Re: FHIR RDF ordered list preferences?

Another alternative is PROV-DICTIONARY:
http://www.w3.org/TR/2013/NOTE-prov-dictionary-20130430/

Lists are a special case of mappings, especially if you've already conceded
the use of explicit indices. Two possible benefits here are that a) it's
already part of an accepted standard (but is itself a W3C Note) and b)
supports change of these dictionaries over time.
