p.s - another motivation for using `total_track_dur` is that, if you ever end up trimming or slicing the audio/jams, if the trimmed section doesn't intersect with the start/end times of...

I agree it's cumbersome, but time/duration are baked into the definition of an observation: https://github.com/marl/jams/blob/255a5ee860b03cec8f889c9986e734a6393a0dbc/jams/core.py#L597-L599 I may be wrong but I believe that supporting observations both with and without time/duration...

My 2c as the person who put the "curator" field in there in the first place :) The intention was precisely for attribution. While a dataset can have many annotators...

p.s. forgot to add, in light of the above, I'd support @urinieto's proposal of making the curator field a list of `Curator`.

Do you mean something like this (sorry about quick hack):  I think this could also work, though I wonder if, given that the J is already in the shape...
