SCALE — Shared Concepts, Attributes, and Links with Evidence (scale-catal)
Copyright 2026 SCALE contributors

Licences
  Each file's licence is given by its path in REUSE.toml; the licence texts are in LICENSES/.
  - Code (Python, tools/, packaging and CI files): MIT (LICENSE, LICENSES/MIT.txt).
  - Vocabulary (the science kernel and the catalysis domain), curated records, examples, documentation,
    governance, the skills' texts, the texts of the domain-template test fixture
    (tools/tests/fixtures/domain-template/) and the releases (releases/v*): CC-BY-4.0
    (LICENSES/CC-BY-4.0.txt). Attribute them to "SCALE contributors" with a link to the repository
    (CITATION.cff says how to cite).
  See governance/licensing.md.

Third-party material
  Material not created by the SCALE contributors stays under its owners' terms. The repository holds no
  third-party text under copyright: it cites names and identifiers only, and quotes within a copyright cap.

  Public-domain works: examples/methanol-synthesis-public/pdfs/ and texts/ hold copies of 55 sources that are
  public domain in the United States (works first published before 1931, US patents, a Polish patent as an
  official document), with each source's basis in that folder's rights.yaml. Outside the United States some may
  remain in copyright (LICENSES/LicenseRef-PublicDomain-US.txt).

  Names of external vocabularies and standards (OWL-Time, the Evidence & Conclusion Ontology, Gene
  Ontology causal activity models, OPTIMADE, SSSOM and others) and identifiers of their terms are cited;
  no text of them is reproduced. The exporter for the knowledge-graph bundle format (kg-bundle,
  tools/kgbundle.py) is SCALE code; no code or text of the format's specification is included.

Project data
  Curated project data that is not cleared for publication is never committed: every committed document
  states access public, and `scale check` verifies it. Such data stays with its project, under the
  project's own terms; neither licence above applies to it. See governance/licensing.md.
