Hello! I cannot find in any ATL-Sample how must the ATL-rule look like, if I have 2 classes on the Left side and 1 class on the right side?

Here is the description to this transformation:

http://pics.livejournal.com/modeller77/pic/00001z00/s640x480

On the left side we have specobject and spectype (input modell) and on the right side - the Class Attribute (output modell).

Could please someone help me to right the ATL-rule for that transformation?
Thanks.

Alexey

You can have multiple "from" elements :

from s : MM!A , t : MM!B

Or, better, like this:

rule SpecGroup2Artefact {
	
	from
	   s: RIF!SPECGROUP
	to
	   t: ISyFMU!ARTIFACT ( 
	      identifier<-s.IDENTIFIER, name <- s.LONGNAME	
	   )
}

From your initial question, it would be :

rule Spec2Attribute {
from
so : IN!specobject,
sp: IN!spectype
to
attr : OUT!Attribute(
... )
}
