A method includes determining whether the first version is an alias with respect to the second version, the alias being defined as an equivalent version of the YANG module. Based at least in part on a determination that the first version is the alias with respect to the second version, a version alias extension is inserted into a revision label of the first and/or second version. Based on a determination that the second version is backwards compatible with respect to the first version, a version backwards compatible extension is inserted into the revision label of the second version. Based at least in part on a determination that the second version is not backwards compatible with respect to the first version, a version non-backwards compatible extension is inserted into the revision label of the second version.
