RE: Course, a new dawn?

This may be a rabbit hole and I apologize for jumping in late … there does
not seem to be a way to associate courses with outcomes or competencies.

There is a mock up of Vicki's proposal (as I understand it) at
http://course.schema-course-extend-vthprop.appspot.com/Course
http://course.schema-course-extend-vthprop.appspot.com/CourseInstance

If you scroll right down to the bottom there are a couple of examples as
Google testing tool output (more or less human readable) and RDFa.

Are we happy to proceed with this as a general approach?

I am concerned that in the name of simplicity, we are losing the ability to
understand the various things a Course may be:



1. The abstract notion (e.g. "HNC Accounting").

2. A specific session of the Course (e.g. HNC Accounting taught at St
Brycedale Campus Kirkcaldy starting 2016-08-29).

3. An offer to sell access to a Course. In the online world, this is
usually a specific session.



As the examples are written, I cannot tell the difference between
definitions 1) and 2), particularly because the first example gives dates.



I think we need to move back to a model where there is:



1. Course which is a subtype of CreativeWork

2. CourseOffering (or CourseSession if Offering is too close to Offer)
 which is a subtype of Event

3. Use the "offers" property on CreativeWork and Event to allow someone to
specify an Offer to sell access to a Course or CourseSession as appropriate.

Well, that got complicated & confusing.

Richard and I had a chat this afternoon, he suggested we try something
different. Briefly, it is to try a new starting point (and I hope I have
interpreted correctly):

Do not have separate types for Course and CourseOffering.

Define Course as a subtype of both Creative Work and Event, which can be
used for both the abstract description and the concrete instances.

Define a coursePresentation property of Course to relate the concrete
instances to the abstract description when necessary. (I guess and inverse
property might useful).

When describing a concrete instance of a course, declare it to be both a
Course and an Offer. This allows the use of price, offeredBy, ApplyAction
and so on.

There is an mock-up of this at
http://course.schema-course-extend-rjwprop.appspot.com/Course If you scroll
right down to the bottom there are a couple of examples as Google testing
tool output (more or less human readable) and RDFa.

Any comments on this as a general approach? Does it make enough of a
distinction between a Course and its Sections/Presentations/Offerings for
it to be clear to people who care about such a distinction?

Don't worry too much about details of the properties that are currently in
the mock-up, that could lead more rabbit holes prematurely.
