[sidestepping any consideration of what is a "course" and what is 
"course content"]

One thing to bear in mind is that in schema.org Creative Works and 
Events are distinct types of thing. LRMI defines properties that are 
available for Creative Works and subtypes thereof. So using Event start 
and end dates along with LRMI properties would require that an item has 
two itemtypes. That seems to be legal for microdata (now, it wasn't 
always)[1] -- anyone know how well it is supported for schema.org?

If you're interested in ontologies for advertising courses, I would 
suggest looking at XCRI-CAP http://www.xcri.co.uk/ or other variants of 
CEN MLO-AD http://www.cen-ltso.net/Main.aspx?put=1042
--it may be possible to map this to schema.org + some extensions.


1. See http://www.w3.org/TR/microdata/#items
