Is there a format or manual of style for history and historical events?  If there is not one already I would like to draft one up.  I have been putting in entries covering the OTU years between 1116 and 1248 and am coming across a variety of formats when it comes to personalities in different settings/time periods. 
Examples:
Entries marked like [[Craig Anton Horvath]] which has a link to [[Craig Anton Horvath/Rebellion]].
Entries like [[Lucan]] where the different time periods are marked as headings.  
Entries like [[Margaret Yetrina Tukera]] where information related to a different time period is hidden with hidden/show tag of Hidden|header=Rebellion Era (Click Show to reveal) or some such.

I do not on the whole deal with the GURPS: Traveller Universe, but I am cognizant of the OTU/ATU Rebellion/No Rebellion thing. I also know that wikis can get cluttered with "almost duplicate" entries.  SO...
Is there already a manual of style with regards to History and Personalities?  If not, I would like examine further, perhaps propose one.
