I have previously asked this question here, but I was asked to post the question on this forum.
I have an
.owl file which has an entitiy something like this:
<owl:NamedIndividual rdf:about="http://example.org/kb/object_test.owl#obj_1234_pose"> <rdf:type rdf:resource="http://example.org/kb/example.owl#Transform"/> <example:quaternion rdf:datatype="http://example.org/kb/example.owl#vec4">0.0 0.0 1.0 0.0</example:quaternion> <example:translation rdf:datatype="http://www.w3.org/2001/XMLSchema#vec3">0.0 0.5 0.2</example:translation> </owl:NamedIndividual>
When I do a
prolog query (
triple is part of the framework’s query language):
triple('http://example.org/kb/object_test.owl#obj_1234_pose', 'http://example.org/kb/example.owl#translation', A).
I get the response:
type('http://www.w3.org/2001/XMLSchema#vec3','0.0 0.5 0.2').
Firstly, I do not get
type in the response when
rdf:datatype is a
string. In case of a
&xsd;string, I get the result as (for example):
0.0 0.5 0.2 Why is that so?
Secondly, is there any way to extract the value from the
type? Or do I need to treat it a string manipulation?
