JSON Canvas

Announcing JSON Canvas: an open file format for infinite canvas data. Today we’re excited to announce that the Obsidian Canvas file format is now called JSON Canvas and has its own site, specification, and open source resources at https://jsoncanvas.org... we created the .canvas format with an open spec.

The goal of the Open Canvas Working Group (OCWG) is to establish interoperability between different infinite canvas tools. https://canvasprotocol.org

Discover a lowest-common denominator file format for storage and serialization.
Demonstrate real-time synchronization between different tools.

Q: Why not just push issues and pull requests to Obsidian's JSON Canvas? Why the separate organization, website, and name?
A: JSON Canvas is an excellent starting point, and if it already serves your needs we recommend it! OCWG provides a forum for larger discussions around canvas interoperability and additional resources for the development of those standards.
