I hadn't thought of your last two examples, so I'd say we're in the 
data-collection phase.

Metadata is always open-ended, so I think we should define an 
extensible mechanism and pick some simple categories to standardize for 
initial interoperability.

I would add title, author, date, translator, etc. labels.

I really like the timecode offset suggestion. How would software handle 
this? Does the CMS Re-timestamp the webvtt file when it's deployed in 
conjunction with that video? Are videos referenced by string? SHA-1? 
Would user agents parse and apply this on the fly?
