SBOM Bridging Ontology for Mapping

A SKOS vocabulary with stable, persistent identifiers for SBOM minimum elements, plus SSSOM crosswalk files mapping those elements to SPDX and other exchange formats.

SBOM Bridging Ontology for Mapping is a SKOS vocabulary that provides stable, persistent identifiers for the minimum elements (baseline attributes) required in a Software Bill of Materials (SBOM), paired with SSSOM crosswalk files that map those elements to exchange formats.

The vocabulary bridges different SBOM specifications — including the NTIA SBOM minimum elements and G7 AI SBOM — and maps them to SPDX 3.x.
