SELECT ?property ?object ?value
This works
WHERE
{?subject ?property ?object.
?property a owl:ObjectProperty.
?object rdfs:label ?value}
This works also
WHERE {
{?subject ?property ?object.
?property a owl:DataProperty}
But the union only returns object properties (everything before the
union) in this case
WHERE {
{?subject ?property ?object.
?property a owl:ObjectProperty.
?object rdfs:label ?value}
UNION
{?subject ?property ?object.
?property a owl:DataProperty} }
And only data properties (before the union) in this case
WHERE {
{?subject ?property ?object.
?property a owl:DataProperty}
UNION
{?subject ?property ?object.
?property a owl:ObjectProperty.
?object rdfs:label ?value} }
While I would like to have both.
What am I missing?
