RDF can be a good mapping mechanism, but the mapping itself has the same
benefits and issues no matter whether you use RDF, Topic maps, or some
home-grown mapping method possibly using xml.  Using a standard can give you
some advantages - standard tools and the possibility that someone else can
use your mapping - but does not really change the essential task.
