+The FreeBSD Software Bill of Materials (SBOM) project started in 2025 and continued in 2026. Work in 2026 has been more about EU Cyber Resilience Act (CRA) and focus has shifted to delivering a framework for FreeBSD source.
+
+First quarter of 2026 delivered SBOM work in three categories:
+* Pkgconf upstream work especially with spdxtool-tool which is for creating SPDX Lite 3.0.1 JSON-LD SBOMs from [.filename]#.pc#-files. Several missing features have been added and have been under active work by pkgconf contributors. The tool is now nearly compatible with SPDX Lite 3.0.1 requirements and is ready for general use. Besides that there is an effort to import pkgconf as part of the FreeBSD source, lead by Pierre Pronchery.
+* Adding missing SPDX-License-Identifier to files under FreeBSD source [.filename]#bin#, [.filename]#sbin#, [.filename]#usr.bin# and [.filename]#usr.sbin# -directories.
+* Creating [.filename]#.pc#-files for SBOM. First patch should be start to land on 2026Q2. They are from [.filename]#bin#.
+
+If you want to help with this effort:
+
+* Verify SPDX-License-Identifier licenses are correct and help upstreaming files
+* Verify [.filename]#.pc# for that information which they hold is correct and help upstreaming files to git
+* Help reviewing pkgconf import to FreeBSD source
