Marcia, Karen A quick note: assuming that these display labels may be quite application-specific, and of less "important/preferred/standard/whatever" status, you may represent them using specializations of skos:altLabel. For instance aat-schema:aCommunitySpecificLabel (btw. I don't know what's like this in AAT--I thought they had a pretty clear distinction between preferred and non-preferred terms, cf. [1]) Antoine [1] http://www.getty.edu/research/tools/vocabularies/aat/about.html#info > Thanks, Marcia. It's great to have an actual example so I know I'm not just making this up. :-) > > kc > > Quoting "ZENG, MARCIA" <mzeng@kent.edu>: > >> Karen, >> I am just jumping into the discussion without reading previous discussed issues completely so please ignore if my comments may not be relevant.

Again, additional attributes may be defined in a specific implementation. >> The FRSAD model also provides for relationships between different types of entities and entities of the same type.
