Open datasets

The city archive makes as much information as possible available from our databases. This makes the exchange of information easier and promotes re-use. You can find datasets via the “open data portal” and “Rotterdam open data store”.

Open datasets

The open data portal contains so-called "NTI"s or "Nadere Toegang per Inventarisnummer" (Further Access by Inventory Number). The choice was made to collectively describe all NTIs that refer to a similar source and have a similar structure. The context of the sets includes:

  • Contents of the dataset
  • Context of creation
  • Maintenance, changes and additions
  • Reference to source data with explanation of the source
  • Standard used
  • Format
  • Licence
