Can you give an example of this? It may be better to model these as
different types rather than trying to mash them together. The programmes
type could then include the modules.

Point taken. I think it is important to designate MOOCs from other courses.
I tend to prefer using subclasses instead of booleans as it is easier to
expand a subclass to include properties I missed the first time around.

The integration with Event is one of the places that needs refining.

Good point. I'll update the description to be more inclusive of other
educational systems.

I'll update the document to include some of the sites I was using for
reference, but they were:

Coursera (The example came from
https://www.coursera.org/course/datascitoolbox)
MIT course catalog (http://student.mit.edu/catalog/m6a.html)
Stanford course catalog (https://explorecourses.stanford.edu)
edX (https://www.edx.org/)
Cambridge Center for Adult Education (http://www.ccae.org/)
