The HL7 Reference Information Model (RIM) is a reference model that defines a common set of classes and relationships used for representing the content of health care messages. It forms the basis of the HL7v3 standard.
This tool is an interactive browser for exploring the HL7 RIM classes. You can browse the attributes of each class and view their descriptions (purple links). The relationships between classes are displayed as light purple elements. The structure of classes is rendered as a TypeScript-like type definition. You can navigate to the referenced classes by following the blue links.
