Hi Dave, As Thomas suggests, it does depend on whether you expect to be binding to a single term from the terminology
e.g. DNACPR decision in http://clinicalmodels.org.uk/ckm/#showArchetype_1051.32.185 in which case Dmitry's advice is correct and the Archetype Editor allows you to add bindings to any/all of the terms via the terminology, then term-binding tab. Not the nicest UI but you get there!! If the target needs to be selected from a list of possible options then Thomas's advice is appropriate. One issue is that we do not have good industry standard ways of defining these external refset bindings, though it looks as if FHIR might get some traction.
