 The file `polmat.ttl`contains a taxonomy of matters regulated by police ordinances. It is a SKOS vocabulary encoded in ttl/"turtle" format.
 
-The taxonomy has originated in the project "[Repertory of Policeyordnungen](https://www.rg.mpg.de/research-project/repertory-of-policeyordnungen)" of the [Max Planck Institute for European Legal History](https://www.rg.mpg.de/en). Initially this system of categories has been established in German in 1996 by Karl Härter and Michael Stolleis.
