Hello,


Some comments about your issues:

1.

AMW is a workbench that supports generic mapping management. The workbench is stable. It 
can be extended to be used for different mapping tasks, for instance to map between DSLs 
and UML profiles.

In the DSL2Profile use case, we develop a weaving model which is a mapping between a UML 
profile and a DSL for MOF.

This mapping table is equivalent to the situation illustrated in your figure in the 
"Connecting DSL-eCore w/ UML2" post. This means AMW could be used to develop such mappings.

2.

In this use case we do not handle possible data loss issues. One possibility would be to 
create an auxiliary model that is generated in the same time you transform a Profile into 
a DSL. The transformation that translates the model back should handle this auxiliary 
model as well.

3.

If I understood well, the event-based approach means that when you modify one element in 
the UML model, the equivalent element is automatically updated in the DSL, right?
The transformations are typically developed to translate a whole input model into a whole 
output model. So, even if you have an event that triggers one transformation, it would 
regenerate the output model entirely.
An alternative would be to create a weaving model with the mapping links and to create a 
component that interprets these links (and that does the event-based modifications).


Regards,

Marcos.
