Analyzing data module versions for aliases and backwards compatibility

A non-transitory computer-readable medium storing instructions that, when executed, causes a processor to perform operations, comprising:

• comparing a first version of a YANG module stored in a YANG library of a server computer with a second version of the YANG module, the first version being included in a branch of a parent version that is an earlier revision relative to the second version;
• 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;
• and
• based at least in part on a determination that the first version is the alias with respect to the second version, inserting a version alias extension into a revision label of the second version.

A server comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• comparing a first version of a YANG module stored in a YANG library of a server computer with a second version of the YANG module, the first version being included in a branch of a parent version that is an earlier revision relative to the second version;
• 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, inserting a version alias extension into a revision label of the second version;
• determining whether the second version is backwards compatible with respect to the first version;
• and
• based at least in part on a determination that the second version is backwards compatible with respect to the first version, inserting a version backwards compatible extension into the revision label of the second version;
• and
• based at least in part on a determination that the second version is not backwards compatible with respect to the first version, inserting a version non-backwards compatible extension into the revision label of the second version.
