Presumption to publish criteria and notification form

Check our publishing criteria and let us know about your dataset.

Presumption to publish does not permit Public Sector organisations to publish copies of OS MasterMap, AddressBase or any other OS products, or extracts from them.

You've created your own dataset using OS data licensed to you under the Public Sector Geospatial Agreement (PSGA), which you would like to publish on data.gov.uk.

Prior to submitting your notification form, you need to be sure that your derived dataset meets our publishing criteria.

The best “rule of thumb” test we can offer is when you consider your dataset, do you just see an OS dataset with a few tweaks, or do you see a dataset that feels like yours? If your dataset is of the latter type, it is more likely to meet the presumption to publish criteria below but you will still need to check before submitting your notification. 

Check you meet our presumption to publish criteria

Meet our presumption to publish criteria? Great, tell us about your derived dataset

If you meet our presumption to publish criteria, you don’t need to ask us permission to release your dataset. When you're ready to publish your dataset – just simply let us know you're about to publish it on data.gov.uk by completing our presumption to publish form below.

If you are still unsure about whether you can go ahead and release your dataset after reading the criteria, get in touch and we can help you (choose government > PSGA on our contact form).

If you don’t meet our presumption to publish criteria but you still want to release your dataset, you can request an exemption.
