Technical resources
Everything you need to evaluate, integrate, and operate OpenEMPI in your data environment.
Start here
Different evaluators need different first reads. These paths keep the evaluation focused without creating thin topic pages.
Executives
Start with Use Cases, then Contact.
Confirm the business fit, flagship healthcare use case, and commercial evaluation path.
Integration engineers
Start with the Product technical brief, then public documentation.
Review matching methods, distance metrics, APIs, and standards-oriented integration options.
Procurement teams
Start with Contact.
Share deployment context so the team can prepare the right commercial next step.
Evaluation topics
Short definitions for the concepts most evaluators ask about before reading the technical brief.
Record linkage
Finding records that refer to the same real-world entity across one or more systems.
Entity resolution
Grouping linked records and supporting a trusted identity view for downstream systems.
Master Patient Index
The healthcare flagship use case: resolving duplicate patient identities across systems of care.
Deterministic matching
Rules-based matching that uses exact or configured conditions to classify records.
Probabilistic matching
Weighted field comparison that scores agreement and disagreement patterns across records.
Blocking
Candidate generation that keeps matching efficient by comparing likely pairs first.
Human review
Stewardship workflow for uncertain matches that require field-level evidence and judgment.
