SWRL rule question

Support
1

Hi all,

I have a question about SWRL. I want to use the rule in Stardog.

Let consider individual A having a hasObservation object property pointing to two individuals B and C. The rule should add a property to A in case the hasValue property of B AND C meets some criteria.

Any hints?

Thanks,

Kind regards,

Why not starting with writing the rule in abstract syntax down?

hasObservation(?x, ?y), hasObservation(?x, ?z), notEquals(?y, ?z) , $THE_OTHER_CONDITIONS_HERE -> $PROPERTY_TO_ADD(?x, $VALUE_TO_ADD)

Afterwarss, you can convert into the desired rule language.

Thanks for the hint. It’s working, both in Protege as well as via the SparQL interface of Stardog.

Kind regards,
Johan,
