CIMPL (Clinical Information Modeling Profiling Language) is a specially-designed language for defining clinical information models. It is simple and compact, with tools to produce Health Level Seven (HL7®) Fast Healthcare Interoperability Resources (FHIR®) profiles, extensions and implementation guides (IG). Because it is a language, written in text statements, CIMPL encourages distributed, team-based development using conventional source code control tools such as Github. CIMPL provides tooling that enables you to define a model once, and publish that model to multiple versions of HL7 FHIR.

NOTE: HL7® and FHIR® are registered trademarks owned by Health Level Seven International, and are registered with the United States Patent and Trademark Office.

CIMPL is open source under Apache® 2.0 license, and free for public use.

CIMPL was created by the MITRE Corporation.

We can help your clinical modeling project! MITRE provides services to help non-profits develop open-source detailed clinical models. MITRE's FHIR team can provide informatics, modeling, terminology, HL7 standardization, and clinical resources to facilitate FHIR development. For an example of MITRE's work, see the mCODE Implementation Guide.
