dbpprop:showName can end up as xsd:integer and lose information

[josephw]

For a television show, I would expect dbpprop:showName to be identical to foaf:name. However, in the case of '30 Rock', it's getting treated as a numeric '30' instead:

SELECT ?name, ?showName
WHERE {
  <http://dbpedia.org/resource/30_Rock> foaf:name ?name ;
                                        dbpprop:showName ?showName .
}

Gives:

name	showName
"30 Rock"@en	30
