Hi! I believe all archetypes I have seen have fields constrained to "free or coded text" (not only "free text") giving you the option for either choice at template creation time.
In the AM (and thus also in ADL) the "free or coded text" means the class DV_TEXT which is a superclass of DV_CODED_TEXT, see chapter 5 of http://www.openehr.org/svn/specification/TAGS/Release-1.0.1/publishing/architecture/rm/data_types_im.pdf If I understand the model correctly it is then impossible to constrain any field to be only "free text" since DV_CODED_TEXT is always allowed where DV_TEXT is allowed. Best regards, Erik Sundvall erisu at imt.liu.se http://www.imt.liu.se/~erisu/ Tel: +46-13-227579 P.s. Just to minimize confusion DV_CODED_TEXT is used when you want to specify a code from a system like SNOMED CT or ICD.
