HMML: A Conceptual Framework for Composable Document Generation Over Static Pixels

This article introduces HMML (HyperMedia Markup Language), a conceptual framework that proposes generating composable documents instead of static pixel-based images. The core idea is that AI models should output structured, editable elements (vector, text, raster, 3D, motion) at the node level rather than flattening everything into a frozen raster grid. The article argues that "image" is an overloaded term and HMML offers a way to un-conflate it, though it remains speculative about whether models will adopt this approach.
