Anatomy of an archetype

An archetype is a well-structured (formal) model of clinical content. Archetypes are designed to be used as a basis for structuring data eg building forms and building queries (xpath-like).

They are written in a language called the archetype definition language (ADL). ADL archetypes can be converted to xml.
