CycloneDX vs SPDX for CRA readiness workflows

How supported SBOM formats can feed intake, normalization, vulnerability review, and retained evidence.

For SBOM and platform owners

Both formats can support evidence workflows.

CycloneDX and SPDX are common SBOM formats. What matters operationally is whether the file can be ingested, retained, normalized, and connected to later review work.

Format support should be explicit.

Teams should confirm which CycloneDX or SPDX files their intake workflow accepts before relying on downstream review evidence.

Normalization connects format to review.

Once ingested, component data needs to become reviewable product-version inventory that can connect to CVE review and evidence history.
