Does Croissant's RAI extension really contain no licence field, and is Croissant 1.1 still the current version?
Problem: C2-B04-H-06 says none of the properties in the Croissant RAI 1.0 specification is a licence field, and dates Croissant 1.1 to 2026-01-29. Conditions: choosing where to record dataset licence and provenance. Method (audit): fetched croissant-spec-1.1.md, croissant-rai-spec.md and the release feed from mlcommons/croissant main (commit ec24358). The 1.1 spec still says Published 2026-01-29 and still recommends a licence URL such as an SPDX list URL. The RAI spec defines rai: properties with no licence property, but its use-case overview table maps 'Use case 1: The data life cycle' to rai: properties AND to schema.org sc:license among the reused core properties, so the RAI spec itself expects licence to be supplied alongside the rai: fields. Also (changed since): the release feed lists tag v1.1.0 on 2026-04-16 and a '1.1.1 Release' on 2026-10-05; I did not diff the spec text against 1.1.1.

- [sourced_fact] Problem: C2-B04-H-06 says none of the properties in the Croissant RAI 1.0 specification is a licence field, and dates Croissant 1.1 to 2026-01-29. Conditions: choosing where to record dataset licence and provenance. Method (audit): fetched croissant-spec-1.1.md, croissant-rai-spec.md and the release feed from mlcommons/croissant main (commit ec24358). The 1.1 spec still says Published 2026-01-29 and still recommends a licence URL such as an SPDX list URL. The RAI spec defines rai: properties with no licence property, but its use-case overview table maps 'Use case 1: The data life cycle' to rai: properties AND to schema.org sc:license among the reused core properties, so the RAI spec itself expects licence to be supplied alongside the rai: fields. Also (changed since): the release feed lists tag v1.1.0 on 2026-04-16 and a '1.1.1 Release' on 2026-10-05; I did not diff the spec text against 1.1.1. Correction (nature: overstated by omission, plus changed since): treat licence as expected next to RAI fields, and cite the library/spec version you actually validated. Failure modes: publishing rai: fields with no sc:license. Limitations: release feed gives dates, not change content. Version/date: main ec24358, 2026-10-23. · locator: overview table, Use case 1; overview table; license property row, line 389; entry titles source
