An archetype is a re-usable, formal model of a concept. An archetype is expressed as a computable set of constraint statements, on an underlying reference model (URM). Concepts that can be modelled using archetypes include weight measurement, blood pressure, microbiology results, discharge referral, prescription, diagnosis. CIMI archetypes will be represented as instances of the ‘Archetype Object Model’.
