Yeah, I think we have to reposition Kate a bit better. In my mind,
Kate is a generic way to align any type of text-based content with an
Ogg timeline. Subtitles and Karaoke are one type of such content. But
any other text content can be time-aligned in the exact same way with
the same codebase. Metadata is just one type of such text content. The
Kate libraries already allow for time-aligning SRT and the
Kate-format. These are just means of providing time-aligned text. Oggk
has recently also made it explicitly possible to attach arbitrary
tag/value metadata to timed events. So Kate is a lot more than just

I'm expecting that the next format that we will encode in a Kate track
is WebVTT. It can't be hard to do because Kate already supports all
the required functionality. There just isn't yet a WebVTT parser that
would chop it up for libkate to feed into Ogg. :-)
