## Canonical data requirements

- Stable identifiers for entities, observations, tasks, products and events.
- Explicit units, coordinate reference, timestamps/time scale and uncertainty.
- Schema/semantic version and compatibility behavior.
- Source/provenance, confidence and processing lineage.
- Handling/releasability/retention metadata and object-level access controls.
- A compact event form plus artifact reference for large imagery, video or datasets.

## Versioning rule

Prefer backward-compatible additive changes. Breaking changes require a new schema/semantic version, a transition period or adapter, explicit migration tests and release notes identifying affected producers and consumers.
