Use Cases
Built for clinical precision, applied to every domain.
OpenEMPI began in healthcare, but its core engine is entity-agnostic. From patient identities to business listings — if a record has attributes, OpenEMPI can deduplicate it.

A proven entity-agnostic engine
OpenEMPI's metadata-driven architecture lets you define any record type. The same probabilistic engine that links patient records de-duplicates millions of business and retail listings.
A documented "Restaurant Entity Definition" is proof: swap the schema, keep the engine. Matching strategy, distance metrics, and review workflow stay exactly the same.
