Depends on what you want to do ;-) In the near future, the automatic bidirectional transformation for openEHR/CEN will be completed (when CEN works out what data types it is using). This will mean openEHR tools will be able to generate CEN structures automatically. It may be worth looking at the openEHR EHR Extract specification as well. This is not yet finished, but will offer significantly more power than the CEN Extract, while containing a CEN-like mode to act as a wrapper for CEN-encoded information. > In particular, is > it important to know the CEN13606 archetypes if working with openEHR > archetypes.

There is no distinction in HL7 that I know of between what we call archetypes and templates in openEHR. At the best, you would have to say that an HL7 template is like an openEHR template that is built like an archetype, i.e. no re-use of anything, just a single giant archetype built for the particular purpose at hand (which would normally make us call it a template...)...
