Currently,

  • We have a sub-type of BroadcastService called RadioBroadcastService.
  • callSign lists RadioBroadcastService as a type where it is expected.

https://schema.org/callSign

I propose we expand the domain to also anticipate BroadcastService and Vehicle

For examples see Wikidata

SELECT DISTINCT ?x ?tLabel WHERE { 
  ?x wdt:P2317 ?cs.
  ?x wdt:P31 ?t .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" }
}
ORDER BY ?tLabel

Text would need adapting, e.g. from "The official callsign for the radio broadcast." to "An official callsign for something, e.g. a radio broadcast, shipping boat etc."

This could also be documented as a sub-property of /identifier

  ?x wdt:P2317 ?cs.
  ?t wdt:P279 ?t2 .
  ?x wdt:P31 ?t .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" }
}
ORDER BY ?tLabel``` 

... shows more detail on the types in query.wikidata.org (could add [counts](https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries#Counting)...)

Good point @mfhepp - let's do that. Also @vholland provides an example of a non-radio broadcast service: "call signs are also used for television. So for example, WQED is the call sign for the PBS affiliate in Pittsburgh.".
