Hi,
thanks a lot for the helps. sorry for the vagueness of my question.
well here is a more precise example based on what I am working on.
I have the XML file below as my input file (which is an OWL file of course):
----------------------------------------------------------
<owl:Class rdf:about="urn:KAoS#ActionHistory-Property-Condition">
<owl:intersectionOf rdf:parseType="Collection">
<owl:Class rdf:about="&actions;ActionHistory"/>
<owl:Restriction
rdf:about="urn:KAoS#ActionHistory-Property-ConditionRestriction0">
<owl:onProperty>
<owl:ObjectProperty rdf:about="&behavior;performedBy"/>
</owl:onProperty>
<owl:allValuesFrom
rdf:resource="urn:KAoS#QueryAction-Property-History"/>
</owl:Restriction>
<owl:Restriction
rdf:about="urn:KAoS#ActionHistory-MinCardinalityRestriction">
<owl:onProperty
rdf:resource="http://ontology.ihmc.us/ActionHistory.owl#hasRegisteredAction"/>
<owl:minCardinality rdf:datatype="http://www.w3.org/2001/XMLSchema#int"
>1</owl:minCardinality>
</owl:Restriction>
</owl:intersectionOf>
</owl:Class>
-----------------------------------------
by applying my XSLT, the file above is converted to the XML file below
(an R2ML rule file):
<r2ml:conditions>
<r2ml:PropertyAtom r2ml:propertyID="&behavior;performedBy">
<r2ml:subject>
<r2ml:ObjectName
r2ml:objectID="&actions;ActionHistory"/>
</r2ml:subject>
<r2ml:value>
<r2ml:ObjectName
r2ml:objectID="#var:urn:KAoS#QueryAction-Property-History/>
</r2ml:value>
</r2ml:PropertyAtom>
<r2ml:PropertyAtom r2ml:propertyID="minCardinality">
<r2ml:subject>
<r2ml:ObjectName r2ml:objectID="QueryAction"/>
</r2ml:subject>
<r2ml:value>
<r2ml:TypedLiteral r2ml:lexicalValue="1"
r2ml:datatypeID="integer"/>
</r2ml:value>
</r2ml:PropertyAtom>
</r2ml:conditions>
------------------------
while parsing and generating the first part of the <R2ML> file above,
namely "r2ml:/conditions/r2ml:PropertyAtom[1]' I get to a point where
I have:
<r2ml:value>
<r2ml:ObjectName
r2ml:objectID="#var:urn:KAoS#QueryAction-Property-History"/>
</r2ml:value>
while producing
"r2ml:objectID="#var:urn:KAoS#QueryAction-Property-History" I have the
value for the attribute "r2ml:objectID" which is equal to
"#var:urn:KAoS#QueryAction-Property-History" in my generated output
file and is different from the value in the original file (in the
original file it is "urn:KAoS#QueryAction-Property-History").
ok at this point and after generating the value of "r2ml:objectID", I
need to generate another <r2ml:property> element, having the value of
"r2ml:objectID" embedded in its definition, but as a child of
<r2ml:conditions>. so the final output should be like:
<r2ml:conditions>
<r2ml:PropertyAtom r2ml:propertyID="&rdf;type">
<r2ml:subject>
<r2ml:ObjectName
r2ml:objectID="#var:urn:KAoS#QueryAction-Property-History/"/>
</r2ml:subject>
<r2ml:value>
<r2ml:ObjectName r2ml:objectID="John_Smith"/>
</r2ml:value>
</r2ml:PropertyAtom>
<r2ml:PropertyAtom r2ml:propertyID="&behavior;performedBy">
<r2ml:subject>
<r2ml:ObjectName
r2ml:objectID="&actions;ActionHistory"/>
</r2ml:subject>
<r2ml:value>
<r2ml:ObjectName
r2ml:objectID="#var:urn:KAoS#QueryAction-Property-History/>
</r2ml:value>
</r2ml:PropertyAtom>
<r2ml:PropertyAtom r2ml:propertyID="minCardinality">
<r2ml:subject>
<r2ml:ObjectName r2ml:objectID="QueryAction"/>
</r2ml:subject>
<r2ml:value>
<r2ml:TypedLiteral r2ml:lexicalValue="1"
r2ml:datatypeID="integer"/>
</r2ml:value>
</r2ml:PropertyAtom>
</r2ml:conditions>
to fully understand it you need to have a background on KAoS policy
language and also R2ML (a rule interchange fomat), besides OWL. in my
former question I had tried to make it simpler which had resulted in
the vagueness you noticed. But regardless of the semantics of the
languages and considering the XML-based format of all of them, I hope
you could get my question.
thanks a lot for your great help and looking forward to hearing your
kind suggestions,
cheers,
