After spending a few weeks working on a way to streamline and simplify the data entry and delivery methods for Similie Timeline, I’ve discovered that someone else has already tackled this issue. So, long story short, we now have a fully operational javascript event xml generator that can be integrated into a variety of contexts (I’ve also been modifying the code slightly for my own purposes). So far, I haven’t found an easy solution to produce multiple, overlapping threads within a single timeline. This may ultimately require some complex ajax programming that’s out of my league. But, I’ll continue looking into it.
P.S. – I’ve also learned that the mac application Tinderbox allows you to export directly into Timeline xml files from its GUI (you have to scroll down the page a bit for the relevant post). It’s worth a look.
