Abstract
This document gives an overview of the different documents that
comprise a full solution to the YANG versioning requirements
document. The purpose of this document is to help readers understand
how the discrete parts of the YANG versioning solution fit together
during working group development of the solution documents.

1. Introduction
[I-D.ietf-netmod-yang-versioning-reqs] documents the requirements for
any solution to the YANG [RFC7950] versioning problem. In
particular, chapter 5 lists the formal requirements that a solution
requires.
The complete solution to all of the YANG versioning requirements is
comprised of five documents, each addressing different aspects of the
solution. These documents are:
1. [I-D.verdt-netmod-yang-module-versioning]
2. [I-D.verdt-netmod-yang-semver]
3. [I-D.rwilton-netmod-yang-packages]
4. [I-D.wilton-netmod-yang-ver-selection]
5. [I-D.verdt-netmod-yang-schema-comparison]
The aim of this document is to help readers understand how these
different solution documents fit together, and also which documents
contribute solutions that address particular individual requirements.
Open issues, across all of the solution documents are tracked at
<https://github.com/netmod-wg/yang-ver-dt/issues>.

2. Solution Documents
2.1. Updated YANG Module Revision Handling
In summary, [I-D.verdt-netmod-yang-module-versioning] specifies
minimal extensions and updates to the YANG language, YANG Library,
and YANG author guidelines to provide more flexible YANG module
revision handling. The intent is that these changes and extensions
could be folded into future revisions of the updated specifications.
The document provides a base solution for all requirements except Req
2.2, Req 3.1 and Req 3.2.
The extensions and changes in the document can be summarized thus:
