RE: Historical events

As mentioned in my earlier mail, the best _theory_ (from Allen) does not distinguish between instants and intervals – recognising that if your clock is good enough even things that look instantaneous do have a finite duration. So things which the vernacular calls ‘period’ and things known as ‘events’ are on a continuum. I’m also pretty catholic in my view of ‘notableness’ – if it is notable enough for someone to give it a name, then that’s enough.

I’m aware that schema.org is not theory-based, but theory can sometimes clarify.

Anthony,

I’m not following your logic here.  I don’t see a Period (of time from a start time/date to an end date/time) as an event.

That definitely works, but only if some definition of Period was agreed on.

The property periodEventOccurred would be a subproperty of superEvent in any case:

superEvent
    periodEventOccurred

So you could describe the same information using the existing term right?

The Black Death
    superEvent: The Middle Ages

Using a Period Type I would suggest a cleaner alternative way of saying an event occurred during a period would be like this:

{
"@context": "http://schema.org",
"@type": "Event",
"name": "The Black Death",
"Description": "A pandemic that spread throughout Europe",
"periodEventOccured": {
"@type": "Period",
"name": "The Middle Ages",
"approximateStartDate": "400AD",
"approximateEndDate":"1500AD"
}
}

I was referencing the development version of Schema, I should probably reference production, sorry Roger:

  *   https://schema.org/subEvent

  *   https://schema.org/superEvent

To say some event happened during the Iron Age for example:

Invention of iron plow
    superEvent: Iron Age

The google Cloud host is really slow and I think the 404 is a result of something loading too slowly. I could probably publish this more reliably on my own website! I generally just wait a bit and reload the page. Sorry about that.

Isn't it already modeled by these properties?:

  *   https://webschemas.org/subEvent

  *   https://webschemas.org/superEvent

Events can exist in part-whole hierarchies, aren't named periods just events high in these hierarchies?
