A collection of common questions and answers regarding the bulk data exports released by OpenSanctions, and the file formats that are offered.
Most data sources are updated every four to twelve hours. Refreshed data exports are published several times a day (currently ca. every five hours). You can see a list of any errors or warnings each dataset has generated.
For data sources that require screen scraping rather than publishing structured data, a HTTP response cache with a maximum age of 14 days is used to avoid running into rate limiting errors.
We publish the source code for the data processing stack used to build the OpenSanctions data. This means that anyone can build their own versions of the data. However, a lot of the value added to OpenSanctions comes from how we use these tools, rather than the tools themselves. For example:
opensanctions.org using the data.
sy_obsalytics) use non-open data to be built, and you will need to contact their publishers before including the data in your distribution, or exclude these sources.
When you're building your own version of the data instead of contributing to the project via a data license, please act as an open source contributor instead of a customer. Don't request real-time support via Slack. Contribute your own GitHub issues and patches if you notice any issues with the code base, and contribute documentation if you notice holes in it.
