Hello Lorenz, I am sorry.

Can we use FACup as string rather than a resource.

Have you tried this?

You are asking something you can debug locally.

I mean it is also
possible, if allowed by rules, that we use something like this

(?x http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://
www.semanticweb.org/soccer#Team) "

 + "( ?x http://www.semanticweb.org/soccer#FACupGoals  ?goals )" +

         + " ->  (?x  http://www.semanticweb.org/soccer#FavioriteLeague

FACup, ChampLeague etc are just some plain strings.

Not having an individual FACup in your ontology is not really an
explanation for me that a property will be rendered as annotation
property in Protege after rule execution and storing the data with Jena.

I want to ask Lorenz, about the Then part of the rule:

THEN    -> team FavoriteLeague is FACup

FACup is the resource in my owl (just followed Create Instance tab in
Protege and Protege has give it the default URI like other resources in

Before we execute the rule, is it must that we should declare it in Java
code like we do in Jena class before using it in Rules like
OntClass team = model.getOntClass(ns + "Team")

Because I am sure the problem lies in the resource FACup (or its URI).

I don't understand your problem now, sorry. It's too confusing.

You said that you changed the whole ontology: upload it somewhere such
that we can see it

Show the final rule that doesn't work, not in pseudo-syntax but how you
use it in Jena.

Upload the code somewhere

I am sorry for any inconvenience I have created. I really dont know how
create minimal code snippet or uses Github.

Coming to the problem, what I noticed is the problem is in the object
FACup here.
team1  FavoriteLeague  FACup

Because I made changes and coming to the down, used different
(in place of  FavoriteLeague), and made the rule simple to:
If x is a Team, then x FavoriteLeague is FACup ,
If x is a Team, then x Wins is FACup etc just for simplicity.

In a nutshell, changed everything except object of rule FACup and it
appears in Annotation area so the problem for sure is in the URI of
Now about resources FACup, PremierLeague, ChampionsLeague, these are
associated with anything in the ontology (neither Types of anything,
data/object assertions), rather I just created it in Protege with URI
other resources.
URI of Team Class: http://www.semanticweb.org/soccer#Team
URI of FavoriteCategory : http://www.semanticweb.org/
and URI of FACup: http://www.semanticweb.org/soccer#FACup

So I dont know if it is mandatory to get the value of resource
http://www.semanticweb.org/soccer#FACup first before the rules
because simple putting it in the rules not working for me.

Sorry once again.

in your last answer you wrote

*String ns="http://www.semanticweb.org/soccer

if you provide us no information and the information that you provide
of such poor quality, then it's not possible to help you.

Last time that I'll write this here:

1. provide the WHOLE ontology (there are many services only where you
can put your file online for free)
2. show the minimal code snippet that makes it possible to see that it
doesn't work

Or put everything into a Github project

Hi Lorenz, the ns is wrong, how?

String ns="http://www.semanticweb.org/soccer#


(?x http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://
www.semanticweb.org/soccer#Team) "

Hello Lorenz, I am sure I have used the FavoriteLeague as Data

I have changed the spelling of FavoriteLeague. to FavoLeague,
but every time the same disappointing result.
My namespace is also same in whole program:

*String ns="http://www.semanticweb.org/soccer
Ehm that's a totally wrong namespace declaration. To be honest, I
understand why you don't see this...and the namespace in the rule is
obviously NOT the same then
favleague is declared as:

 *OntProperty favleague=model.getOntProperty(ns+
Please tell me, what do you think is the concatenation of the String
the variable ns and the String "FavoriteLeague" ?

//All my data properties are declared like this and it works.  For

Gives the result but in Annotation area of Protege

COMPLETE MINIMAL EXAMPLE, please. You have so many
errors & omissions in the code you show us we can't
tell which one is the one you're asking about.

If Protege is putting things in the annotation area
I'd guess that means the thing isn't declared as either
a DataProperty or an ObjectProperty. Given your erratic
spelling that's quite likely.
