problems with ETL [message #584287]

I turn him to writing because I have some problems programming the rules in ETL.
I have some doubts.

The first one is that in the file "UML.model" I do not know like to accede to the elements that are inside the package "uml".
Since I accede to the element that this inside the package uml???

The second problem is that the rules that they declare in ATL since " unique lazy rule " declare themselves in ETL as "operation"??

The third problem is that I have v.Model:=package(); And on having assigned value to the variable 'model' me the mistake appears

"Property 'Model' not found in object PrimitiveType [Name=CHAR]"

Thank !!!

Not sure I understand this. Could you please elaborate?

parameter-less operations annotated with @cached (so that they are
executed only once) is probably the way to go

I've looked at the metamodel and I think it should be v.model instead of
v.Model
