The Fast Healthcare Interoperability Resources® (FHIR®) Implementation Guide (IG) Registry is a centralized repository or catalog that stores and organizes IGs, which are structured documents providing instructions for how to implement specific technical standards, usually in the context of healthcare interoperability. These guides often define how data should be formatted, exchanged, and interpreted to ensure systems can communicate consistently.
