Hello all, I asked for comments on the use cases, scope description and definition of an educational course [1]. There have been some suggested new use cases and clarification of the scope with respect to aggregations of courses. I have updated the pages on the wiki accordingly. Nudge me if I have forgotten anything or not captured your meaning. If you have any other comment please add them to that thread, but the general shape seems uncontroversial so I would like to start a couple of new discussion threads for how to meet requirements arising from the use cases. The first of these is around the modelling of courses and course offerings. This is tricky. There have been discussions in a couple of places at least: on Vicki's Google doc proposal [2] and Wes's pull request [3]. Consensus seems limited at the moment to - we need a schema.org type: Course - there are abstract and concrete aspects of courses, i.e. the (abstract ) thing that is offered year after year and instantiations of it that run between set dates and at set locations (on- or offline) Open for discussion: - should Course be a subtype of Intangible or CreativeWork - is there a need for a separate type for the instantiation? --if there is need, can we agree to call it a CourseOffering? I propose that we continue the discussion here, but in order to make progress pending an outcome to that discussion (and in the hope of informing the discussion with real world examples) we try the following: - work with a model that has two new types Course and CourseOffering - we do not assume any parent for these types yet, but we do try to meet requirements by drawing in properties from other types already in schema.org rather than create new ones. For example, if we want to know what a course is about we use the existing 'about' property form CreativeWork, if we want to know when a CourseOffering runs we use might find something in Event. At the end of the process we will know what schema type a Course and CourseOffering most looks like, which would be one factor in deciding what it should be a subtype of. We will also know whether they look substantially different. Do you think that will work?
