Large orders, as a FILTER — outside OWL 2 RL

The same answer in both regimes: this query asks only for what was written.

The query

# The SPARQL equivalent of the defined class onto:LargeOrder.
# Useful because the OWL 2 RL profile does not cover datatype restrictions:
# with owlrl the classification never appears; this query answers anyway.
PREFIX xsd:  <http://www.w3.org/2001/XMLSchema#>
PREFIX onto: <https://data.csoares.me/onto#>

SELECT ?order ?totalCents
WHERE {
  ?order a onto:Order ;
         onto:totalCents ?totalCents .
  # 50000 cents = 500 euros, the threshold in the class definition
  FILTER (?totalCents >= 50000)
}
ORDER BY DESC(?totalCents)
