Event

Description
An event happening at a certain time at a certain location. Therefore it looks like an event must specify one of the startDate, endDate and possible location and duration.

In addition, while the most subtypes does not define new properties, UserInteraction is a special kind of event intended to annotate user activities on the page.

Example
While Schema.org does not distinguish abstract types from concrete one we would encourage publishers to consider subtypes of Event for their markup. Please check for examples on the subtypes pages.
