got it. so essentially you're saying that if a field is some arbitrary table is defined as the concept 'heart rate', then it would inherit behaviors potentially including allowable values, ranges, display attributes, etc? basically like inheriting a shared property descriptor / field metadata?

does UMLS define any of this more advanced stuff, or does it just define the attributes (ie. datatype and synonyms) that I see in the example on that page?

is this a project that's actively being developed for 11.1?
