Jena rules
Hello I have Employee ontology where different employees have different
positions and tasks. Some are in technical positions performing technical
tasks and have low salaries. Some are on managerial posts and have huge
salaries.
I will add salaries dynamically using Jena for each employee using Property
and value.
Select * where { emp:employee emp:hasTask ?task} It will display all
employees tasks i-e both technical and managerial.
I need Jena rules in which we can say: emp:employee emp:hasSalary greater
than $4,000, the query returns only managerial tasks and technical tasks
hides from her.
Thanks for understanding my problem. If some one needs more explanation, I
can provide.
regards

And what kind of rule have you tried so far? I mean, at least some
starting point would be good. Nobody here will do the work for you. And
please share th eontology, or at least some sample data as Paul already
said.

Do you really need to use rules or would you be OK with just changing the
query a little?
Also, do you have a sample of the data you are using?
