Dear TopBraid assistance folks,
I'm new to SPIN but have recently presented how useful it could be. So now I
need to actually be able to add it to an ontology. :) Unfortunately I'm having
trouble locating documentation and moderately complex examples for SPIN. If
documentation on available functions and more complex examples exist, where can
I find this information?
Now for one of the things with which I'm having trouble. I suspect there are
multiple things wrong with my code and don't expect full debug assistance. Just
being able to add a new instance of a class to the ontology when an instance of
a different class is imported into the ontology will get me started.
I'm importing a tab delimited spreadsheet containing EventReports. For each
EventReport I want to generate an Event. I know this sounds backwards. This
isn't for real-time operations at this point. I'm essentially back filling
from a log file to test out the value of query over an ontology.
So a simpler example using the purchases.rdf file is:
I added a service report that should be associated with each service contract
through the spin:rule. I try running inferences and nothing happens.
:Report
a owl:Class ;
rdfs:label "Report"^^xsd:string ;
rdfs:subClassOf owl:Thing .
:ServiceReport
a owl:Class ;
rdfs:label "Service report"^^xsd:string ;
rdfs:subClassOf :Report .
:reportFor
a owl:ObjectProperty ;
rdfs:domain rdf:Property ;
rdfs:label "report for"^^xsd:string ;
rdfs:range :Report .
:ServiceContract
a owl:Class ;
rdfs:subClassOf :Purchase ;
spin:rule
[ a sp:Construct ;
sp:templates ([ sp:object :ServiceReport ;
sp:predicate rdf:type ;
sp:subject
[ sp:varName "report"^^xsd:string
]
] [ sp:object spin:_this ;
sp:predicate :reportFor ;
sp:subject
[ sp:varName "report"^^xsd:string
]
]) ;
sp:where ([ sp:object :ServiceContract ;
sp:predicate rdf:type ;
sp:subject spin:_this
])
] .
Best regards,
Michelle
