Sorry, I meant to start a new thread, not hijack. Let me do it now. A couple more questions (by the way Leslies description was awesome and makes total sense).
Interfaces a) When creating a generic outbound or inbound interface with an extrernal system - do you build based upon the archetypes only - i.e. provide as many values possible? or your specializations? or is this all mute and we stick with HL7? Templates, as a collection for a use case. I looked out in Subversion but only see one out there: http://svn.openehr.org/knowledge/templates/dev/html/ b) Do templates or specializations or archetypes define workflow e.g. record results, based upon results collect additional information or not?' In the case were a doc just wants to replicate a paper form but not improve it would I build a template or stick with Archetypes? So implementing a form like this: http://home.cogeco.ca/~epiphany/FPDoctor-Perfect-Progress-Note-2.0.pdf thanks! Greg Caulton Boston, MA http://www.patientos.org
