Evidence claims:
- [sourced_fact] Spec site: still a work in progress, contains a subset of features approved by the Lottie Animation Community; defines a JSON format whose top-level object is an Animation, with sections on values, properties, composition, layers, shapes, assets and a JSON Schema. · locator: Spec front page · source: https://lottie.github.io/lottie-spec/latest
- [sourced_fact] License.md: specifications are subject to the Community Specification License 1.0; code included in the spec is MIT, and the spec license prevails in conflicts. · locator: License.md, Specification License section · source: https://github.com/lottie/lottie-spec/blob/main/License.md
- [sourced_fact] README scope: the working group specifies the allowed JSON structure, semantics and how Lottie files are rendered, using written verbiage plus exemplar files and renderings. · locator: README scope paragraph · source: https://github.com/lottie/lottie-spec
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
