Hi everyone,
  I do appreciate your help.
I am using JessTab to run rules,I have written a rule to change the value(string) of an instance :
(defrule Rule-1 ?obj1 <-(object (is-a Customer) (is-a-name "Customer") (:NAME "Customer_Inst") (hasState "Ready" )) => (slot-set ?obj1 hasState "waiting")) 

But now I want to introduce (Ready, Waiting) as intsances of class "State".I have done it and now I have two instances Ready and Waiting . Also I have defined "hasState" as a slot of type of State. 
But now I wonder how can I write  similar rule (as above) to change the relation between Customer and Ready to a relation between Customer and Waiting?

Hello everybody!

I would like to know if there is some way that I can to export the Owl restrictions to Jess. In my ontology I can't.  

Thanks!
Priscilla.

I am a newbie, but it is my understanding that SWRL can only assign a  
value to a property that is not yet valued. Allowing properties to be  
changed might invalidate previous inferences.

Does your rule perhaps add a second hasState property to the Customer  
rather than changing the existing value?

You are right - in SWRL this would not be valid. However, I think he is 
using the JessTab (not the SWRLJessTab), which is not as formally 
constrained (or as safe) as SWRL.

Are you referring to the JessTab or the SWRLJessTab subcomponent of the 
SWRLTab? The SWRLTab does not support most OWL restrictions at the 
moment:

Hi Martin!

I'm using the SWRLJessTab in the Prot?g? 3.3 beta (where shows the subtab 
"Restrictions" but don't works).
How can I to write the restrictions in the Jess directly? Are they must be 
rules? Do you have any example?
Because I wrote the rules only, example:

OneWayDelay(?x)  ?  OneWayTool(?y)  ?  VoIP(?z)  ?  isMeasuredBy(?x, ?y)  ? 
requires(?z, ?x) ? needs(?z, ?y)

In this case, the property isMeasuredBy has restrictions. Some values to x 
only can be acceptable to other some values ?y. Where can I say this?

Thank you so much!
Priscilla.

?obj1 <- (object ...) gives you a binding to a fact, not the object. You 
need to match (OBJECT ?obj1) as part of the pattern.

Assuming that you have a Jess function (isState ?state ?stateName) that 
determines whether an individual ?state is a state with ?stateName 
(e.g., "Ready"), and a function (getState ?stateName) that returns a 
state individual with name ?stateName, you can write your rule as

(defrule Rule-1
   (object (is-a Customer) (is-a-name "Customer")
           (:NAME "Customer_Inst") (OBJECT ?obj1)
           (hasState ?state&:(isState ?state "Ready")))
   => (slot-set ?obj1 hasState (getState "Waiting")))
