There is demand for a way of describing the structure of courses, but 
that does not mean that there is a demand for finding course structures. 
Certainly the level of demand for finding machine-readable course 
structures is less than the level of demand for finding courses. Hence I 
give it a much lower priority. Very few people will decide not to take a 
MOOC just because they cannot find a machine readable structure for it, 
so I don't see the lack of way of describing course structure as 
blocking an effort to make courses more easily discoverable.

OK, so if I understand, that sounds more like IMS Simple Sequencing, 
Learning Design, maybe the manifest of Content Packages?

I am not sure that is the same as syllabus (a list of topics to be 
studied is different from a sequence of activities on a course). 
Wouldn't the syllabus be the same for all instances of a Course? Whereas 
details of the sequencing might vary from one CourseInstance to another?

Sorry. I am still trying to understand what you want to describe and why.
If you could find concrete examples of them being shared that would help.
