Dear colleagues
In order to test some ATL example, I defined several rules to generate
output models from input model conforming to their metamodels. The problem
is that when I define many rules in the same ATL file, only the first rule
which is executed. The others rules cannot be executed. I trying this with
many examples and I have the same problem.
Best regards,
adil

Dear collegues,
in order to describe my problem with ATL, I illustrate the Problem with an
extension of the Example provided With ATL : Author2Person. I just added
the class Diploma and the required reference to the Class Author
defined in the Author2Person example. and I added a class Qualification to
the metamodel Person.ecore:
The metamodel Author defined in the file Author.km3:
package Author {
class Author {
attribute name: String;
attribute surname: String;
reference diploms [*] : Diploma oppositeOf owner;
}
class Diploma {
attribute year: String;
attribute title : String;
reference owner : Author oppositeOf diploms;
}
}
package PrimitivesTypes {
datatype String;
}
The model which conforms to the metamodels Author.ecore ( after injecting
the Author.km3 to Author.ecore)
<?xml version="1.0" encoding="ASCII"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns="Author">
<Author name="David" surname="Touzet">
<diploms year="1999" title="PHD"/>
<diploms year="1990" title="bachelor"/>
</Author>
<Author name="Freddy" surname="Allilaire">
<diploms year="1999" title="PHD"/>
<diploms year="1990" title="bachelor"/>
<diploms year="1999" title="PHD"/>
<diploms year="1990" title="bachelor"/>
</Author>
<Author name="Kenzi" surname="Adil">
<diploms year="1999" title="PHD"/>
</Author>
</xmi:XMI>
the metamodel for Person:
the file Person.km3 is :
package Person {
class Person {
attribute name : String;
attribute lastname: String;
reference qualifications [*] : Qualification oppositeOf
owner;
}
class Qualification {
attribute qualif: String;
reference owner : Person oppositeOf qualifications;
}
}
package PrimitivesTypes {
datatype String;
}
The Program ATL that I created. I just added the Rule
diploma2Qualification to the ATL program defined for Author2Person
module Author2Person; -- Module Template
create OUT : Person from IN : Author;
rule Autho2person {
from a: Author!Author
to
p: Person!Person (
name <- a.name,
lastname<-a.surname
)
}
rule diploma2Qualification {
from diplom :Author!Diploma
to
Q : Person!Qualification(
qualif<-diplom.title
)
}
After running this atl program, I have as a result the follow model :
<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns="Person">
<Person name="Kenzi" lastname="Adil"/>
<Person name="David" lastname="Touzet"/>
<Person name="Freddy" lastname="Allilaire"/>
</xmi:XMI>
As we can see the second rules defined in the atl program is not executed.
The information about Qualification doesnt exist in the result model.
The Question is How to identify the Problem? Is a model problem? Why the
second rule is not executed?
Best regards,
Adil

Hi adil,
I think that the problem comes on the second rule called
'diploma2Qualification '
you can try with this:
rule diploma2Qualification {
from diplom :Author!Diploma
to Q : Person!Qualification(
qualif<-diplom.title ,
owner <- diplom .owner
)
}

Dear Adil,
Thank you very much for your feedback. I modified the second rule as you
suggested( I added the owner <-diplom.owner to the second rule ), however
the probelem can't be resolved. I can't run the second rule.
best regards,
