JSON Canvas Spec
- bryanrasmussen - 6914 sekunder sedanIt would be useful to have examples of data and the representation this would result in.
Although you can go to https://jsoncanvas.org/ itself and see an example rendering, you cannot see the exact data that created it - I think, although you can sort of guess since the element names are stuff like node.
I sort of doubt this is the best data structure for representing this kind of thing. Maybe I'm wrong though but I would think I would go for something like https://github.com/jsongraph/json-graph-specification which strikes me as closer to graphml which I have some experience with, and maybe give it ability to embed videos etc. (which for all I know someone already has)
This is all an initial feeling though, like hmm, no I think it's wrong, and maybe I am just not seeing why this would be better than another solution.
- kepano - 1260 sekunder sedanI'm not sure why it popped up today, but it's nice to see it on HN again! A brief timeline with some links to past discussions:
- 2022: The .canvas open format was created for Obsidian Canvas [0].
- 2024: Official 1.0 spec of JSON Canvas [1].
- 2024-2025: A number of apps/libraries built up around conversion, storage, and import/export [2].
- 2026: Obsidian Skills [3] includes support for .canvas (along with .md and .base) to make it easy for LLMs to read/write JSON Canvas, and opens interesting visualization/interaction patterns with agents.

- obsidianbases1 - 2545 sekunder sedanI've used canvas quite a bit since it was release in Obsidian. It's good, not great, but the simplicity of the file type opens up a lot of opportunities to build on top of it.
- Garlef - 3230 sekunder sedanI'm not sure about this:
An "infinite" canvas without some notion of recursion such as viewports feels incomplete.
- makeitrain - 7306 sekunder sedanLooks cool. I recently hit some limits with mermaid and this seems a little more flexible.
- MoonWalk - 5810 sekunder sedanAre pixels really the best way to encode position at this point?
