@LuisLopezPi could be really interesting, in order to validate that the RDF you are creating in RML is valid, to load the output using RDFlib, so these small bugs will be identified faster (are two lines of code)

[LuisLopezPi]

The bug is fixed!

[LuisLopezPi]

But if I'm not wrong, I should have an input file to get the output right? @dachafra

[jatoledo]

@LuisLopezPi tries to validate with RDFlib. I have the same error but in this case with quotes.

RML uses Turtle, you can validate if the rules you are generating are well-formed in RDF
