If you want to create a new pathbuilder, click on "add Pathbuilder" in the pathbuilder overview. Then enter the name of the new pathbuilder, here e.g. "Normdaten".
Then you have to select the adapter or in this case the location where the triples, which are recorded via the paths (or the fields above) of this pathbuilder, are to be saved. Then click on "Save without form generation". Groups and paths can then be modeled.
