I'm using the NepomukFast generated classes, because that's what the other
akonadi feeder agents do, but in NepomukFast::Resource setProperty is not  
declared.
Any ideas why and what to do?

If possible it would be probably good to use the NepomukFast classes for  
feeders,
as they might have to update a lot of data.

Also where exactly should I use addProperty and where setProperty?
In most cases, such as:
res.addProperty( Soprano::Vocabulary::NAO::hasSymbol(),  
Soprano::LiteralValue( Note::iconName() ) );

which I do on every update of a note,
using addProperty would end up in setting the same information over and  
over again, no?
