   resources related to version control, such as past versions and
   working copies.

RFC 5829            Version Navigation Link Relations         April 2010

1.  Introduction

   This specification defines a set of link relation types that may be
   used on Web resources that exist in a system that supports versioning
   to navigate among the different resources available, such as past
   versions and working copies.

   These link relations are used in the AtomPub ([RFC5023]) bindings of
   the "Content Management Interoperability Services" (CMIS).  See
   Section 3.4.3.3 of [CMIS] for further information.
