aggregate rating
The rolled-up rating a storefront shows on cards, facets and search — a numeral on a rating unit (4.3 stars). Cardinality one: a product's canonical aggregate. A genuinely consumed/imported fact, frequently present when the individual reviews are not (the rating count exceeds the review count), so a distinct home, not a rollup of the review host. The scale it is read against lives in the rating unit (consistent with the review rating). The realised number and count are the data layer's instances (L1). The individual reviews are a SEPARATE host (`review`, b55).
Aggregate rating is a measured figure.
It belongs to social proof — what buyers and critics say about it.
the bundle what travels with each aggregate rating
A aggregate rating is not a lone value — each statement is a self-correlating bundle, carrying its own:
asked by the kinds that answer it
49 kinds answer it, each for a single value. The same question can be reused by unrelated kinds — one meaning, many homes.
