When you register a data set on data.overheid.nl, you are obliged to grant a license to the dataset. A license states how a dataset can be reused.
The table below lists the licenses that are used for data at data.overheid.nl. With each license it is indicated whether it concerns "open data". Some licenses impose restrictions on the reuse of the data.
Name of license
By granting this license, it is determined that it is not subject to known copyright restrictions, including all related and neighboring rights.
By granting this license to a dataset, the dataset is assigned to the public domain by relinquishing the rights to the copyrighted work worldwide, including all associated and related rights, to the extent permitted by law.
Geo Shared license
In some cases it is necessary to set conditions of use, for example by legislation. In such cases, the Geo Shared license offers a solution.
With this license, a (re-)user is free to share, copy, distribute and transmit the dataset via any medium or file format. The dataset may be edited and used for commercial purposes. Reference to the source of the data is required.
With this license, a re-user is free to share, copy, distribute and transmit the dataset via any medium or file format. The data may be edited. Reference to the source of the data is required. In addition, it is a requirement that derivative products are made available under the same conditions (as open data).
License with limitation
Licenses for reusing data
When in doubt, we always advise to choose the CC-0 license. CC-0 clearly indicates to re-users that the data can be used without restriction. More information about licenses can be found on the Creative Commons website, about licenses.
If it is unclear what the license is for data that will be made available, you can temporarily opt for an "unknown" or "not open" license. The data sets are then not regarded as open data, because it is (still) unclear whether there are limitations in reuse.
If an administrator uses "unknown license", the supplier indicates that he/she does not know which license applies to the dataset.
No reuse license
No open license
If a supplier uses "no open license", it means that the data set is not public and must be requested from the relevant government organisation
