<https://uri.etsi.org/ngsi-ld/default-context/Event> a owl:Class ;
  rdfs:label "Event" ;
  rdfs:comment "One public event: its name, its start and a link are required (owner 2026-10-22); its place as a GPS point is expected and filled from the source or the venue table, its organizer kept where the source names one, the rest kept where the source gives it." .

<https://uri.etsi.org/ngsi-ld/default-context/PointOfInterest> a owl:Class ;
  rdfs:label "PointOfInterest" ;
  rdfs:comment "One venue of the venue table (seeds/bbsk-events/venues.csv): a hall, a square, a museum where events take place, one entity per real place (table rows of one name within 50 m are one venue), its id the OpenStreetMap object of its building or a hash of its town, name and point (DM-141)." .

  rdfs:label "address" ;
  rdfs:range <https://w3id.org/linkml/Any> ;
  rdfs:comment "The postal address of the venue, field by field (Smart Data Models' common PostalAddress); `addressLocality` is the town a calendar filters on. A field the source leaves out is absent, never guessed." .

  rdfs:label "areaServed" ;
  rdfs:range xsd:string ;

  rdfs:label "audience" ;
  rdfs:range xsd:string ;

  rdfs:label "category" ;
  rdfs:range xsd:string ;
  rdfs:comment "The event's main category, one code of the platform's list of 16 (docs API/12-event-categories.md), picked by the rule table seeds/event-categories.json from the source's own word, the name or the kind of body that announced it (`music`, `sport`), else by the decision model's cached answer. A list of one, as Smart Data Models' Event writes `category`; absent while neither has named the event." .

<https://uri.etsi.org/ngsi-ld/default-context/categorySource> a owl:DatatypeProperty ;
  rdfs:label "categorySource" ;
  rdfs:range xsd:string ;
  rdfs:comment "How `category` was picked: `rule` the rule table, `model` the decision model's cached answer for an event no rule decides (scripts/events-classify.py)." .

  rdfs:label "dataProvider" ;

  rdfs:label "endDate" ;
  rdfs:range xsd:string ;
  rdfs:comment "When the event ends, written as `startDate`; for a whole-day event its last day, inclusive. Absent when the source gives no end: the calendar then shows the start alone." .

<https://uri.etsi.org/ngsi-ld/default-context/eventCategory> a owl:DatatypeProperty ;
  rdfs:label "eventCategory" ;
  rdfs:range xsd:string ;
  rdfs:comment "The kind of event in the source's own words (`koncert`, `výstava`, `šport`), kept so `category` can be traced back to it." .

  rdfs:range xsd:string ;
  rdfs:comment "How close `location` is to the venue: `source` the publisher's own point, `building` the venue's building (the address register or a venue checked against OpenStreetMap), `office` the organizer's or the town's office standing in for a venue nobody placed, `centre` the town's centre. A map draws `office` and `centre` as approximate." .

  rdfs:label "locationSource" ;
  rdfs:range xsd:string ;

  rdfs:range <https://w3id.org/linkml/Any> ;
  rdfs:comment "Who runs the event: the museum, the school, the town or the named performer, never the feed or the aggregator that announced it (that is `dataProvider`). Its name and its web site only, never a person's e-mail or phone." .

  rdfs:comment "When the event starts: an RFC 3339 instant with its offset (`2026-11-14T19:00:00+01:00`, Europe/Bratislava as the source publishes it), or a date alone (`2026-11-14`) for an event that lasts whole days." .
