That doesn't really help. A shared ontology is the best way to provide a 
shared understanding of what connects entities. Nepomuk does this.

However, there is talk of supporting quadruples which allows multiple 
data to be stored in the database but from different sources. For 
example, let's say you have an mp3 and store LastPlayed date, but you 
have 2 media players that can do that on the desktop, you would want to 
make sure your application data is not overwritten by the other 
application right...
