Ownership and provenance
field_owner, source_system, source timestamp and conflict resolution.
A canonical internal record reduces repeated mapping work, but the defensible value is in ownership, lifecycle, schema change detection and traceable failures.
The canonical model is an internal normalization layer, not a new proprietary transport standard. Adapters should follow relevant open and emerging specifications.
field_owner, source_system, source timestamp and conflict resolution.
schema_version, mapping_version, contract tests and provider interface diff.
correlation ID, mapped payload, validation result, retries and dead-letter owner.
Idempotency, asynchronous states and human review before a risky retry.
Map the data, name the owner, define the evidence and decide what to test before implementation.
