Abstract Abstract
YANG Schema Item iDentifiers (SID) are globally unique 63-bit YANG Schema Item iDentifiers (SID) are globally unique 63-bit
unsigned integers used to identify YANG items. This document defines unsigned integers used to identify YANG items. This document defines
the semantics, the registration, and assignment processes of SIDs. the semantics, the registration, and assignment processes of SIDs.
To enable the implementation of these processes, this document also To enable the implementation of these processes, this document also
defines a file format used to persist and publish assigned SIDs. defines a file format used to persist and publish assigned SIDs.

Some of the items defined in YANG [RFC7950] require the use of a Some of the items defined in YANG [RFC7950] require the use of a

these identifiers are implemented using names. To allow the these identifiers are implemented using names. To allow the
