2) There are are several PBCore instantiation properties that apply to
the entire file like duration and tracks that we'd want prefixed with
pbcore so I think it would be odd to see:
pbcore:instantiationDuration=00:00:05.20
stream[0]/pbcore:essenceTrackType=Video
This structure does have the advantage that any tool can easily see that
the second metadata key relates to a sub-stream / sub-track etc, without
having to know anything about PBCore. That will make it easier for tools
to exclude or handle these differently in a general way.
(I can't think, off the top of my head, of another kind of thing that
might need this structure, but I'm reluctant to nail it down to being only
for PBCore if that'll cause us issues when we try to support something
very similar in future)
Any chance you could get / fake a nearly-full set of metadata keys and
value for a media file with (say) 3 streams? We can then generate pbcore
prefixed and general prefixed versions, which should hopefully make it
easier for other community members to compare and offer their input!
