Canonical

The Canonical Data Model: pure abstract types shared across Elonn boundaries.

The Canonical Data Model defines the common information language used throughout Elonn.

Every dataset exchanged across an architectural boundary consists exclusively of canonical concepts defined by this library.

The Canonical Data Model is independent of:

Contracts compose canonical concepts.

Implementations consume contracts.

Only the Canonical Data Model defines canonical concepts.

The CDM is just a set of model definitions.

There is no "Service-owned canonical extensions" category. A concept a Service needs is either
Service-specific data inside an ordinary canonical structure (an Object's own type and
content, a Resource's own type and content — see canonical-structure-policy.md, Use) or,
once more than one Service needs it, promoted into the shared vocabulary here, Service-neutral,
the way Drawing Operation was promoted from Paint's own private mark format.
