Is it possible to specify global variables for a transformation file?
For example static strings which can be used for identifiers.
And are there some good sources where I can read about QVTO?

best regards,
Gilbert

Global variables for the transformation can be defined using 'property'
keyword as follows:

modeltype ecore uses "http://www.eclipse.org/emf/2002/Ecore";
transformation MyTransformation();

property moduleProp : String = '';

main() {
var v := moduleProp;
}

QVTo supports configuration and intermediate properties as well. For
example:

configuration property cfgProp : String;
intermediate property EPackage::myFriend : String;

There's some documentation about QVTo available in the "Documentation"
section: http://eclipse.org/m2m/qvto/doc/
Our wiki page gives a reference to the official QVT spec from OMG
http://wiki.eclipse.org/M2M/Operational_QVT_Language_(QVTO)
