other kinds of thing have 'callSign' beyond radio broadcasts, esp. vehicles/boats and non-radio broadcast

[danbri]

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

[danbri]

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."

[danbri]

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

[danbri]

  ?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)...)

And please include person in the domain for callSign, since licensed amateur radio operators also have official callsigns (typically using the same naming scheme as e.g. US radio stations).

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.".
