Bibliographic references should clearly identify research documents. When referencing a baseprint, the use of a web address (URL) is insufficient. Multiple websites can contain the same baseprint, and no one website is the definitive source. Instead of referencing a web address, baseprints are referenced with an intrinsic identifier, such as a Software Heritage ID (SWHID) [@cosmo_referencing_2020] [@dicosmo:hal-01865790]. The identity of a baseprint is determined by its exact digital encoding. If a baseprint is composed of a single file, the digital encoding is a sequence of bytes. If a baseprint is composed of a directory of files, the digital encoding can be a git tree.
