Archetypes are the fundamental shareable specifications of clinical information we need to provide quality health care, and have been formally accepted as a European standard in 2007 (CEN 13606 Part II)and now being considered by ISO. Each archetype represents a whole, discrete specification which is as inclusive as possible, always in terms of the openEHR reference model. The reference model itself guarantees that the key attributes for information in health records (such as who, when and where) are already taken care of and do not need to be addressed in each archetype. Further, the reference model has 5 different entry classes which provide the attributes and structures required for all the different sorts of information stored in a health record. Helpful resources include:
