Hi All,

I'm opening this thread (and a corresponding GitHub issue
https://github.com/schemaorg/schemaorg/issues/1361) to discuss expanding
the domain of schema:about <https://schema.org/about>. Currently, that
domain is limited to CreativeWork <https://schema.org/CreativeWork> and
CommunicateAction <https://schema.org/CommunicateAction>.

I propose that the domain be expanded to include Event and subTypes of
Event. Throwing a few quick examples out:

   - A ChildrensEvent about Harry Potter:
   http://leacockmuseum.com/festival/harry-potter-childrens-day/
   - A DanceEvent about history:
   https://govisland.com/blog/a-weekend-of-song-dance-performance-and-history
   - An EducationEvent about [chemistry, corrosion, rusting...]:
   http://www.rsc.org/eic/2016/03/corrosion-rusting-electrochemistry-demonstration
   - A ScreeningEvent about Alfred Hitchcock:
   http://minneapolis.happeningmag.com/hitchcock-festival/

A full example:
I've experimented with this idea, marking up this BusinessEvent, which
covers multiple topics:
http://edw2016.dataversity.net/ The result is visible here:
https://search.google.com/structured-data/testing-tool/u/0/?url=http://edw2016.dataversity.net/#url=http%3A%2F%2Fedw2016.dataversity.net%2F

What do folks think of this proposal? I can work up more formal examples if
there is agreement it's worth the effort.

Also, are there other types that would benefit from inheriting the about
property? For example, I can foresee a desire to describe a
schema:Organization <https://schema.org/Organization> in this manner:

The World Food Program <http://www.wfp.org/> is about:
https://en.wikipedia.org/wiki/Malnutrition

Cheers,
