I didn't see any links on the EventSchemaUpdate wiki page to real
world examples of existing sites that publish this information (even
in plain text, without any markup/classes etc.)

E.g. what event sites publish an "eventstatus"?

What event sites publish the previous date (or dates) of an event?

(n.b. I've never seen this, curious to see where you've seen this
behavior, and if not, why you think putting it in the schema will
cause sites to publish it - such prescriptive/wishful features are
rarely effective in practice.)

Why is a special eventCategory property needed?

Why not just re-use the "category" property? (also already exists in

This is an interesting use of such plurality.  Still, I have to ask
for the research here that's driving the design, e.g. URLs of real
world examples of existing sites that publish repeated events by
publishing each instance (even in plain text, without any
markup/classes etc.).

Alternatively I've seen simple descriptions like "every wednesday at
10am" (e.g. telcons) - but I agree with leaving out (seemingly)
neverending repeated events (data fidelity typically fails when
repeats occur across politically determined DST changes).

Makes sense and a good re-use of a property used the same way in
hCalendar and iCalendar.
