Marja,

Yes, I am familiar with RDF at a very elementary level but don't have a 
professional background,
is what I meant.

That was very useful and enlightening, thanks.  The reference therein 
R2O, an Extensible and Semantically Based Database-to-Ontology Mapping 
Language 
<http://www.cs.man.ac.uk/%7Eocorcho/documents/SWDB2004_BarrasaEtAl.pdf>
is even more so.  This makes me happier and less cranky ;-).

So the question in my mind become, what is a "good" database schema for 
representing tag data, so that naive tag databases can be coupled to 
knowledge based reasoning mechanisms using RDF with "relatively small 
pain".  Alternatively to what minimal ontology can both naive tag 
databases and sophisticated knowledge based formalisms commit. The 
expression in relational database terms should be compatible with 
existing web and non-web applications if possible, to allow greater uptake.
