Add a "LearningResource" type that can indicate learning-oriented educational content (and events, products...) #1401
Description
In LRMI and related circles there has been much discussion of whether we should have a "learning resource" type. There are good arguments for this and against this, but here we capture the idea sufficiently to surface this debate (a) within our schema.org issue tracker and (b) in the "pending" section of schema.org.
An argument against LearningResource is that anything can be used to learn from. A counter-argument is that, while this is the case, there are still many events (c.f. existing EducationEvent) and pieces of content (e.g. textbooks, course materials, c.f. Course and CourseInstance) which are quite explicitly oriented towards learning.
Another argument against is that, with "learning-oriented-ness" being somewhat vague, such a term would be particularly prone to abuse or incorrect usage. Would it be wrong for every http://schema.org/NewsArticle on a site being also described as a LearningResource?
I (danbri@) propose we continue the discussion in the context of a specific "pending" proposal here.
