Consider code lists for jurisdictions

Rather than standardized strings such as ISO 3166-2 (e.g., DE-NW), it would – in RDF – make more sense to use codes. However, I am not aware of any standard dataset that has URIs for each such identifier, and it would be a lot of work to create our own. Wikidata has a property corresponding to ISO 3166-2 (https://www.wikidata.org/wiki/Property:P300), but this only solves half of the problem, because there is no straightforward way of saying "the range of ids:jurisdiction is anything that has a value on its wdt:P300 property".

After a brief discussion with @changqin26 @JohannesLipp @clange , we came to the conclusion to

• switch the range from xsd:string to xsd:anyUri
• extend the documentation to use the wikidata, e.g. https://www.wikidata.org/wiki/Property:P300
