Customizing saving Model to XMI via XMISaveImpl options [message #986938]

Is there any possibility to extract model to XMI file with the following option:

<root>
...
  <box xmi:type="mymodel:Box" xmi:id="_123wefwefwjefgeg" name="GreatBox">
    <title>_k84xEzSoEeKTvczlP0YbOQ</title>
  </box>
</root>
...
<title xmi:id="_k84xEzSoEeKTvczlP0YbOQ" name="SomeTitle" elementType="NORMAL"/>

Instead of the following:

<root>
...
  <box xmi:type="mymodel:Box" xmi:id="_123wefwefwjefgeg" name="GreatBox" title="_k84xEzSoEeKTvczlP0YbOQ"/>
</root>
...
<title xmi:id="_k84xEzSoEeKTvczlP0YbOQ" name="SomeTitle" elementType="NORMAL"/>

I tried to play with Containment option of Box.title attr in Ecore model, but it seem's that I need to extends XMISaveImpl and change smth there.

Hi,

Add an annotation to your Box::title attribute in the Ecore model as follows:

source: http:///org/eclipse/emf/ecore/util/ExtendedMetaData
detail: kind -> element

Cheers,

Christian

Hi,

Can you be more specific?
Smth like this:

http://habrastorage.org/storage2/171/efe/84c/171efe84cee2616ede4ea4c2a0633c72.png

Here, some Base class comprises semanticElement:SemanticElement attribute to which I added annotation.

Alexander,

Create an EAnnotation on the "title" EReference in your Ecore model as
Christian outlined and use XMLResource.OPTION_EXTENDED_METADATA mapped
to Boolean.TRUE in your save options map (or set save options in your
resource factory where you create your resource).

Hi Ed,

I don't understand how to do that:
1. I added new child to "title" -> Eannotation
2. In the "Properties" view of "title" attr, we have only two properties:
- References: I set it's value to "title:Title"
- Source: I set it's value to http:///org/eclipse/emf/ecore/util/ExtendedMetaData

After reloading genmodel and regenerating Model Code nothing changes.

Don't do that.

Yes.

And then create a "Details Entry" under the EAnnotation to hold the
key-value pair.

How do you detect changes? I'd expect the generate XyzPackageImpl to
change because of the annotation, but it's easy not to notice that. That
information is used by the serializer when you direct it to look at such
annotations via that save option.

That works perfectly.
