Re: A way to generate PK-strings or new blank nodes

Hello David,

Fabian - To be sure I understand what you are describing. You would do

One more time, you say exactly what I was trying to say :-)

I agree with that, so the best solution is certainly that SQL (and not
R2RML) adds such a feature (every vendor implements the feature, why not SQL
itself ?).

Have a nice day !
