This package's output follows the Cross-Domain Interoperability Framework (CDIF) profiles published by CODATA
(https://cross-domain-interoperability-framework.github.io/cdifbook/) and the CDIF metadata building blocks
(https://github.com/Cross-Domain-Interoperability-Framework/metadataBuildingBlocks), used as Creative Commons
Attribution 4.0 sources. The tests validate against the CDIF validation repository
(https://github.com/Cross-Domain-Interoperability-Framework/validation, CC0) at a pinned commit. The pinned validation artifacts
are copied into data/ under their own licences, named by commit, so a passing document says which CDIF it passed.

The sixteen exceptional values in src/sdccdif/data/sdc4-exceptional-values.json are extracted from the SDC4 reference
model schema (https://semanticdatacharter.com/ns/sdc4/sdc4.xsd), Semantic Data Charter.
The model's package is read with sdcreader (https://github.com/SemanticDataCharter/sdcreader), Apache-2.0.
