Architecture · Data model
One material. Several facts. One traceable acceptance basis.
What an item is, where it came from, what it must meet, what proves it, what state it is in and whether it is accepted for a particular use are six different questions. The model keeps them apart and derives readiness from all six.
Conceptual model under validation before release. Field definitions, rules and relationships are provided to licence holders.
