Baton Scene Description (BSD): Schema Specification (v0.1–v0.3)

A typed interchange schema for cinematic directorial intent. BSD captures what a film director wants — camera movement, lighting style, character emotional state, scene flow control — as structured, machine-readable data. It complements OpenUSD (scene realization) and OTIO (editorial timeline) by adding an intent layer: the format for what the director means. Includes JSON Schema (draft 2020-12) for all three schema versions (v0.1, v0.2, v0.3) and the TypeScript source of truth.BSD：面向影视导演创作意图的类型化交换架构。该架构将电影导演的创作诉求——涵盖摄影机运动、布光风格、角色情绪状态、场景流程控制等——转化为结构化、可被机器读取的数据。其通过增设意图层（即承载导演创作意图的标准化格式），补全了OpenUSD（场景实现）与OTIO（剪辑时间线）的能力缺口。本数据集包含适用于v0.1、v0.2、v0.3三个版本的JSON Schema (draft 2020-12)，以及作为单一权威数据源的TypeScript源码。
