RE: Historical events

For overall consistency, perhaps we could use Allen’s terminology for interval relations –

Subject: Re: Historical events

Maybe:
'Process' : Event subtype.
Process :startingEvent Event (causal relationship?);
Process :endingEvent Event;
Event :occursIn Process (property range).

This could allow for sub-process / events, overlapping processes / events, order / causal relationship of processes / events modelling or inference?

Look, I'm no temporal expert or anything, but maybe the problem is in English it could be a continuum from "event" to "period" as the interval of time being named gets longer, with no clear boundary.

    Mike's birthday party - an event
    The Middle Ages - a period

Because from a data modeling point of view they're the same (at least as far as my modeling knowledge goes).

So an unpopular solution I'm guessing would be to rename the type to EventOrPeriod.

So your previous example:

    The Black Death
        superEventOrPeriod: The Middle Ages

People's ideas?

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?
