I have a news system that creates news posts, and I'm considering whether it makes sense to mark up the results with the "event" seo schema from schema.org: http://schema.org/Event
The problem is, some of the news posts are about physical events, and some are about online, non-physical, discounts of certain brands/groups of shoes sold on the website.
Does it make sense to mark up an online-only, limited-time (e.g a week) sale with the Event schema? Has anyone seen that in use and being utilized anywhere? Or perhaps there's another different schema that would be more appropriate for that?
