[Mediawiki-l] Bot and "permanent links"

[fred]

Hi folks,

I'm currently pushing my company to adopt mediawiki as our main collaborative 
working tool.
I'm looking for a way to automaticaly create an article containing a list of 
permanent links pointing to specific versions of articles. It could be a 
category but this category should be "frozen"; the category should list the 
articles versions frozen at time T.

In short, I'm trying to "tag" (as in cvs or subversion) a list of articles.

Is it feasible with mediawiki? Maybe using some Bots?

Thanks,

Fred
