Re: CourseInstance : MaximumCapacity ?

A draft of the Common Education Data Standards (CEDS) version 6 was released for public comment today. It includes a draft data element definition for "Course Section Maximum Capacity".
The public comment period is open until May 4th. Here is the link to review and comment:

Hello all.
I think I can see a place for both the status (open/full etc.) and the size of the course instance. I think it does make a difference to know whether you will be taught in a small group (~10) or a massive cohort (~10,000).

It also strikes me that neither of these are specific to course instances, i.e. they would apply to any type of Event. I don't see anything under Event at the moment which fits the bill.  There is which can be used for showing whether the event is cancelled, postponed, rescheduled or scheduled: close but not the the right values. Other than that there is, as part of Offer, which includes SoldOut, but seems more geared to physical items. I don't see anything for event capacity except maybe the property of Offer. 

I am inclined to think that we need one new property eventCapacity (or just capacity if it is to be specific to courses), and an extension to

* eventCapacity
* Offer.inventoryLevel* Offer.availability < ItemAvailability >* Offer.availabilityStarts* Offer.availabilityEnds
* waitlist < WaitList([ (datetime, Person, status) ]) >* waitlistLength < Number >

We have used/displayed course instance status values of:

open (applications accepted, course instance not reached maximum capacity)
full (course instance has reached maximum, no further applications accepted)
waiting list (places available only if others drop out, which was reasonably common, applications still accepted)
closed (no applications accepted, existing applications voided, which I think happened if course target numbers for viability were not reached)

Perhaps from a user (applicant, searcher) viewpoint, it is not the numerical value, but the application status of the course instance that is most significant?

We did have the notion of showing a ‘fullness’ gauge, so that people might have more information to decide whether to apply now or decide later, which would have been based on a numerical calculation, but never put this into practice.

Does the number of fellow students have a particular value to course instance applicants beyond this?

A member of the CEDS community suggested a new element for the capacity of a CourseInstance. I’m wondering if there is value for this in schema and I so where it would go.

Course Section Maximum Capacity — The maximum number of students the Course Section Instance can maintain.
