Ailiance — KiCad 9+ Schematic Corpus (Copyleft)

🇫🇷 Ailiance — curated by Ailiance for production deployment ; co-published with the upstream electron-rare/kicad9plus-copyleft. 🇪🇺 Compatible EU AI Act (Template AI Office, July 2025).

Corpus de 209 schémas KiCad 9+ (.kicad_sch, format S-expression, version ≥ 20240722) collectés sous licences copyleft / réciproques fortes (GPL-3.0, CERN-OHL-S-2.0, EUPL-1.2). Compatible GPL-3.0-or-later au niveau aggregé. Pensé pour l'entraînement de modèles open-source soumis aux mêmes obligations de réciprocité.

Statistics

Métrique	Valeur
Total samples	209
Size	~2.1 MB JSONL (raw .kicad_sch ≈ 38 MB before chat-format wrapping)
Format	JSONL chat format (messages array, user/assistant)
Languages	French + English
Aggregate license	GPL-3.0-or-later

Composition

Copyleft / strong reciprocal licenses only: GPL-3.0 (169), CERN-OHL-S-2.0 (36), EUPL-1.2 (4).

Copyleft split of the original electron-rare/kicad9plus-sch-corpus (now deprecated). L'aggregé est re-licencié sous GPL-3.0-or-later, le plus restrictif des inputs (CERN-OHL-S-2.0 et EUPL-1.2 sont explicitement compatibles avec GPL-3.0+ via FSF / EUPL appendix interoperability).

General information

• Name: kicad9plus-sch-corpus (copyleft subset)
• Modality: text (KiCad S-expression source)
• Languages: English (technical), French (some title-block descriptions)
• Intended use: entraînement / fine-tuning de modèles de génération de schémas KiCad 9 / KiCad 10. Les modèles entraînés sur ce dataset doivent respecter les obligations GPL-3.0-or-later (disclosure des poids, des données dérivées d'entraînement, et du code d'inférence si redistribué).

Data sources

Publicly available datasets: None.

Web scraping: Yes — public GitHub repositories.

• Discovery method: gh search code "(kicad_sch (version 202X)" extension:kicad_sch
• Filtering: SPDX license detection of GPL-3.0, CERN-OHL-S-2.0, EUPL-1.2
• Per-sample provenance: see metadata.source_url, metadata.commit_sha, metadata.repo

Licensed data: None (no commercial / proprietary licenses).

Data processing

• Sparse-clone with gh repo clone --depth 1
• Per-file .meta.json sidecar with source_url, commit_sha, license_spdx, kicad_version
• Deduplication via SHA-256 of file contents
• Truncation at 8 KB to fit training context (marked in metadata when applicable)
• Validation via kicad-cli sch erc --format json --severity-all (99.6% pass rate on tested subset)
• All processing scripts available at https://github.com/ailiance/ailiance-bench/tree/main/scripts

Data characteristics

• Size: 209 samples, ~2.1 MB JSONL (raw .kicad_sch totals ~38 MB before chat-format wrapping)
• License mix (input):
  • GPL-3.0: 169 samples (80.9%)
  • CERN-OHL-S-2.0: 36 (17.2%)
  • EUPL-1.2: 4 (1.9%)
• KiCad version mix: 20240819 / 20240910 / 20241004 / 20241209 (KiCad 9 dev), 20250114 (KiCad 9 stable), 20250227 / 20250318 / 20250610 / 20250829 / 20250901 / 20250922 / 20251012 / 20251028 (later 9.x), 20260101 / 20260306 (KiCad 10)
• Source repos: 9 distinct upstream projects (full list in LICENSE_INVENTORY.md); largest contributors are jaguilar/kicad (133) and flaviens/kicad (34) — both KiCad demo / fork repositories under GPL-3.0.

Licenses applied

This dataset (the aggregated work) is released under GPL-3.0-or-later.

Per-sample original licenses are preserved in metadata.license_spdx and listed in LICENSE_INVENTORY.md. Downstream users MUST preserve attribution per sample and comply with the strongest applicable copyleft term (GPL-3.0-or-later for the aggregate).

Compatibility notes:

• CERN-OHL-S-2.0 -> GPL-3.0+: explicitly compatible (CERN-OHL-S §7 allows redistribution under GPL when combining with GPL works).
• EUPL-1.2 -> GPL-3.0+: compatible via the EUPL §5 / Appendix list (GPL-3.0 is a listed compatible licence).
• GPL-3.0 -> GPL-3.0+: trivially compatible.

Copyright considerations

• All sources are public GitHub repositories under copyleft licenses.
• The .kicad_sch files are treated as software source under their original licenses.
• Opt-out mechanism: contact c.saillant@gmail.com (Ailiance) to remove specific samples; nous respectons l'Article 4(3) de la directive DSM (TDM reservations).
• Reservations of rights: nous honorons robots.txt, les meta tags HTML noai / noimageai, et le protocole TDM Reservation Protocol (TDMRep) quand discoverable sur les repos sources.
