Serializing/Deserializing ExtendedMetaData [message #507360]

Hi,

I am creating Ecore models from XML schemas using XSDEcoreBuilder. I then
place the Ecores in a registry which is used to build models from XML files
which reference the schemas. I am trying to cache the Ecores so I don't have
to keep generating them every time an XSD is referenced (I have many XSDs).
However, I noticed the ExtendedMetadata in the Ecores seems to be required
to create models from the XML files (I believe the feature lookup fails
because there is a mapping from XML names to Ecore names).

Is there a way to serialize the ExtendedMetadata with the Ecore so next time
it is deserialized the ExtendedMetadata is present? What would be the best
approach to realize this objective?

thanks
Derek

The extended meta data is driven by annotations in the Ecore model
itself so I'm not sure what you'd hope would be serialized. In fact,
I'm not sure I understand exactly the problem. You'd typically want to
keep reusing the same XSDEcoreBuilder instance if you want to keep
reusing the Ecores they generate.
