Selfhosted

I am looking for a tool/workflow, with which I can manage a collection of all the stuff I see on the internet and elsewhere, that they are worth reading at a time in one place.

This includes:

• blog articles I randomly find on the internet
• social media posts
• news articles from RSS feeds
• books (pdf,epub,...)
• wikipedia articles
• topics I want to do further research on
• aso...

A lot of these things are bookmarks, I know that. I tried to manage my "ToBeRead" list in bookmarks before, but it didnt work out for me, because some things simply aren't URLs, that can be bookmarked (e.g. PDFs, just names of research topics).

Besides that, longer threads on mastodon/lemmy e.g. can be easily bookmarked in the app itself, but than you start to manage multiple lists in multiple locations, which I want to avoid.

I am running my own Nextcloud instance and would like to also sync this stuff across devices with it.

I figured out (while using obsidian) that my brain works better when I dont have to worry about where to put things, but just tag them with topics, by relevance, e.g. So tags and the option to filter them would be nice!

Thanks beforehand :)

Edit: Doimg this with Nextcloud Deck, or synching an Obsidian Vault with Nextcloud came up to my mind, but I couldn't come up with an idea for a conveniant workflow, but maybe it's easier than I think?
