log:equalTo was wrong assumption, should have been owl:sameAs

query http://www.agfa.com/w3c/euler/example003Q.rq is now running

given a background graph which is the merge of
http://lists.w3.org/Archives/Public/public-cwm-talk/2005JulSep/att-0021/example001P.n3
http://lists.w3.org/Archives/Public/public-cwm-talk/2005JulSep/att-0021/example002P.n3
and  the rdf plus owl inferencing with

the answer is

Hi, Dan

We do expect to have partial SPARQL implementation in euler soon
including lots of OWL
will mainly be something like


PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX log: <http://www.w3.org/2000/10/swap/log#>
PREFIX rpo: <http://eulersharp.sourceforge.net/2003/03swap/rpo-rules#>
PREFIX : <case001#>

CONSTRUCT
  {?P rpo:mu ?X}

WHERE {
  {?P rpo:mu ((:ChildAge :IncreasedIntraocularPressure)^owl:intersectionOf 
?M).
   ?X log:equalTo ((:ChildAge 
:IncreasedIntraocularPressure)^owl:intersectionOf ?M)}
  UNION
  {?P rpo:mu ((:AdultAge :IncreasedIntraocularPressure)^owl:unionOf ?M).
   ?X log:equalTo ((:AdultAge :IncreasedIntraocularPressure)^owl:unionOf 
?M)}
  UNION
  {?P rpo:mu (:IncreasedIntraocularPressure^owl:complementOf ?M).
   ?X log:equalTo (:IncreasedIntraocularPressure^owl:complementOf ?M)}
  UNION
  {?P rpo:mu ((:AdultAge 
:NormalIntraocularPressure^owl:complementOf)^owl:intersectionOf ?M).
   ?X log:equalTo ((:AdultAge 
:NormalIntraocularPressure^owl:complementOf)^owl:intersectionOf ?M)}
}

Hmm.. the ^ might be too much N3..


We now do this in N3QL


@prefix owl: <http://www.w3.org/2002/07/owl#>. 
@prefix q: <http://www.w3.org/2004/ql#>.
@prefix rpo: <http://eulersharp.sourceforge.net/2003/03swap/rpo-rules#>.
@prefix : <case001#>.

[]
q:select {?P rpo:mu ((:ChildAge 
:IncreasedIntraocularPressure)^owl:intersectionOf ?M)};
q:where  {?P rpo:mu ((:ChildAge 
:IncreasedIntraocularPressure)^owl:intersectionOf ?M)}.

[]
q:select {?P rpo:mu ((:AdultAge :IncreasedIntraocularPressure)^owl:unionOf 
?M)};
q:where  {?P rpo:mu ((:AdultAge :IncreasedIntraocularPressure)^owl:unionOf 
?M)}.

[]
q:select {?P rpo:mu (:IncreasedIntraocularPressure^owl:complementOf ?M)};
q:where  {?P rpo:mu (:IncreasedIntraocularPressure^owl:complementOf ?M)}.

[]
q:select {?P rpo:mu ((:AdultAge 
:NormalIntraocularPressure^owl:complementOf)^owl:intersectionOf ?M)};
q:where  {?P rpo:mu ((:AdultAge 
:NormalIntraocularPressure^owl:complementOf)^owl:intersectionOf ?M)}.
