> The Emotional Data Model (EDM) is an open protocol that defines a governed,
> schema-bound representational format for externalising affective context as
> a deterministic, model-agnostic data object.

EDM provides three implementation profiles:
- Essential: 5 domains, 24 fields (lightweight memory platforms)
- Extended: 7 domains, 50 fields (journaling, companion AI)
- Full: 10 domains, 96 fields (clinical, compliance, certification)

Artifacts are encapsulated in the .ddna envelope, a byte-stable container
providing canonical serialisation, integrity guarantees, and immutable
governance attachment.

EDM is not a diagnostic tool, emotion recogniser, or biometric system.
Artifacts are issued from explicitly expressed content only.

## Schema

Profile schemas (choose based on meta.profile value):
- Essential: https://github.com/emotional-data-model/edm-spec/blob/main/schema/edm.v0.8.essential.schema.json
- Extended: https://github.com/emotional-data-model/edm-spec/blob/main/schema/edm.v0.8.extended.schema.json
- Full: https://github.com/emotional-data-model/edm-spec/blob/main/schema/edm.v0.8.full.schema.json

## Reference Implementation

- edm-spec (MIT): https://github.com/emotional-data-model/edm-spec
  Canonical schema, validation, and examples.

- ddna-tools (MIT): https://github.com/emotional-data-model/ddna-tools
  Extract, seal, and verify .ddna envelopes locally. Canonical profiles (essential, extended, full).

- ddna-reader (MIT): https://github.com/emotional-data-model/ddna-reader
  Verify and inspect .ddna envelopes.

## Domains

The EDM Full profile defines 10 top-level domains (Essential/Extended use subsets):

- meta: identity and provenance
- core: narrative structure (anchor, spark, wound, fuel, bridge, echo)
- constellation: affective topology (emotion, archetype, relational dynamics)
- milky_way: contextual framing (who, where, when)
- gravity: salience and persistence (weight, decay, recurrence)
- impulse: motivational orientation (drive, urgency, directionality)
- governance: consent, jurisdiction, retention, and subject rights
- telemetry: extraction confidence and model metadata
- system: embeddings and compute boundary
- crosswalks: external taxonomy mappings
