Yeah, I just stumbled upon this project and wanted to share, I'm currently using Obsidian for my personal wiki, but I use Zotero a lot as a paper repo and reader, the organization and metadata tools are great, and extending it to a more powerful note-taking tool seems like a no-brainer.

Now it just needs an EPUB reader to replace Calibre, then it'd just be the perfect all-in-one personal library. For now I'm using this plugin that exports and keeps in sync the calibre library to Zotero:

Very grateful that this open source project stays alive, I've seen attempts over the years from startups and other projects to tackle on spaces like pkm, research, paperless office, to then be abandoned yet Zotero keeps getting updates.

There's also Tropy, from the same organization that develops Zotero, for organizing digital assets:

Getting a bit off-topic, but this thing could use some sort of Moodboard designer to visually sort the assets in a canvas, kind of what you can do with Miro, Notion, Mural or locally with Obsidian Canvas/Excalidraw. On that note, there's also this project that takes on that space, previously featured on HN but has made significant progress lately:
