Jackalope / jrf (public) (License: GPLv3 or later version) (since 2019-11-21) (hash sha1)
Libriary for reading and writing resource files: vertices, indices, meshes, images, models and scene data.
Supports reading from filesystem as well as from zip files.
It uses unique binary container format for those resources.
It is used in tool for converting popular formats like wavefront .obj file, TARGA image to this container and also used in resource loader as part of graphics framework.

It requires jlib libriary (see my user repositories) and libzip.
It is possible to remove libzip dependency.
