Catalog & data

Compatibility data

Definition

Structured "works with" or "fits" relationships between products, which agents rely on heavily because shoppers frequently ask compatibility questions by exact model or part.

Defined in The Agentic Commerce Glossary.

How else it gets framed

The same term carries different emphasis depending on the surface it’s used on. Both readings are correct.

Structured attributes that assert a relationship between a product and something outside it — another product, a device model, a standard, a size system, or a use case. Typical fields: works_with, fits, compatible_with, suitable_for, pairs_with, replaces.
