Hi again Dave, sorry if I have not explained appropriately,
let me tell you at first my goal: I am inspecting a dataset of 1,5 millions individuals, againts another dataset with 5k *search_ID *values, where I have to get an individual with a given value in a property. I use rule 2 with search_ID in *registration_Authority_entity_ID* property, in order to identify individuals with search_ID value. I think rule 2 could be rewritten as follows: rule 2= (?b rdf_ns:type Entity) (?b registration_Authority_entity_ID " *search_ID'*) -> (?b has_ord ?ord) rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns"; rdf_ns = rdf+"#" In my experience with owl api, when a rule is triggered, no change occurred in the original data, that means rule does not affect original model, and an inferred model is generated, and this model can be store separated. When I trigger rule 2, I obtained this inferred model, and when I inspect it, I can see the individual with the property value, but wrong, in the same way, when I execute rule 1, I do not obtain any result, and model holds blank. I code the necessary control element to verify that inferred model of rule 1 holds blank, in other words I confirm that there is not triggering. Currently I am executing the following rule: rule_3 = (?b rdf_ns:type Entity) (?b registration_Authority_entity_ID *search_ID*) -> (?b rdf_ns:type Entity) So, I obtain all ?b individuals with value search_ID, however I require extra work to obtain the target property value, that will let me identify my individual later, and I think I should be able to get it with the rule. Hope this could clarify a little more my use case.
