FHIR Core Library

fhir-core is a Python library providing an abstract base class for FHIR resource models and Primitive Datatypes, along with factories to create FHIR resource models and other complex datatypes. It is powered by Pydantic V2, ensuring data validation and efficient serialization/deserialization. This library is primarily developed to support the 'fhir.resources' library but can be used independently. As of March 2026, the current version is 1.1.7, with frequent patch releases.
