| Generating ecore file from various sources [message #405657] |

Hi,
The EMF generator model (genmodel) can be initialised from several
kinds of sources, including ecore files, Java interfaces and XML
schemas. The standard wizards supports selecting either of these,
before building the genmodel file. In my project I work with dynamic
EMF models and instances, so I cannot rely on the generator. But I
would still want to support e.g. XML schemas, in addition to the
native ecore files. Is it possible to convert the above mentioned
files directly to ecore (or rather, an in-memory EMF model), without
involving the generator? I have seen an example using XSDEcoreBuilder,
which builds a set of EPackages, but what I'm looking for is a more
generic approach. I've tried to understand the importer extension
point, but AFAIU this is tied to the generator.

Yes, this is my source of information about XSDEcoreBuilder. I agree
it is generic and handles XML sources well.

Aha.

You're right that I was confused. I found slides from EclipseCon 2006,
that explained the importer/exporter mechanism, which is (almost) what
I want. I now better understand the role of GenModel and its use
outside the context of the Generator. I was hoping for a slightly
simpler and leaner mechanism, perhaps at a layer beneath the
importer/exporter, but I accept that this isn't feasible.
