# CIMI Reference Model

From CIMI

**Abbreviation:** CRM
**Definition: **The CIMI Reference Model is the Underlying Reference Model on which CIMI's clinical models (i.e. archetypes) are defined. This reference model defines a rigorous and stable set of modelling patterns, including a set of complex datatypes, information patterns (e.g. data, qualifier, state), and structural patterns (e.g. composition, entry, tree). All CIMI clinical models (i.e. archetypes) will be defined by constraining the CIMI reference model. The reference model is intended to be instantiated with patient data, which conforms to the constraints defined by the associated clinical model.
