There was a very nice spanish community that would scan/ocr books and convert them into epubs. They had very high standards and their forums were full with epub documentation, best practices, boilerplate/skeleton files, scripts, etc. To the point their curated epubs were better than those of some publishers.

It all died when one of the founders was arrested.

Edit: it seems my information was incorrect, the site's owner sold it and the new owners wrapped the download links with malware and closed the forum. Users left and the site closed.

Sounds awesome. Any links to remaining documentation?

I just googled and it seems like the users have moved over to https://www.epublibre.org/foro/

On the front page it shows a warning about how applications for editor are closed due to having too many. So it seems the community is still alive and well. Here's their documentation as an epub (in Spanish): https://www.epublibre.org/libro/detalle/2398
