Hello All,

Good to be in this group !! I am a PhD student of ICT at Swinburne University of Technology, Australia. I am particularly interested in Events/Situations. It seems there is no "Situation" concept in schema.org. There is an Event concept with mostly cultural events (Festival, FoodEvent,etc) in specific types (see http://schema.org/Event). I wish there were natural or other events included in schema.org.

Is anyone else working on events? What about situations? Does "Situation" need a separate concept or can it be somehow linked to event?

Hi Zaman,

Can you elaborate and give some examples on what kind of data would be captured or presented for a "Situation" ?

Hi Thad,

Consider there is an accident on a major highway probably an instance of TrafficSituation or an Earthquake.

Currently you can use the "about" property that is in pending on the Event Type to classify it or narrow the scope of an Event. An alternative is by using an MTE, multi-typed entity or the "additionalType" property.

{

"@context": "http://schema.org",

"@type": "Event",

"name": "Gridlock near the Hi-Dive because of goats",

"about": "Traffic",

"location": {

"@type": "Place",

"address": {

"@type": "PostalAddress",

"addressLocality": "Denver",

"addressRegion": "CO",

"postalCode": "80209",

"streetAddress": "7 S. Broadway"

},

"name": "The Hi-Dive"

},

"startDate": "2013-09-14T21:30"

}

Sometimes Sub-Typing is the right way forward, sometimes adding useful Properties makes a Type cover even more domains and addresses broader / narrower classifications to be easily handled.

To your cause and point however... yeah, the world has those types already:

A TrafficEvent

A NaturalEvent

http://dbpedia.org/ontology/NaturalEvent

A SocietalEvent - an event that is clearly different from strictly personal events

http://dbpedia.org/ontology/SocietalEvent

Hi Thad,

That's pretty useful. Thanks. So what would be the @context for a type SocietalEvent defined in dbpedia.

Just use additionalType ... it takes a URL to give "additional" context

{

"@context": "http://schema.org",

"@type": "Event",

"additionalType": "http://dbpedia.org/ontology/SocietalEvent",

"name": "Gridlock near the Hi-Dive because of goats, who are now warring in a bloodbath",

"about": "War !!! between the goats",

"location": {

"@type": "Place",

"address": {

"@type": "PostalAddress",

"addressLocality": "Denver",

"addressRegion": "CO",

"postalCode": "80209",

"streetAddress": "7 S. Broadway"

},

"name": "The Hi-Dive"

},

"startDate": "2013-09-14T21:30"

}

Hi Zaman,

I'm also working on with these concepts (event, situation, event type, situation type, participation, situoid, etc) within a foundational ontolog in my PhD, which I'm finishing this year. I recommend these 2 papers I wrote:

https://www.semanticscholar.org/paper/Towards-ontology-driven-situation-aware-disaster-Moreira-Pires/4cd3cc99177049625b14a0aad1c20748de8e2fa2

http://www.scitepress.org/Papers/2017/62089/62089.pdf

I'm also interested in how to bring these concepts to schema.org. Let me know if you want a closer contact for discussions on this topic.
