Thanks for letting us know about this work.

I see some details that are probably not as
you intended:

 xmlns:owl="http://www.w3.org/??/owl#"

Try

 xmlns:owl="http://www.w3.org/2002/07/owl#"

per http://www.w3.org/TR/owl-ref/#owl-uri-namespace

Also, where you write

	<owl:Class rdf:about="file:/C:/Aingeru/OperOnt/actors#Actor">

I think you mean

	<owl:Class
rdf:about="http://siul02.si.ehu.es/Aingeru/OperOnt.owl#Actor">

You might try some of the syntax checking tools from
our implementation report
  http://www.w3.org/2001/sw/WebOnt/impls#Implementations
for example
  http://phoebus.cs.man.ac.uk:9999/OWL/Validator

which reports problems such as

 [line=134:column=-1] URI
'file:/C:/Aingeru/OperOnt/actors#ConditionChecker Agent' cannot be
resolved against curent base URI
http://siul02.si.ehu.es/Aingeru/OperOnt.owl
