# Go API Framework ## Overview This document describes the API source tree represented by the project-root placeholder `source`. The structure separates shared data resources, framework-owned foundations, software-specific extensions, runtime composition, and project-level files. ## Architecture ### Data The `data` directory provides the common resource system for framework-owned and software-owned embedded data, using a central cabinet, data-specific ledgers, and resource handlers to register and resolve resources through a controlled and lightweight access path. -
