Hi
What is the proper way to use Jena rules in our application(s) ?
(1) Inside code (Eclipse, etc)
(2) using some text file and then imports it.
In second case, what will be then the order of rules execution?
Thanks - the current snapshot works fine!
Cheers, Joachim

Yes, recursion makes perfect sense.
Now why didn't I think of it?
Thanks Andy.

That's totally confusing and it's not clear what you're doing. SPARQL?
Using the Jena datastructures?
"fetch name of student" -> obviously the name of the RDF resource that
you assigned to "student" will be returned.
In SPARQL , given that you use UNION or VALUES, both will be returned.
But
I have student Reg.No and name property.
Reg.No Name
1 Rohit
2 Kumar
Then, if I use as: if (Reg.No==1) OR Reg.No==2
fetch name of student
In this case, which name value will be extracted from the ontology?
Rohit, kumar, or both?
Hi Nikolaos,
It is possible to call the path evaluator directly, see PathLib. You
can buld paths programmatically using PathFactory.
There is a parser for paths written in algebra syntax SSE.parsePath
(print out a few SPARQL queries with paths to get the syntax).
If you want to search
