From a group that is trying to curate a data set - a question about collection_time_point_relative
Related to but not the same as #504
This group has a time series (subject sampled at multiple times), but doesn't actually have a duration between visits. So it isn't "day 1", "day 30", and "day 60", it is "visit 1", "visit 2", and "visit 3". The need is to group samples that are taken at specific "visits" (e.g. on "visit 2").
I think we want something like this:
collection_time_point_reference = 'subject enrollment'
collection_time_point_relative = 2
collection_time_point_relative_unit = 'visit'
collection_time_point_relative_unit_id = 'UO:????????' - an ontology ID that represents relative time.
It seems like it might be a common use case to require an ordinal scale for this data.

It seems like one way to represent this is:
with no units?
