Hi
I created a new function *static Node createFromN3( const QString& n3 )*. It
creates a Soprano::Node from an N3 String. I've *tried *to document it in
the header file, but I'm not too sure if it's correct (the documentation).
It would be nice if somebody could go through it, please.
The Patch had a base directory of *kdesupport/soprano/soprano/
