ATL beginner question [message #88396]

Hi,
I am new to ATL and I am trying my first very simple transformation. I
have a metamodel called processmap.ecore having EClass Map and an
attributeof the Map - title. I want to map the Map.title to an UML
Package.name. My code is the following
rule MapToPackage {

from m : processmap!Map

to p : UML!Package (
name <- m.title
)
}

But I get a strange error on the line from m : processmap!Map namely
mismatched input 'Map' expecting NAME
Why is it not accepting the Map element? What kind of Name is being
expected ...
Thank you for the answer
Petko

Hi,
Map is a keyword in ATL. Like Sequence, Set, etc.
You can escape keywords using quotes: processmap!"Map"

kind regards,

Alfons
