The document discusses the concept of a Next Generation Digital Learning Environment (NGDLE), which envisions moving beyond traditional learning management systems (LMS) to a more distributed learning ecosystem. Key points include: - An NGDLE would allow tools both inside and outside the LMS to be integrated through standards like LTI and would break down "iframe-d walls" that silo content and tools. - Interoperability across systems is a challenge as different tools and LMS still exist, so user experience and authoring tools need to be unified. - The "headless authoring experience" or HAX seeks to provide a common authoring experience for instructors and instructional designers across different tools and systems
