May 1, 2025May 2025 achievements for google/osv-scalibr: Delivered a centralized PURL generation library consolidating PURL creation for NPM, Hex, Java, Go, Windows, SPDX/CDX, DPKG, Homebrew, and filesystem/os extractors, enabling consistent, spec-compliant identifiers across ecosystems. Added chain_id to LayerDetails proto to support multi-chain contexts, enabling future multi-chain analyses. Introduced Annotator plugin type and relocated cachedir to support plugin-based extensibility. Standardized scanning workflow by centralizing ScanInput handling via scalibrfs.ScanRoot, propagated the current GitHub release version to scan results, and added a --version flag to SCALIBR. Refactored the Extractor API to remove ToPURL/Ecosystem usage in favor of Package.PURL(), and expanded extraction capabilities (FilesystemExtractors directory-based extraction; Windows extractors now declare Windows requirements). Implemented stability improvements including removing an unnecessary wrapper around baseimage.NewDefault and correcting Podman extractor's metadata field and deprecated import.
