A few points (any thoughts on the below @canwaf, more your bag than mine, happy to take a steer).

The PURL link for the european licence seems to be down and/or broken so I've switched to an alt source.

I've also included the 1.2 version of the European Licence (no idea if that's a good idea).

Updated csvcubed documentation is in this pr: ONSdigital/csvcubed#486 , have not listed the older CC licenses as there's a strong recommendation to use version 4.0 (the older ones do not cover data in databases, or something along those lines).

@robons - have added the other creative commons licences.

There was a comment on the task about adding an all rights reserved licence but I'll need some guidance if you want that, I couldn't find anything that seemed appropriate.

Perhaps this, whilst not technically a license, makes it clear that no one else has permission to use the data at all for any purpose and that a user deliberately avoided selecting a license (rather than just forgetting).

What do you think about adding that in?

[robons]

Looks good, just make sure to update licenses.json with these new additions if you could.

We collected a bunch of open license URIs at https://bbcarchdev.github.io/inside-acropolis/#licenses a few years ago.

thanks both, incorporated the additional licences before merging
