Properties

createdAt string datetime Required

An RFC 3339 formatted timestamp.

scene blob Required

Gzipped Excalidraw scene JSON (serializeAsJSON output, gzip level 6), as captured at checkpoint time.

maxSize: 50.0 MB

subject ref com.atproto.repo.strongRef Required

Strong reference (uri + record cid) to the parent app.lexidraw.scene record at checkpoint time.

thumb blob Optional

WebP preview of the scene (max 1024px on the longest side).

maxSize: 2.0 MB
