Hello all,
I am using TopBraid Composer 4.2.0 Free Edition, installed using these
instructions: http://www.topquadrant.com/products/TB_EUM.html
I have created a magic property, let's call it :returnAB, that has
spin:constraint sp:arg and a spin:body like this:
SELECT ?a ?b
WHERE {
SERVICE <http://example.org/sparql> {
?thing :isLinkedTo *?arg* .
?thing :propertyA ?a .
?thing :propertyB ?b .
}
}
When I use this magic property in a SPARQL query in the TBC query editor
like this:
SELECT ?a ?b
WHERE {
<http://example.org/specificResource> :returnAB (?a ?b) .
}
it returns ALL ?a ?b for ALL resources, even though I restricted my query
to the URI <http://example.org/specificResource>.
When I copy the SPARQL query from the spin:body of :returnAB, restrict it
to <http://example.org/specificResource>, and execute it using the query
editor in TBC as follows:
SELECT ?a ?b
WHERE {
SERVICE <http://example.org/sparql> {
?thing :isLinkedTo <http://example.org/specificResource> .
?thing :propertyA ?a .
?thing :propertyB ?b .
}
}
I get the expected results just for things linked to <
http://example.org/specificResource>.
Why is the magic property not restricting ?a ?b results when a resource URI
is specified?
Thanks,
Alison
