All,
I'm trying to define this one simple rule using the Jess Tab in Protege 3.4.3:
(defrule duplicate_requirement
"This rule will search by requirement name to find duplicates"
?softwareRequirement1 <-
(object {is-a ==
http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirement})
?softwareRequirement2 <-
(object {is-a ==
http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirement
&& http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirementName ==
?softwareRequirement1.http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirementName})
=>(printout t "Found Duplicate Requirements"
?person1.http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirementName
crlf))
Jess returns this error:
Message: Can't use infix expressions with multislots at token
http://pluto.cse.msstate.edu/rae20/SRSontology#SoftwareRequirementName.
I'm simply trying to compare two object facts of a 'is-a' type and seeing if
the RequirementName slots are identical. Thanks for the help.
