qualifier free text free text
reviewer media
A photo or video a reviewer attached to one review — its value is the asset pointer (a literal, the way media's value is the asset pointer); the bytes are a graph instance, never pooled. A qualifier of the review property, cardinality many (one review may attach several).
Reviewer media is free text, written for one product alone and never shared as a category.
It is a qualifier of review — it has meaning only inside a review statement, never on its own. It belongs with review to social proof — what buyers and critics say about it.
It is answered inside every review statement, not as a standalone question on a kind.
Answered inside every review statement — not a standalone slot on any kind.
