Charles, i underestand what you are sawing. But, i see that i could do the
same if i have tables and each relationships. If i have to make a foaf relationship,
i can have 2 tables, and one column of one table "says" if that field is
a friend-of-someone or a subclass or another property. 
I am doing my master thesis of my University, and i want to underestand
which are the advantages of using rdf and not other languages with database
relationships. My doubt comes, because, i read a lot of rdf docs and Jena
docs, but now, i have to explain why i choose rdf and show a system working
with rdf.

thanks a lot for your help,
p.d: sorry for my english, is not perfect.
