Meeting 3 Summary:
The shared goal for the group is to design a least-common denominator extensible format that sits between visual and structural canvases, allowing them to interoperate.

1. "JSON Canvas 2.0": The primary focus is developing a new spec, which we casually refer to as JSON Canvas 2.0, inspired by Obsidian's format. The goal is to create a minimal, file-based format that can be extended to support a broad range of canvas types​​.
2. Handling Diverse Feature Sets: Discussion on how to manage diverse features across different canvases. Ideas include defining fallback content types and MIME types for objects to ensure compatibility​​.
3. Schema and Extensibility: The group discussed the need for items and relations to have schemas and how these schemas should be distributed. The idea of leveraging existing formats like SVG for shapes was considered​​.

Action Items

1. Discuss and decide on specific changes and extensions for JSON Canvas 2.0​​.
2. Work on a minimal interop between Excalidraw and TL Draw. Volunteers needed for similar interoperability efforts with other tools​​.
3. Explore ways to define and handle fallback content for complex objects to ensure minimal data loss when transitioning between different canvas tools​​.
4. Draft a minimal spec for JSON Canvas 2.0, including schema definitions for items and relations​​.
