Hi.
I am working on Birt/EMF integration, and I try to get the
ECore/XSD roundtrip working for this schema (see attachment)The
((design.xsd is located in the BIRT source code in the
org.eclipse.birt.report.model project in the
src\org\eclipse\birt\report\model\parser\design.xsd file. ))
I create an EMF genmodel from the schema, and then I reexport it to XSD,
and try to get structurally the same. I intend to post problems here,
until they are all resolved or covered by feature/bugs ;-)
Here the first: (ORIGINAL is what Birt uses, ROUNDTRIP is the outcome
after we went through EMF roundtrip):
Root element
------------
ORIGINAL
--------
<xs:schema
targetNamespace="http://www.eclipse.org/birt/2005/design"
xmlns="http://www.eclipse.org/birt/2005/design"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
ROUNDTRIP
---------
<xsd:schema
targetNamespace="http://www.eclipse.org/birt/2005/design"
xmlns:design="http://www.eclipse.org/birt/2005/design"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
ecore:nsPrefix="design"
ecore:package="com.jaree.birt.design">
Here my questions:
1) how can I achieve, that the original definition:
xmlns="http://www.eclipse.org/birt/2005/design"
is generated rather than
xmlns:design="http://www.eclipse.org/birt/2005/design"
2)Why are the options
elementFormDefault="qualified"
attributeFormDefault="unqualified"
not in the generated schema?
3) Is there a way to avoid the generation of the ecore options and
namespace? I mean they where not needed at the beginning, so why having
them here?
It is very unlikely that a huge project like Birt can move their
code to EMF, but if the ECore-XSD roundtrip works properly, we do not
need to care. As well this is the entry into the MS world. I'd like
to repeat this experiment with the openoffice schema, and later
with some MS schemas.
Best, Philipp

Philipp,
I make no guarantee that XSD -> Ecore -> XSD is a round trip. I've
tried to ensure that Ecore -> XSD -> Ecore is a round trip and hence the
annotations to preserve details that aren't otherwise going to round
trip properly. More comments below.

Since you already have a .xsd, it seems not particularly useful to try
to regenerate it...

Things like the prefix used for the schema for schema namespace or
prefix for the target namespace are syntactic sugar that have no
semantic significance. Don't expect them to be preserved. Information
like the qualified namespace you used "com.jaree.birt.design" and the
nsPrefix won't be preserved without the annotations.

EMF won't generate this style for you unless you specialized the schema
builder to do that.

EMF only records the actual namespace on the elements and the attribute
and has no idea if they are the way they are because it's a local
element verses a global element or whether form="qualified" verses
elementFormDefault="qualified" is used. So this won't round trip
either. But the actual namespace for each element and attribute should
still be correct.

For roundtripping Ecore-> XSD -> Ecore they are needed. Again, you'd
need to specialize the build or post process the result to achieve this
goal.

I'm not sure why it matter. You have the schema, why is there a need to
generate it?

You'll find MS loves to fill schema with their own annotations. They
are perfectly acceptable annotations after all and all conforming
processors should tolerate them.

Hi, Ed.
I understand. If XSD -> Ecore -> XSD round trip is not on your agenda,
I will not try to do it on my own...
