Canonical embedding relation type
Map one structure injectively into another by the standard structure-preserving inclusion or representation. This records a canonical copy, not necessarily literal set containment.
Directed semantics
Every direct mAtlas edge is an authored source → target assertion of this type.
Machine-readable record
/data/latest/relation-types/canonical-embedding.json provides this definition and the IDs of every direct relation of this type.
A path may traverse an edge backwards for connectivity, but that never reverses the authored source-to-target assertion.
