External standards this shape draws from or aligns with. See Shape design principles for how prior art informs shape design.
- ActivityStreams 2.0 — AS2’s Create/Update/Delete activities match our action values. We diverge by tracking changedKeys explicitly instead of encoding full object replacement.
- OpenTelemetry Traces — Closest fit for toolName/duration/success — span-shaped. Our activity is closer to a span event than a full span.
