Hello all,

I created an .odesign project and I am able to create new items that I need. Now, I would like to extract some subparts of the model to a new XML file. For example, my model is just like below:
<?xml version:"1.0" encoding="UTF-8"?>
<mydomain:Model>
    <Element id="1">
    </Element>
    <Element id="2">
    </Element>
</mydomain:Model>


I need a separated XML file that contains only this part:
<?xml version:"1.0" encoding="UTF-8"?>
<Element id="1">
</Element>


So, I created an operation action menu in diagram and now I can call a Java service for the Element item. In that Java service, I want to create an XML file that contains only the Element item. It is possible to traverse items under Element and create my own XML file. However, I think maybe there is an already implemented method in Sirius libraries for this.

Thanks in advance.

Hi Simon,

Indeed, we have that functionality on Sirius. From the Model Explorer view, if you select a semantic element that is not at the root of your model, you have the contextual action "Control...". This will open a wizard that will lead you to create a sub-model where the selected semantic element is the root. The main model will reference the sub-model so the hierarchy is kept. The wizard will also ask you if you want to split the representations to a new representation file as well. Note that as the sub-model is of the same extension, you can export it in a new modeling project and work on it separatly.

If you still want to implement your own action to do this, you can have a look at the code of org.eclipse.sirius.business.internal.command.control.ControlCommand

Best regards,
Steve

Hello Steve, Thanks for the answer. Unfortunately, I could not achieve to create a sub-model by using Control... menu. First of all I should state that I cannot see the enabled Control... menu on semantic elements (or maybe I am confused with the meaning of semantic elements). I can see it as enabled when I right click to a diagram description item in Model Explorer. Actually, this is OK for me, but maybe this is the reason of my problems. Anyway, after I clicked to the Control... menu, the wizard requests these two preferences from me respectively:
1. . Resource URI (probably this is the file path that new representation_**.aird file will be saved)
2. Selection of representations to export. In this menu I can see all items in my model, but I can select only diagram description items.

In the second menu, when I checked the related diagram description items I am getting the following Java exceptions. If I do not check any elements, then a representation file that is linked to the actual diagram description is created. However, this file is almost empty and it cannot be used by itself. What I mean is that when I open this new representation file with a text editor, it only contains some references to the actual model.
