Re: schema-course-extend: time required or duration of the course

 blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; }  
With both the timeRequired (HH:MM) and duration, the hours per week could be calculated. So, I think the 2 properties are sufficient.

Hello all,

we have a requirement to  identify the typical learning time of a course 
comes from the use case of someone wanting to refine a search according 
to the amount of time required to complete a course. This may be the 
total duration of the course (i.e. the time elapsed between start and 
end of the course) or the estimated amount of time that the student will 
be required to spend working on the course. The latter would seem to be 
a property of the Course while the latter might vary between Course 
Instances--it's quite common that the same course is offered in a long 
form (e.g. part time) or in a shorter "accelerated" format.

We can use schema.org/duration for the time elapsed between start and 
end of a Course Instance (inherited from Event)

We can use schema.org/timeRequired for the typical time it takes to work 
through the Course (inherited from Creative Work)

More details and example at 
https://www.w3.org/community/schema-course-extend/wiki/The_typical_learning_time_or_duration_of_the_course

Is this sufficient? Would a property along the lines of time required 
per week be more useful than the total time required?


One note on that example: the Duration type seems to allow one to 
describe a the timeRequired (it inherits description property). I've 
shown this, but I am not at all sure that it is a good idea!
