An analysis of other potential use cases suggested the interest of defining an independent, generally applicable mechanism. -Provenance verification by signatures incorporated in the YANG data elements can be applied to any data processing pipeline, whether they rely on an online flow or use some kind of data store (such as data lakes or time-series databases). The application of recorded data for ML training or validation constitute the most relevant examples of these scenarios. +Provenance verification by signatures incorporated in the YANG data elements can be applied to any data processing pipeline, whether they rely on an online flow or use some kind of data store, such as data lakes or time-series databases. The application of recorded data for ML training or validation constitute the most relevant examples of these scenarios. This document provides a mechanism for including digital signatures within YANG data. It applies COSE {{RFC9052}} to make the signature compact and reduce the resources required for calculating it. This mechanism is applicable to any serialization of the YANG data supporting a clear method for canonicalization, but this document considers three base ones: CBOR, JSON and XML.
