The document discusses issues around data licensing compatibility. It notes that while open data licensing is becoming more common, license proliferation can cause problems. Specifically, it examines what license can be applied to improved or combined datasets when the original licenses are incompatible, such as those with "no derivatives" clauses. The document recommends using Creative Commons Attribution (CC BY) or public domain (CC0) licenses to ensure maximum compatibility.

- 4. State of Open Data Licensing ● Clear data licensing is (increasingly) common ● Choosing a licence is easy ● Plenty of guidance available ● Licence proliferation is becoming a problem – Vanity licences
- 6. When Is Compatibility Important? ● ● If I improve a dataset, then what licence can I apply to my new version? What happens when datasets are mixed together? – Can we comply with all the licences? – What licence can I use on the combined dataset?
