Hi, sorry if I've used the wrong group for this question.
I'm looking for any working example that converts a source .tcs file into
a TCS conformant model file. I'd also be interested to know whether TCS is
good choice for converting from models to concrete text (I won't need to
go from text to model), or should I use another approach?

You could define your metamodel directly in KM3 (which is a Domain
Specific Language or DSL for defining metamodels) and then automatically
transform it into other formats such as Ecore for example.

I think the error comes from the value of the "metamodel" parameter of
the am3.loadModel task. For instance, it may be metamodel="AddressBook"
if you already have loaded the AddressBook metamodel like this:
<am3.loadModel modelHandler="EMF" name="AddressBook" metamodel="MOF"
path="AddressBook.ecore" />

The normal process is to create first your metamodel ;-)

In this case (text to model), you will need to generate and to use a
"specific" AddressBook injector (i.e. AddressBook-importer.jar).
I have created a complete TCS use case for AddressBook available here:
http://www.eclipse.org/gmt/am3/tcs/download/TCSSample.zip
And I have also started a tutorial:
http://wiki.eclipse.org/index.php/TCS/TCS_Toolkit_Tutorial
For the moment, this wiki page is only a stub. But I hope this can help
you :-)
Regards,
Freddy.
