OK, I've been playing with this all day to no avail.
Going back to my <Environment> example, I have tried using the
following 2 xml string as input to ConvertXMLtoRDF:
<Environment name="test"><hasLatitudeDegrees>50</hasLatitudeDegrees></
Environment>
....and...
<Environment hasLatitudeDegrees="50"></Environment>
I'm not sure which one is correct, but neither worked. Again, my end
goal is to be able to run the following query and get back
(<Environment>, 50).
SELECT ?subject ?val
WHERE {
?subject a :Environment .
?subject :hasLatitudeDegrees ?val .
}
Currently, when I use either of the 2 xml strings above as input to
ConvertXMLtoRDF, a (<Environment hasLatitudeDegrees="50">, rdf:type,
Environment) triple is properly created. I believe this is because I
added sxml:element="Environment" to the annotations of my Environment
class.
My problem is that I cannot seem to create the hasLatitudeDegrees
triple as a type :hasLatitudeDegrees. I also cannot get the importer
to create the association of the new Environment with the new
hasLatitudeDegrees instance.
Where exactly do I need to add sxml:element or sxml:attribute
annotations? The Environment class? hasLatitudeDegrees
datatypeProperty? What should their values be? Strings? Or class
references? (I have added sxml:element and sxml:attribute to the
Environment and hasLatitudeDegrees property, and tried every possible
combination of moving them around as well).
How do I get the importer to use hasLatitudeDegrees as a predicate
instead of a subject or object? Currenlty, the Environment and
hasLatitudeDegrees triples are related by a composite:child
predicate.
If there is an example of this anywhere, I would greatly appreciate
it. The documentation was helpful, but it did not explain how to
create a parent class with a child relation containing a give value.
Thanks,
Kevin
