Michel; using SPIN to generate this inference is very straightforward.  Create a SPIN file and make sure inferencing is configured to use TopSPIN.

Create your model, per below and in the class X, property spin:rule, add this rule:
CONSTRUCT {
    ?this a unnamed:XSmall .
}
WHERE {
    ?this unnamed:length ?length .
    FILTER (?length < 10) .
}

Run inferences and you will get the classification that is specified by the rule.

Hi Holger

 

Ok, thx. Could you give me a hint on how to do this with SPIN or would it really require an extension of spin itself?

Guess it a kind of global spin rule you would attach to “any individual” iso to a class?

Subject: Re: [topbraid-users] automatic classification?

 

I don't think any of the built-in reasoners of TopBraid understand custom datatypes. It should be a doable extension to the SPIN OWL RL model, similar how spinowl.ttl already supports constraint checking on such user-defined datatypes.

Suppose i have a class X and subclass XSmall

And property length

 

I define for XSmall an equivalentclass: (X and  (length only xsd:float[< "10"^^xsd:float]))

 

 

I now have an instance of X being x with value 5 for length

 

What reasoner do I have to run to infer: x rdf:type XSmall?

 

Or am I doing something wrong in principle….

 

(swiftowlim is in my scenario…)

 

Thx michel
