Re: Historical events

Hear, hear! It does seem intended for commercial applications right now—but maybe because that’s where the most significant uptake has been? How does one go about making proposals for this kind of extension? I also came across a reference to the BBC intending to use this vocabulary for historical events but that too was several years ago.

Hi, all:

 I’ve just joined the Community Group because I’ve started consulting for the American Battlefield Trust (https://www.battlefields.org) and anticipate wanting the same thing Allison is looking for, to mark up Civil War battles, etc., so I thought I’d join the chorus.

While a grand model of temporality like OWL-Time may be useful to the semantic Web folks, my impression is that schema.org<http://schema.org> is supposed to be more pragmatic.  In this case, too pragmatic; the notion of Event supported here is the one defined by the OED as “A planned or scheduled (public or social) occasion,” because search engines want to highlight these (often commercial and hence monetized via advertising) events.  Events in the OED sense of “something that happens or takes place, esp. something significant or noteworthy; an incident, an occurrence” are not modeled.  Extending the present Event schema to encompass this meaning is not a solution.  Ideally, Event should be made more abstract and the current schema should become a subclass (e.g., ScheduledEvent).

I’m guessing there’s massive inertia militating against that.  So, as a newcomer, I’d like to ask if it’s even something worth discussing here.  More broadly: what is ontological scope of the schema.org<http://schema.org> effort?  It appears that the creation and consumption of media, online publishing, travel, tourism, e-commerce and related activities in the here and now are well catered for, but the representation of knowledge, not so much.  Are requests like Allison’s considered out-of-band?

As an aside, I was unaware of historical-data.org<http://historical-data.org>; it looks like someone, rather than joining the present effort, decided to attempt to extend existing schema developed here to suit their needs (and mimic the schema.org<http://schema.org> site while at it), giving up after nine months.  There’s nothing there I’d want to use; they extended CreativeWork to HistoricalRecord, and relied on the existing Event schema (insufficient, for the reasons outlined above) to capture the historical event of interest.

best regards,

Roger

Thank you Manolis! I guess the question might be put this way: how to mark an event that occurs in the past or doesn’t have a specific time associated with it as an “Event” using Schema.org<http://schema.org/> vocabulary. Does a historical event need a new/different type, like http://schema.org/LiteraryEvent or http://schema.org/SportsEvent. Is there any development in this direction?

Hi Alison,
perhaps the closest to what you want is the
recent Time Ontology proposed in the context of a W3C/OGC
spatial data on the web working group. Please see

Thank you. I know about https://schema.org/Date, which I use for actual
dates. I was wondering specifically about events, and tried marking
historical events as events but that generated errors in the validator
because I didn’t have a time and location marked up. Event seems intended
for commercial events held in venues that one can buy tickets for. It
doesn’t seem to really fit for something that happened sometime in the
late Bronze Age—or  the Plague in London 1665-1666. It would be nice to be
able to specify that information because then I could select all
historical events in any particular text.

You can use https://schema.org/Date for various properties that are dates,
and currently it says it is "an ISO 8601 date". Which, given the proposed
update to that standard, **might** mean you can use an uncertain year
range. (I don't have a copy of the document, so I am going on the Library
of Congress syntax which I think got modified...)

e.g. [-1400?~..-1200?~]/[-1400?~..-1200?~]

In HTML you could also use a time element to provide the named period "The
Trojan War".


It is a repeated question because the Web platform generally does not have
a very useful answer :(

Hello,

I’ve been looking around for some way to markup historical events, for
example “the Trojan War.” It seems there were initiatives around 2012 or
so (http://historical-data.org<http://historical-data.org/>;
http://historical-data-schema.blogspot.ca/) that seem to have stalled. I’m
new to this group, so apologies if I’m asking something that is
repetitive.

All the best,
Allison
