Ok, now I got it! Thank you very much, guys!
This is really cool. There even is support for i18n:
SELECT ?meltingPoint
WHERE {
?s rdfs:label "Nikotin"@de .
{ ?s <http://dbpedia.org/property/meltingPoint> ?meltingPoint }
UNION
{ ?s <http://dbpedia.org/ontology/meltingPoint> ?meltingPoint }
}
Just two final questions:
- This query [1] returns two melting point information about nicotine:
"-79"
-79
is there any possibility to convert the string data to integer?
- What about the unit here (°C/°F/°R/K)? Is there a convention about
temperatures and other units or is it possible that this may vary from resource
to resource?
Cheers,
Manuel
