[Mediawiki-l] "Aging" of documents/articles

[Dirk Westfal]

Hi all,

i`m looking for a way to implement an "aging" mechanism for documents/articles 
to indicate the assumed reliability of the content as part of a quality 
management process:

- a new document/article has the 'reliability' status 'green'
- after a three months without changes it turns to 'yellow' and after half an 
year to 'red' and has to be 'verified'.  

I`m thinking about using the 'talkpage' for this process and now i`m looking 
for the neccessary hooks to set this up. 

My current ideas are to either:
a) dynamic: search for a 'signature' containing a timestamp on the talkpage 
for each document/article and show the appropiate status each time the 
document/article is shown.
 
b)static: use a bot like pybot to do nightly checks (eg, using 
special:ancientpages) and change a template on all documents/articles where 
appropiate. 
(btw: anyone using pybot or another bot for an intranet wiki? can`t get it to 
work :( )

Are there better ways to do this? Has someone perhaps already implemented a 
similar solution?

many thanks,
dwe
