From @lauraclarke:

I think the citation widget gives people a way to meet cc-by attribution needs

They will need to be able to add attribution to whenever they reuse something, at the project level seems a good starting point, Ultimately we might want a way for someone to give us any identifier and getting an appropriate attribution text for that identifier in our system

A paper which might be useful in considering solutions https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0213090

And a blog post https://nlmdirector.nlm.nih.gov/2019/06/11/socio-legal-barriers-to-data-reuse/

Proposing the following text to be added the various places above:

@lauraclarke will how does the text below look? We would put this on the bottom of every download dialog (like the ones listed above).
