Hi,
Can you please tell me in detail how you have implemented
the xsd schema import/export. What all metamodels and api
have been used.
How the whole code/process flows .

thanks

Gitanjali,

If you set breakpoints in XSDEcoreBuilder and EcoreSchemaBuilder and
watch the behavior of creating an EMF project for an XSD and exporting a
GenModel to XML Schema, you can get a very good idea what's involved and
then if you have more specific questions, I can answer those.

hi,
we have made our own modeling framework using/extending your
api's. Now we have implemeted cmof export and import. I
want to know that how can i create an xsd schema for it.
Do i need to create an XSD META MODEL for it and how
the whole flow will be.

Gitanjali,

There already is an XSD meta model, i.e., XSD.ecore exists and the XSD
plugin implements it. So XSDEcoreBuilder and EcoreSchemaBuilder map any
*.ecore instance from and to an *.xsd instance. So I imagine if you
have CMOF <->Ecore and Ecore <-> XSD already exists that by transitivity
you already have your mapping and don't need anything else...

Hi Ed,
we have our own modeling framework with our own meta meta,
meta models. Using the eclipse parser and its api we created
import and export of cmof/emof xml file(xmi).Now what changes
will be required in the existing code/project so that on
clicking export the meta/user models xml schema/xsd
should be generated.
Because in cmof export what we did was:
take our meta model then create and instance of cmof meta model
in that instance model the meta model was copied.
the instance model was then transformed into cmof xmi so that it maps to
all
the tags like <ownedmember>, <memberEnd> etc.
Is it possible to make some changes in
the existing code or the implemetation for xsd schema is
totally different from this.

That's a lot of metas. Does it make your brain hurt? :-P

Not sure what you mean by "the eclipse parser". I suppose you means
org.eclipse.emf.ecore.xmi's ability to read and write .xmi files for
which *.ecore models exist.

Clicking it where? In the Generator when working with a GenModel?

I'm lost in meta space.

Even further lost in the metaness of it all...

Wow. I could cry now.

I am crying now...

I no longer have any idea what "this" really is. I'm scared to ask you
to explain further.
