Higher order transformation [message #1062391] Fri, 07 June 2013 10:00 Go to next message

Hi,
I have several metamodels imported from XML schemas. I would like to use XML extractor to save models conforming to those metamodels to XML files.
But I do not want to define a transformation for each of the metamodels. The rules to transform to XML metamodel are actually all the same and are based on information in the metamodels.
Is it possible to create a single transformation that would do that. Something like:

create OUT : XML from METAIN : ECORE, IN : METAIN;
...


Thanks,
Michal

Hello,

If your metamodel (in Ecore) has been directly created from an XML schema, then EMF itself is already able to import corresponding XML documents as models and to export back such models as XML documents.
You should take a look to the EMF documentation to get more info about this.

The problem really is I could not find any way to automate loading/saving instance documents (eg. an ant task).

Hello,

You could do this via Java code to automate the full process/chain.
