Georgi,

We have to be careful here, really. You are expressing but one "World 
View" (yours as expressed in the DBpedia data set schema) re. "most 
people don't care about structure,  they care about content.... "  :-) 

In my experience "Most People" end up putting very sophisticated demands 
on databases once they imbibe the value proposition. This has been the 
case in the past re. SQL DBMS technology and will be the case re. RDF 
based Linked Data, just a matter of time.


Thus, I would just qualify (or re-tag) the DBpedia Ontology as the 
DBpedia Schema.  Basically, echoing the sentiments in the meme that 
Richard started earlier.
