Current version on website (LauNuts2021b.nt.zip) yields "invalid IRI value" when importing into GraphDB

[simon-gross]

Importing the current version (LauNuts2021b.nt) into GraphDB yields the following error

org.eclipse.rdf4j.sail.SailException: Invalid IRI value

The reason seems to be a "|" character in line 729297 for IRI <https://en.wikipedia.org/wiki/Belgium|state>

Removing the character fixes the error.
