Add data relation type
Equip an existing carrier or structured object with additional chosen data, when such compatible data exists. Use a construction junction when several independently meaningful inputs must coexist on the same carrier or interact compatibly.
Directed semantics
Every direct mAtlas edge is an authored source → target assertion of this type.
Machine-readable record
/data/latest/relation-types/add-data.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.
