+The FreeBSD Software Bill of Materials (SBOM) effort has been continued during Q2 2026.
+This quarter’s focus has been reviewing and updating pkg-config [.filename]#.pc# files and adding SPDX-License-Identifier to third-party projects included in the FreeBSD source.
+This effort will be continued in Q3.
+
+As said, most of the quarter’s work has been dedicated to polishing pkg-config [.filename]#.pc#, as these files are needed when generating SPDX 2.2 and SPDX Lite 3.0.1-compatible SBOM files.
+During this year Pierre Pronchery has been adding other crucial parts like pkgconf to the FreeBSD source.
+Currently, the biggest effort lead by him on the tooling side is the review of the SBOM generation part of the build, which holds [.filename]#.pc# as part of the review.
+When the review is ready and the source is added to FreeBSD, SBOMs can be created during the building process.
+
+Besides work on [.filename]#.pc#, there has also been polishing of The FreeBSD Lua Tools for SBOM, which have been used to create the current set of [.filename]#.pc# files and can be used for future updates.
+These scripts are still somewhat raw and complicated to use but are now in much better shape than before, and there is documentation on how to use them.
+
+Adding SPDX-License-Identifier to third-party repositories is also a work in progress and will proceed in an order that aligns with project maintainers’ preferences.
+Why are license identifiers being added to third-party projects?
+There is no simple answer to this question, but the closest explanation is that machine-readable license identifiers help maintain SBOM information in the future.
+
+If you want to help with this effort:
+
+* Review [.filename]#.pc# files in Phabricator as part of the "Generate SBOM files as part of the build" review.
+* Assist in reviewing the pkgconf 3.0 import to the FreeBSD source.
