Hi all,
The municipal archive of Rotterdam (Stadsarchief Rotterdam) has recently made a number of databases available under CC0, which might be of interest to the Wikidata community. These include birth, death and marriage data for the period 1811-early to mid 20th century, as well as cadastral data for 1832 and a street name database. They can be accessed here http://www.stadsarchief.rotterdam.nl/vraagbaak/open-data (in Dutch only). If anyone decides to reuse these data, please share it here as well so that the archive can also be informed on any use.
Best,
Arne Wossink
