Hi Daniel, We have been working on this from several perspectives. We have been mostly focused in providing terminology binding support for archetypes, and first efforts were focused in providing term and subset bindings via external terminology services (such as ITServer)
Lately we have implemented a Snomed expression syntax engine (for both parsing and executing) called SNQuery (http://snquery.veratech.es) and we are using it instead, as provides more flexibility. Having Snomed expression syntax queries as value bindings in archetypes allows to easily create queries for data validation ("this code should be an allergy" or "the text of this coded text should be one of the synonyms of the code") and data transformation (to have conditional data transformation functions such as "if the diagnosis is a cancer diagnosis then A else B"). We mostly use subset membership queries, but I assume that subsumption testing will be handy in archetype specialization definition (subsets in the specialized archetypes must be a subset of the ones in the parent archetype).
