 100 000 are also allocated ranges of 10 000 SIDs (representation size 32 bits).",
