Hi,
I've make transformations with ATL and I've a problem.
My target metamodel is made of
two classes EVENT and PORT which inherit from a class NODE,
three classes ROOT,LEAF and INTERMEDIATE which inherit from EVENT.
Name attribute of classes is declared in NODE and other attributes
in EVENT, PORT, LEAF etc.
Now, when I write a rule, attributes of subclasses are not seen
in the model target.
How can I to visualize it?
Thanks
Luciana

Hello,
thanks for you help.
Here there are the rules and the final model.
RULE
entrypoint rule FaultTree () {
to
ft : FT!FaultTreeModel (
description <- 'Case Study',
name <- 'Fault Tree'
)
do {
thisModule.Model <- ft;
for ( e in thisModule.allClasses) {
ft.node <- thisModule.cActor(e);
}
}
}
lazy rule cActor {
from
a : UML!Actor
(not a.useCase.isEmpty())
to
r : FT!Root (
name <- a.name,
description <- 'Vogliamo stimare la Reliability del sistema',
SystemReliability <- ' '
)
do {
r.port <- thisModule.createPort(a);
}
}
lazy rule createPort {
from
b : UML!Actor
(not b.useCase.isEmpty())
to
p : FT!Port (
name <- 'Port of ' + b.name,
type <- #typePort,
outdegree <- '1'
)
do {
(*) p.event <- thisModule.uc2Intermediate(b);
}
}
MODEL TARGET
<?xml version="1.0" encoding="ISO-8859-1"?>
<FaultTreeModel xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="C:\eclipse2\workspace\UML2FTA\Metamodels\" description="Case Study"
name="Fault Tree">
<node xsi:type="Root" name="System" description="Vogliamo stimare la
Reliability del sistema">
<port name="Port of System"/>
</node>
</FaultTreeModel>
I've another problem is that instuction (*) is not performed.
Perhaps I have planned badly the transformations,
with this rule I try build a model that represent a tree made of Port and
Event.
It is first time that I make transformations,
if you are some suggestion about it, these are well welcomed.
Thank you very much for all.

Hi William,
thank you very very match about your suggestion.
I try to rewrite my transformation in a simplier form, but
my metamodel is empty and I have some errors.
Here it's all.
How can I do?
Excuse if I ask you too questions, but it is very important for me.
RULE
rule FaultTree {
from
model : UML!Model
to
ft : FT!FaultTreeModel(
description <- 'Case Study',
name <- 'Fault Tree',
node <- thisModule.cActor(model)
)
}
rule cActor {
from
a : UML!Actor
(not a.useCase.isEmpty())
to
r : FT!Root (
name <- a.name,
description <- 'Vogliamo stimare la Reliability del sistema',
SystemReliability <- '',
port <- createPort
),
createPort : FT!Port (
name <- 'Port of ' + a.name,
type <- #"or",
outdegree <- '1',
parent <- thisModule.uc2intermediate(a)
)
}
rule uc2Intermediate {
from
uc : UML!PAstep
(not uc.subject.isEmpty)
to
intermediate : FT!Intermediate (
name <- 'Reliability '+ uc.name,
composedProbability <- ' ',
port <- thisModule.useCase2Port(uc)
)
}
rule useCase2Port {
from
uc : UML!PAstep
to
porta : FT!Port (
type <- #"and",
outdegree <- 1,
name <- 'Porta'+ uc.name,
event <- Sequence { leaf, intermediate }
),
leaf : FT!Leaf (
name <- 'Evento in cui viene richiesto lo scenario '+ uc.name
basicProbability <- uc.probability
),
intermediate : FT!Intermediate(
name <- 'Reliability di tutte le operazion nello scenario ' +
uc.name,
composedProbability <- ' ',
port <- thisModule.intermediatePort(intermediate)
)
}
rule intermediatePort {
from
uc : UML!PAstep
to
port : FT!Port (
type <- #"and",
outdegree <- '1'
)
}
