Copyright information captured for texts in books

We need to capture copyright metadata for different languages for the text in books.

When we want to publish a multilingual book and we want to use text someone else translated we need to know who to attribute to. (minimum requirement)
We can then do this attribution by hand for now but need to find who

It would be nice if it worked like pictures where all the texts in the published output would be collated into the copyright statement

Bloom already tracks the original copyright (who owns the original text) and the copyright on the current translation. But I suppose if the book is being published as a triglot, or a diglot where the second language is not the original, we could need to display another copyright.
