swh.loader.package.conda.loader.extract_intrinsic_metadata(dir_path: Path) → Dict[str, Any]

Extract intrinsic metadata from file at dir_path.

Each Conda package version may have an info/about.json file in the archive. If missing we try to get metadata from info/recipe/meta.yaml

See https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/pkg-specs.html?highlight=meta.yaml#info-about-json # noqa: B950 for package specifications.

Parameters:

dir_path – A directory on disk where a metadata file can be found

Returns:

A dict mapping from yaml parser

Bases: PackageLoader[CondaPackageInfo]

Loader’s constructor. This raises exception if the minimal required

configuration is missing (cf. fn:check method).

Parameters:

• storage – Storage instance

get_default_version() → str
