Read below. It is interesting to read what you try to do. This is work (R&D in the 7th Frame Work) for the near future, I expect.

At this moment Archetypes are there to represent data and information that needs to be stored, retrieved and exchanged. Archetypes/templates are not designed, so far, to store, retrieve and exchange knowledge. It is a matter of R&D to be done in the near future to make it possible. We need this to use Archetypes/Templates in clinical pathways, case management and workflow. > > Another issue is about computation.
