Yeah, that’s the only page I’ve found each time I’ve looked - and they do put up an SEP field around NC, but don’t say what they don’t like about SA …
I agree ND isn’t very suitable for this sort of use - it’s more appropriate for “Finished” works of art - though even then I think it says more about the copyright holder than the Value of the work - so aside from perhaps ‘protecting’ some extremely artistic image that someone is precious about, it effectively means you’re saying I can’t even comment on or add an ID to your observation, because that would create a derivative work. Not terribly useful for a community refined data set.
[ I’m similarly a bit surprised inat even allows people to select “all rights reserved” - because that means even inat doesn’t have any right to redistribute or let users make additions, except if you argue that the inat ToS somehow has precedence over the user’s explicitly chosen licence …]
But SA doesn’t limit what you can aggregate with it or what licences those things can be under - it even doesn’t prohibit you from saying “my original contributions have licence X” in a derived work, as long as people who receive it are also free to redistribute it under the same terms as the original creator did. That’s why it’s ok for inat to include work under all the licences it does, and why it’s ok for ALA to import all of that work (and it rides the fence of being the Australian node for both inat and GBIF :) All of those datasets include machine readable licences now, so any user that might be a problem for can filter for licences they like themselves anyway.
That’s why I’m curious what GBIF’s actual rationale is … all I can think of that might sort of make sense is that the lawyers for the kind of publishers who traditionally required researchers to assign their copyright to the publisher before their paper would be included in an expensive subscription-only journal thought they might be able to argue that was “non-commerical” because they never pay the people who did the work to produce the paper - but worried that SA would give people (including the original authors) a clear right to continue to publicly share the paper after that assignment …
I don’t know enough about GBIF though to know why they might care about that, so I kind of hoped someone who does might see this thread :)
Without a good reason to think otherwise I’m still inclined to think and tell people that if GBIF doesn’t like SA licenced work from “community” contributors, then that’s their problem not ours …
