Re: Historical events

This will work just fine, if it's considered valid. I just registered with Bing and tried its microdata testing tool and that use of Event is fine according to that tool. I was a bit confused because Google's Structured Data Testing Tool shows 2 errors and 5 warnings for the following markup:

the <span itemscope itemtype="http://schema.org/Event"><span itemprop="name">Trojan war</span></span>

It says "A value for the location field is required." and "A value for the startDate field is required."

Thank you, Thad.

Allison and Roger... see examples below.  Yes, you can still use Event.  When you don't have a startDate or endDate, then just leave them excluded.  The use of additionalType and referencing other ontologies or Wikidata is quite useful and a generally accepted best practice when you need to easily subtype things that Schema.org<http://Schema.org> has only general types available.

{
  "@context": "http://schema.org<http://schema.org/>",
  "@type": "Event",
  "sameAs": "https://www.wikidata.org/wiki/Q327052",
  "additionalType": "https://www.wikidata.org/wiki/Q15815670",
  "name": "Battle of Aachen",
  "startDate": "2 October 1944",
  "description": "major conflict during World War II",
  "endDate": "21 October 1944"
}

{
  "@context": "http://schema.org<http://schema.org/>",
  "@type": "Event",
  "sameAs": "https://www.wikidata.org/wiki/Q11761",
  "additionalType": "https://www.wikidata.org/wiki/Q15401699",
  "name": "Bronze Age",
  "description": "prehistoric period",
  "about": "Historical Event"
}

Any other questions ?
