"An archetype not based on a reference model is impossible (or at least pointless)." Erik Sundvall
Erik, I love this comment, it should be put up on the openEHR Web Site as the "Play of the Day". So many times I see people trying to use Archetypes without a RM, or even worse using openEHR Archetypes without using the specified underlying openEHR RM. Although the later is better than the former, it still causes major confusion and badly designed Archetypes that cannot be used for implementation. Heath
