It is most associated with desktop and firmware metadata workflows where large XML files need repeated lookups. ### Historique du projet Richard Hughes' README frames the project around the cost of parsing XML and the inability to mmap normal XML strings directly. libxmlb converts XML into a structured binary format with a deduplicated string table and NUL-terminated strings, trading compactness for fast queries and near zero-copy access. The first visible 0.1.0 GitHub tag points to a commit dated 2018-10-04. The design is intentionally narrow: it implements only a subset of XPath and ships xb-tool for compiling and querying binary XML. ### Historique d'adoption libxmlb became useful in Linux desktop plumbing because projects such as AppStream and fwupd deal in large XML metadata collections. The same maintainer ecosystem around GNOME, fwupd, and LVFS made the binary metadata cache a practical dependency for package and firmware tooling. ### Modes d'utilisation Typical usage is to compile XML metadata into an .xmlb file and query it with xb-tool or through the library API. It is a cache/query accelerator, not a general-purpose XML replacement. ### Pourquoi les passionnés de paquets s'y intéressent libxmlb matters to package nerds because it sits where package metadata, desktop app metadata, and firmware metadata meet performance constraints. It turns text metadata into a binary cache that package managers and desktop software centers can query cheaply. ### Chronologie - 2018: The 0.1.0 tag points to a commit dated 2018-10-04. - 2019: AppStream discussions describe LVFS and fwupd as using AppStream metadata for firmware metadata. - 2020s: libxmlb is packaged across Linux distributions and Homebrew as xb-tool and the libxmlb library. ### Related projects - fwupd, LVFS, AppStream, GNOME Software, and other metadata-heavy desktop tools are the neighboring ecosystem. libxml2 remains the broader XML library; libxmlb is the binary metadata cache layer. ### Sources - - - - ## Notes de sécurité Aucun manifest local de gestion des secrets correspondant n'a été trouvé pour libxmlb.
