Hello!

I just finished the beginner's tutorial and created the Mindmap Modellin=
g =

Tool.
Everything works fine.

However, I have a question concerning the ecore-Meta-Model =

( http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.gmf/exa mples/org.e=
clipse.gmf.examples.mindmap/model/mindmap.ecore?root=3DTechn ology_Projec=
t&view=3Dmarkup&content-type=3Dtext%2Fvnd.viewcvs-ma rkup&revision=3DHEAD=
).

The Meta-Model uses Annotations to extend the MetaData. What purpose do =
=

these annotations have? Is there any documentation on how to use these =

specific annotations?

Thanks

Rainer

Rainer,

Have a look at:

XML Schema to Ecore Mapping
< http://www.eclipse.org/modeling/emf/docs/overviews/XMLSchema ToEcoreMapping.pdf>

These annotations will direct the serialization of the instance to
respect the original schema (or to serialize the way the annotation
specifies since you can add these manually to any model).
