Hypothes.is announced a partnership to bring annotation to epub e-books in 2017, but after 2018 no mention of it on their blog. Mailed them to ask about any progress since. Read someone's msg on Masto that they have trouble keeping epub annotations connected to the book (unlike e.g. my kindle annotations that reside in the book, but also are linked back to the location by my obsidian kindle plugin, maintaining the connection and reference. epub is xhtml so it should be doable.

epub is part of w3c standards (cause xhtml)

Apart from the framing of this post more as an apology than as a show of strength of keeping things simple and sturdy, interesting nuggets: Epub ebooks are xhtml and static so rapidly served without the need for a fancy framework or even a database. Flat texts are small, and their current collection fits in RAM entirely. PHP is used without frills. All in all a strong call to keep things simple, and to embrace my current use of php for local tools too: it's very fast.

Also makes me wonder: #openvraag what can one do with Epub books outside an ebook reader, in terms of excerpting e.g. and ripping things out for re-use elsewhere. I've got loads of them on my laptop
