Another source to extract is Dienst Wegverkeer (RDW) https://opendata.rdw.nl/

Geodata is mainly in data sets under https://opendata.rdw.nl/browse?category=Parkeren Please note to skip any derived data sets. For some sets, area ID needs to get looked up in another collection for coordinates. (Not clear where, needs to be investigated further.)

Also some collections contain address information, e.g. https://opendata.rdw.nl/Erkende-bedrijven/Open-Data-RDW-Erkende-Bedrijven/5k74-3jha An API account needs to be created in order to access to more functionality such as some maps, but is not needed to gain access to the data which all has license CC-0 as it is open government data.

There are a lot of data sets, but many are derived sets which can be omitted. These are identified by GEMEENSCHAP, Data Lens or Gebaseerd op.

Sander, thanks for suggesting this dataset. Can you elaborate further why any these datasets should be included in NLExtract? And which datasets actually? Does any of them contain complex GML requiring additional processing.

For comparison, we decided against including Bestuurlijke Grenzen in NLExtract, since this is a simple GML format which can easily be read by plain ogr2ogr. Generally, the basisregistraties, like TOP10NL, BRK, BGT and BAG, have a very complex structure, which can't be processed by standard tools without losing a certain amount of information.

The rational is e.g. for the development of OSM-based parking apps. I got the impression last week at the hackathon that NLExtract would like to be a one-stop-shop with the benefit that if a government body stops making a data set available, it is still available here. But if this now doesn't meet the criteria at this time, we can close this and the API they offer suffices.
