Definition: A Reference Model is an information model which defines a rigorous and stable set of modelling patterns upon which the clinical models (i.e. archetypes) are defined. Modelling patterns defined in the CIMI reference model include a set of complex datatypes, information patterns (e.g. data, qualifier, state), and structural patterns (e.g. composition, entry, tree). All clinical models (i.e. archetypes) will be defined by constraining the reference model. The reference model is intended to be instantiated with patient data, which conforms to the constraints defined by the associated clinical model.
Reference Definition: A reference model in systems, enterprise, and software engineering is an abstract framework for understanding significant relationships among the entities of some environment, and for the development of consistent standards or specifications supporting that environment. A reference model is based on a small number of unifying concepts and may be used as a basis for education and explaining standards to a non-specialist. A reference model is not directly tied to any standards, technologies or other concrete implementation details, but it does seek to provide a common semantics that can be used unambiguously across and between different implementations.
