– "I figured out to use the ISO formatting for the dates, but now am stuck on what to do when the date is BC. My research says that you just put a - before the year, but the date did not register on the timeline. Any ideas."

My email for/to Ronan:
– ""
I joined to ask RonanKER a question - but I found that his talk page was protected - "The action you have requested is limited to users in the group Sysops."(http://simile-widgets.org/w/index.php?title=User_talk:RonanKER&action=edit)

Would you mind forwarding this question on to him please, if he's the most appropriate person? (I'm not sure if my message here will get through, http://ronan-kerdudou.fr/cv/contact/ )

What is the feasibility of handling BC dates in the MIT Simile libraries?

I've found these clues,

Please see this discussion and page for the context,

Many thanks for your help.

Great work on MIT SIMILIE!
