Hi all, I'm trying to use SPIN (which I'm quite impressed by, love to reuse my SPARQL knowledge); I've had some success but run into a situation in which the rule runs for a long time then results in Java out of heap space.
The SPARQL query that I'm using executes quickly directly, but not when run via SPIN. I'm trying to understand why. The code and data are on github: https://github.com/jameshowison/softcite/tree/spin-issue The relevant code running the rules is: https://github.com/jameshowison/softcite/blob/spin-issue/code/src/main/java/edu/utexas/ischool/jhowison/TTLRepository.java#L257-L280 The relevant SPIN rule is: https://github.com/jameshowison/softcite/blob/spin-issue/data/SPINrules.ttl#L56-L68 bioj:selection a rdfs:Class ; spin:rule [ rdf:type sp:Construct ; sp:text """ # Moves all codes directly onto DirectSelection, even if they originated # on a reference. CONSTRUCT { ?this ca:isTargetOf [ ca:appliesCode ?coding ] . } WHERE { ?this bioj:has_reference ?ref . ?ref ca:isTargetOf [ ca:appliesCode ?coding ] . }""" ] ; This should get things working locally for anyone kind enough to take a look for me, dependencies via Maven. You'll have to edit the path variable at: https://github.com/jameshowison/softcite/blob/spin-issue/code/src/main/java/edu/utexas/ischool/jhowison/TTLRepository.java#L37 git clone https://github.com/jameshowison/softcite.git cd softcite/code mvn -Dtest=AppTest#testSPINoutput test (or mvn test) I've tried it with spin:thisUnbound "true"^^xsd:boolean ; as well, but no cigar. Is there something recursive going on here that I can control?
