NIST SP 800-218A PS.3.1: Archive release files with versioned infrastructure tools, model selection rationale and training process records (Low)

What does PS.3.1 require?

In archiving the files and supporting data retained for each release, the organisation versions and tracks the infrastructure tools (pre-processing, transforms, collection) that support dataset creation and model training, retains the documented justification for selecting the model, and retains documentation of the whole training run, pre-processing steps and model architecture included. Models and their components may need adding to the organisation's asset inventories at this point.
