SBOM Bridging Ontology for Mapping

Namespace: https://w3id.org/sbom/

A SKOS vocabulary of stable, persistent identifiers for the minimum elements (baseline attributes) required in a Software Bill of Materials (SBOM), together with SSSOM crosswalk files mapping those elements to exchange formats.

Concepts from the SBOM ontology are used in the see_also column of SSSOM mappings to provide additional mapping justification.
