Metadata is already a catch-all. I think we first need to analyse what
exact needs / use cases we have before making a decision.

We should then consider asking for a @kind=annotation and specify this
use case some further. Also JSON may not necessarily the best solution
for this use case. We should experiment with JavaScript first. This
way we can identify the best possible solution.

Yes, WebVTT is designed to be a general container for
time-synchronized data. But as I said: we should analyse the use cases
in more detail and come up with better means of semantically labelling
the included data than by format.

Very much so!
