We do not have a road map for promoting this to production. There are a great number of items that need to be considered before making that determination. We still have several pieces that need to be resolved/modified before we can even consider a guaranteed production server.
Terminology will indeed be updated with our forthcoming LOINC release. Work on the server will continue next year. After that time we will have a better sense of a production timeline.
I hope this addresses your question. Please let me know if you have any other questions or concerns.
