libburnia is a project comprised of libraries and binaries for reading, mastering, and writing optical discs. It provides libburn, a CD/DVD/BD burn library, libisofs, a manipulation library for ISO 9660 filesystems, and libisoburn, a ISO 9660 multi-session library. On top of them there is cdrskin, a cdrecord emulator, and xorriso, a all-in-one application for ISO 9660 multi-session operations which additionaly provides a limited emulation of mkisofs.
cdrkit is CD Recording Kit, a collection of applications related to creation of optical disk media on Unix platforms, from creation of the filesystems used on such media to the actual burning process. It is heavily based on the cdrtools package (partially developed and maintained by Joerg Schilling before), but is maintained independently.
