HMML: HyperMedia Markup Language for composable, single-file web media
Summary
HMML (HyperMedia Markup Language) proposes a compact, composable imaging format that packs HTML/CSS/JS and media into a single binary .hmml file. It emphasizes editable, non-flattened content that models could emit directly, with a GitHub repo and a spec signaling an open-source approach to next-gen media formats.
