0.7.0

As it stood at this release: the repository · the docs · the knowledge bundle · the release

Added

  • The documentation site’s home page has a Schema button, which opens the schema’s pages.
  • The build checks that .lokf/slsa.yaml matches the schema and .lokf/lokf.yaml.
  • The README says what the schema models, what shaped it and what it maps to.

Changed

  • The knowledge bundle needs lokf 0.9.0, and .lokf/slsa.yaml, the release’s schema asset, is regenerated by its released adapt. The slot revision is slsa_revision in the copy, with its IRI unchanged, because LOKF 0.9.0 defines revision; a host concept that writes revision for an SLSA source revision renames the key.

0.8.0 Latest

As it stood at this release: the repository · the docs · the knowledge bundle · the release

Changed

  • The in-toto layer comes from lmodel/in-toto’s core module at v0.1.0, vendored at src/slsa/schema/in_toto/in_toto_core.yaml, and the schema’s own copy is gone. The class names stay, and the six classes and their keys take in-toto’s IRIs; media_type and algorithm take the IRIs LOKF gives them.
  • SlsaPredicate extends in-toto’s InTotoPredicate. A statement keeps its predicate key, which the adapt copy calls slsa_predicate, because LOKF’s predicate is a relation’s type.
  • attestation_storage_uri, signing_tool and transparency_log_entry moved to SlsaStatement, a subclass of InTotoStatement that SlsaDocument holds, since in-toto’s statement carries only what its specification defines.
  • build_type, builder_id and verifier_id take in-toto’s in_toto_type_uri, and started_on, finished_on and time_verified take in_toto_timestamp, the field types the SLSA specification gives them. A timestamp now ends in Z, and a type URI keeps its scheme and host in lowercase.
