# Component licenses

This is an aggregation with distinct component terms, not a blanket relicensing
of upstream content. The card's `other` license points here.

- **PlotQA-derived images, questions, tables and evidence:** Creative Commons
  Attribution 4.0 International. The official PlotQA README explicitly applies
  CC BY 4.0 to its datasets; its MIT license applies to code/models. Preserve
  the PlotQA attribution and the description of our re-rendering and edits.
- **CLEVR-derived images, questions, scenes, programs and evidence:** Creative
  Commons Attribution 4.0 International, as stated on the official CLEVR page.
  Preserve the CLEVR attribution and identify these as modified/re-rendered
  evaluation views. CLEVR generator code/assets have their own BSD license;
  the upstream generator/assets are obtained separately, not bundled here.
- **Release-authored labels, edit recipes, documentation, benchmark metadata
  and scoring projections:** CC BY 4.0, to the extent the project holds rights.
  This does not grant additional rights over source datasets or model weights.
- **Project software under `src/` and `scripts/`:** Apache License 2.0,
  following the existing project's `pyproject.toml` declaration. Upstream
  attribution must remain intact. External dependencies retain their licenses
  and are installed separately; their binaries and model weights are absent.
- **GQA upstream questions, full programs, scene graphs and photographs:**
  not redistributed. The official GQA site and downloaded archive READMEs
  checked on 2026-09-28 do not state an explicit annotation redistribution
  license. A local configuration's `cc-by-4.0` declaration and third-party
  mirror cards are insufficient evidence to settle that grant. Users obtain
  these inputs directly from the upstream source under its applicable terms.
  The GQA index contains our labels, factual source IDs and our edit deltas.
- **Manuscripts:** not bundled. Their publication/license selection is separate
  from this dataset preparation.

Full license texts are in `licenses/CC-BY-4.0.txt` and
`licenses/Apache-2.0.txt`. The upstream PlotQA MIT and CLEVR BSD notices are
also retained for clarity; they do not replace the dataset CC BY terms.

CC BY users must credit the creators, link the license, identify modifications,
retain applicable notices, and not imply upstream endorsement. No extra legal
or technical restriction is placed on the rights granted by that license.
The official Visual Genome site links CC BY 4.0, but this does not resolve the
separate GQA annotation grant. Original image-owner and other third-party rights
are not overridden. See `ATTRIBUTION.md` for the source links and modifications.
