Obsidian JSON Canvas

JSON Canvas is an open-source file format designed for infinite canvas data, functioning as a digital whiteboard for organizing information spatially. It was originally developed to provide a standardized, human-readable data structure that ensures interoperability between various digital tools and apps that utilize infinite canvas interfaces.

Created by the team behind Obsidian, the format is released under the MIT license, making it free for any developer to implement as an import, export, or storage format. Because it is a digital specification, it is not manufactured in a physical sense but is maintained and expanded by a global community of developers and open-source contributors.
