In your note to Pat, you mentioned using RDF. (06)
As Matthew mentions above, data base systems use a record with
multiple data elements to express a relation. Although this often
includes multiple binary relations, it also includes cases of ternary
and higher order relations. RDF does have awkward ways of
representing such relations, but a syntax that is not limited to
triples would be (imho) far better to use, especially when "targeting
less technical audiences." (07)
