Putting in place a serious process for tag migration will be
difficult. I suggest that a first step will be definition of an actual
schema, with version number. For example, define an actual list of
several hundred tags, with semantics, that correspond to "OSM core
1.0". Then, we could have votes on changes to the schema, with advance
notice given: "On November 1, 2011, the main database will be updated
to OSM core 1.1. Please have your editor and renderer patches ready
for this date."
Not easy, and I don't think the OSM community is at that level of
process maturity yet.

It is quite easy to use the wiki by using subpages for metadata
(semantic...) on tags (and reusing those data in the main page). e.g.
* Tag:boundary=administrative
* Tag:boundary=administrative/meta
# gathering 'per versio'n changes : e.g.
** 201104:added
** 201207:obsolete;use "Tag:boundary=admin"
* Tag:boundary=administrative/Core_201104
* Tag:boundary=administrative/subscibers e.g.
** JOSM:category:geography
** mapnik:*
With a Caterory:Core_201104 page gathering the tags
The metadata subpages can be accessed in raw format easy to parse.
Have a look to :
http://wiki.openstreetmap.org/wiki/Besan%C3%A7on/params
that is used in :
http://wiki.openstreetmap.org/wiki/Besan%C3%A7on
and other pages
Maybe it is not a standard tool in version tracking, but it remains
strait closed to the documentation. A boot could build standard tool
from it.
