From: Stefano Tondo <[email protected]> Add hasConcludedLicense relationship to SBOM packages with support for manual license conclusion override via SPDX_CONCLUDED_LICENSE variable.
The concluded license represents the license determination after manual or external license analysis. This should be set manually in recipes or layers when: 1. Manual license review identifies differences from the declared LICENSE 2. External license scanning tools detect additional license information 3. Legal review concludes a different license applies The hasConcludedLicense relationship is ONLY added to the SBOM when SPDX_CONCLUDED_LICENSE is explicitly set. When unset or empty, no concluded license is included in the SBOM, correctly indicating that no license analysis was performed (per SPDX semantics). When differences from the declared LICENSE are found, users should: 1. Preferably: Correct the LICENSE field in the recipe and contribute the fix upstream to OpenEmbedded 2. Alternatively: Set SPDX_CONCLUDED_LICENSE locally in your layer when upstream contribution is not immediately possible or when the license conclusion is environment-specific This variable allows tracking license analysis results in the SBOM while maintaining the recipe LICENSE field for build system compatibility. The variable is initialized in spdx-common.bbclass with comprehensive documentation explaining its purpose, usage guidelines, and examples. Example usage in recipe or layer: SPDX_CONCLUDED_LICENSE = "MIT & Apache-2.0" Signed-off-by: Stefano Tondo <[email protected]> --- meta/classes/spdx-common.bbclass | 14 ++++++++++++++ meta/lib/oe/spdx30_tasks.py | 18 ++++++++++++++++++ 2 files changed, 32 insertions(+) diff --git a/meta/classes/spdx-common.bbclass b/meta/classes/spdx-common.bbclass index ca0416d1c7..504e6fba45 100644 --- a/meta/classes/spdx-common.bbclass +++ b/meta/classes/spdx-common.bbclass @@ -36,6 +36,20 @@ SPDX_LICENSES ??= "${COREBASE}/meta/files/spdx-licenses.json" SPDX_CUSTOM_ANNOTATION_VARS ??= "" +SPDX_CONCLUDED_LICENSE ??= "" +SPDX_CONCLUDED_LICENSE[doc] = "The license concluded by manual or external \ + license analysis.
