Tried installing be93233 on my Kobo Libra 2 with KoReader 2023.01. After copying over my full Zotero directory and setting the Zotero path in KoReader (worked fine) the plugin crashes at

main.lua:366 attempt to call method 'init' (a nil value)

Zotero's Web API v3 allows syncing annotations, which in Zotero will include annotations for PDF, EPUB, and HTML (which is a pretty large subset of what KOReader allows for annotation too). Zotero's annotation offerings uses the open Web Annotation Data Model schema are actually quite similar to KOReader's - there is a start and stop position for a highlight, a copy of the highlighted text 'style' (colors for Zotero, vs. highlighted/underlined/strikethrough/invert for KOReader), and a few more fields. Both of them also support basic text notes which are both anchored to highlights.

I think there is sufficient feature overlap that there could be a translation layer that displays Zotero annotations as KOReader annotations when the Zotero attachment is opened in KOReader (after browsing and selecting). Eventually even modifying/adding/deleting annotations in KOReader and syncing the changes back to the Web API would be ideal, but read-only would be a first step. This would make annotations much more valuable as they are no longer isolated to one system. (Ideally, a universal file format based on WADM might be better, but two largely supported programs is better than one).

There are some issues to overcome with annotation translation:

1. KOReader highlights are positioned differently from Zotero's (e.g. different coordinate 0,0 orientation, different scale, more). I tried to figure this out a few months ago but didn't get there
2. KOReader highlight styles are primarily intended for black-and-white screens while Zotero highlights are only stylized by color (and RGB color is allowed, but the UI picker only shows ~9 options). My initial idea has been to map the first four preset Zotero colors to the four KOReader black-white-friendly options, but KOReader color highlighting may be added soon and partially solve this.
3. KOReader's bookmark and highlight structure in Lua docsettings are a bit confusing.
4. Zotero area selections and hovering notes (not anchored to text) don't have a corollary in KOReader (maybe add them as a KOReader FR in the future?). Technically neither do Zotero item notes (not attachment notes), but the latter one can probably be ignored. Zotero will probably add more features, and only some will be KOReader-recognizable.
5. Would need to decide how to deal with offline Zotero annotation storage in KOReader, though I think the plugin itself needs to be further developed first.

Here's an example set of highlights in Zotero on top, the same in KOReader on bottom, followed by the data structure used for the two Zotero highlights which I think is accessible via Web API:

I might be able to help build this at some point, but I don't currently have the time. I have the beginnings of a translation layer in Python but it's early on and needs to be in Lua anyway.

Hi! Thank you very much for the Zotero plugin on KOReader!
It is great! Works reliably.

Can you please make an option to enter selection mode (and also a button to select all), select multiple articles, and them put them in the queue for download?

Ideal case is when I create a new collection, say This evening, put 10-12 articles and then go into KOReader and download them all to read.

Thank you!

Hi! Thank you very much for the Zotero plugin!

Can you please make the number of items per page configurable?
Or at least the same as in FM - Info items per page (top menu setting).

The problem is that now I have 14 items on Kindle Scribe's 10 inch screen. When I have 40-50 articles, it takes me long time to skim through multiple pages.
I used to have 20-30 items per page in FM and info lists.

Thanks!

I followed the install instructions, added the user id and api key, Synchronize shows the 'success' message, but browse doesn't show any item, only "No items" at the bottom.

Any ideas?

I have several entries (links and pdfs) in the zotero library. If relevant, I only use the web interface (never installed the app).

I sync my whole library to other devices and read the files locally.

Would be nice if you could keep the local browsing option as the plugin improves.

Hi @stelzch

Recently, we fixed an issue in the plugin that was not marking newly downloaded articles as Reading.
This resulted into newly downloaded and opened not being shown in the History - Reading section.
It required to exit the book - by going to FM, switching to another book, or closing the KOReader - to be able to mark it.
This prevented me from quickly skimming through multiple articles back-and-forth.

The problem is solved in this line:

                ReaderUI:showReader(BaseUtil.realpath(full_path))

See linked comment with the fix and associated ticket in KOReader's GitHub.

Thank you!

Hi,

Thanks for this great app!

I prefer to manage all my documents - even ebooks - in Zotero. Therefore, I wish we could handle and read even epubs and not only pdfs via this plugin.

All the best!

Hi! Thank you very much for the Zotero plugin.

Dispatcher action for Zotero doesn't work - I assigned it to a gesture, but it does nothing when I trigger it. The same story when I put it in Quick Menu.

Thanks!

Hi!
I can see Zotero tries to open settings upon init:

Thanks!
