What is PRISM?
PRISM (Privacy-Respecting Instructional Schema & Markup) is an open JSON format for educational content. It packages lessons, assessments, and multimedia into a single portable file that works anywhere.
Unlike proprietary platforms, PRISM files are plain JSON — readable, editable, and shareable without vendor lock-in. Every PRISM resource carries its own privacy declaration, ensuring transparent data handling.
