Convergence on time series and events

[effigies]

It came up in a maintainers meeting today that the problem of non-neural time series is coming up repeatedly, and we should coordinate to ensure there isn't a proliferation of different solutions to similar problems.

BIDS currently has physio.tsv.gz and stim.tsv.gz formats, and the following BEPs all propose some kind of time series (regular sampling) or events (annotations or time-stamped samples):

• 009 - PET (blood.tsv)
• 012 - Functional derivatives (timeseries.tsv)
• 021 - Eye tracking (eyetrack.tsv)
• 021 - Electrophysiology derivatives (annotations.tsv)
• 029 - Virtual and physical motion data (motion.tsv)

Perhaps we can schedule a meeting in the next few weeks where we can discuss our use cases and solutions and see if there's some common ground?
