Recovering my work due to possible future events

So far, Obsidian looks like a great way for me to take and organize notes, and I’m deciding whether or not to invest my time into learning and using it. My concern is loosing my notes due to some event years from now (new version, reorganization, …).

My notes will mostly record research results and learning. And, I think I might be able to make Obsidian functionally similar to a mind map.

The features I’m most concerned about are math ($$) and canvases.

I am a markdown beginner. Long ago I worked with TeX. And for years I’ve used Mathematica.

I’ve learned some on my own

For math, I’ve found that Joplin might work with Obsidian markdown, and at worst I can mine Obsidian markdown to extract TeX expressions.

For canvases, I’ve found that the underlying image (a jpg file for example) source is recorded in plain text. So I can mine Obsidian markdown to extract source names. I’m OK with loosing cool things like arrows.

I’d like to get other’s thoughts

While I’m fairly sure I can at worst recover source information for potential use in some interactive application/reader (browser, editor, or something I write), I’d love to know if there’s already another application (non subscription) that can do a ‘pretty good’ job of working interactively with Obsidian markdown. Possibly using some sort of conversion script.

Are my thoughts regarding worst case extraction flawed? I’m speaking about core Obsidian markdown, not plugins.

To repeat, I like what I’ve seen of Obsidian. And, I’m looking forward to using it.

If you have electricity, and a working device (PC, whatever) with a working OS (operating system), you are ensured to use the app/program forever. Just keep a few copies of installers here and there.
I’d say stock up on Obsidian matches and candles too but I don’t know where to download those. :slight_smile:

The files are yours forever. You are not forced to keep anything online. Keep copies of those too and in case you need to modify any syntax (maths, links, image references, etc.), you can use regular expressions.

Sometimes the best ideas are the simplest. Keeping old versions around is a great idea; it’s going on my todo list.

I don’t know where to get to get Obsidian matches either. Bummer. :wink:

I’m still interested to know if If there’s a case where Obsidian hides image references within binary structures. So far, everything seems to be in plain text.

Thanks gino_m!

And I had some situations where I needed to keep old PC hardware around to run ancient Microsoft OS versions and applications. I had forgotten till reading your suggestion.

To be honest, I downloaded and filed away some installers just reading your post myself.
I started doing that when we only had internet at the town library. I think I still have some old Winamp installers…
