Small update from my side. After downloading the latest ttl file from Wikidata I receive no errors but also no output. I tried the exact command with a small dataset and that worked.

As I was having some issues with compiling the code I used a docker instance directly for the conversion unfortunately it failed due to rdf syntax reasons while using the latest database. As I didn't time it I cannot give any details yet about the performance.

The issue identified was because the custom-config.json was not overwriting the settings stored in default-config.json. To overcome this a pull request was made that overwrites the default-config.json file upon startup.

So if I understand it correctly, Q33512910 is the historical entity of Wageningen and Q1305 is the current city of Wageningen? What exactly is meant by historical? 100 years, 10 years? ... Also can we not report in the current wageningen historical changes using e.g. the end time property? In the "old" city it should then be clearly mentioned that this is an old city with a rough end estimation or not?
