Then we might as well just use a wiki-page on Redcap, right?
If we want to turn 'old edition stuff' on af off, that can be done too, but then I'd probably need direct access to the HTML, so not as easy.
I made a webapp to manage an arsmagica timeline a few months ago. It is an early build, as I worked on other things, but it can be improved easily. Let me know if you want to try, but I have a few things to change to make it ready to use.
Currently an event on the timeline has the following attributes :
Historical date (ex 01/01/1220)
Book reference (ex House of hermes true lineage)
Other reference (could be an url)
Organization (ex Order of Hermes)
Weight (1-10, 1 being the most important, 10 a very minor one)
As the 5th edition timeline doesn't necessarily agree with earlier versions of the canon, you might want a flag for each entry noting whether they are real world historical, 5e canon, or deprecated pre-5e events. That would allow for future filtering of the view, hiding the non-canon entries or historical events as the user desired.
Also, the 10 point scale for weight seems too much. Users would never agree on whether a given entry should be a 3 or a 4, maybe a 5. A four or five point weighting system would serve better, you don't want more choices than a user would want to see (or bother to remember) as color codes.
To the kind author of the original timeline, would it be possible to simply post the file somewhere freely accessible? There's clearly enough interest that sending individual copies in response to private messages will cease being fun.
The regional tribunals already existed in 865. What was decided in 865 was a formal establishment of their boundaries and names.
Looking at the timeline in Lion and the Lily, it was decided at the Grand Tribunal in 832 that the Grand Tribunal would meet every 33 years, and the regional tribunals every 7 years - strongly suggesting that there existed regional tribunals at that point in time.
According to HoH:TL, Bonisagus "was last seen at the regular Thebes Tribunal meeting of 836" - which means that the Thebes tribunal must have existed as a regional tribunal at that point in time.
According to GotF p15-16, the regional tribunals were established in 773, and in 865 they became more formally defined with boundaries.
Tmk there were several Tribunals that were defined - with their boundaries - only in 865: the Theban Tribunal (including Coeris 848 subdued in the Sundering - see e.g. HoH:TL p.144), the Britannian Tribunal (including the later Hibernian Tribunal and the Bretagne, fully independent from the Franks since about 851), and the Lotharingian Tribunal (following the treaty of Prüm 855).
This does not imply, that between 773 and 865 there were no regional Tribunals in charge in these areas, with less defined and typically changing boundaries of jurisdiction.
There were soon after 773 early smaller regional Tribunals. E. g. Val Negra with 3 other covenants already founded the Val Negra Tribunal (F&F p.39, 135) in 774.
I thought we had established somewhere that by 773 there were four regional Tribunals that the redcaps served, which roughly corresponded to the four regions that the Tenentes Occultorum line of Bonisagus magi serve, and which were associated with the greatest covenants in the area: Branugurix (spring), Val-Negra (summer), Durenmar (autumn), and Coeris (winter). Also, I thought we had also established that initially Verdi was part of the Val-Negra tribunal. However, I don’t see any explicit references to that information now that I look for it.
