Can somebody please explain (in simple terms) what's the difference between
"all" and "truthy" RDF dumps? I've read the explanation available
on the wiki  but I still don't get it.
If I'm just a user of the data, because I want to retrieve information about a
particular item and link items with other graphs... what am I missing/leaving-out by using
"truthy" instead of "all"?
A practical example would be appreciated since it will clarify things, I suppose.
