EMOF to Ecore [message #128428] Fri, 08 August 2008 08:11 Go to next message

Hi,

I have an EMOF file in the XML format.I need to convert this into the
ECORE format.

A small snippet of the code is given below:

<?xml version="1.0" encoding="UTF-8"?>
<emof:Package xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmi:id="xyz"
name="xyz" >


Is there any tool,which can accept this format and give the corresponding
ecore relevant code.

If there is no tool and if I have to do it manually,how do I proceed.

Please help me in solving this issue.

Thanks,
Swetha.

Swetha,

EMOFResourceFactoryImpl creates resources implementations configured to
do this. Even the Sample Ecore Editor can do this. I.e., it can open a
*.emof file and if you do a "Save As" to a *.ecore name, it will save it
in Ecore format instead of EMOF format (or vice versa as well). With
the content type support in EMF 2.4, we've even registered the EMOF
content type for *.xmi extension so we should be able to read that...

I saw your questions on one of the other newsgroups. Likely those folks
should be supporting this directly and perhaps just need to tweak some
configuration to make it work. EMOF serializations should just be
transparently handles as an interchangeable format for Ecore...

Hi Ed,

Thanks for your reply.

I tried the following.

1.Initially I had the test.xml file which is in XML format.

2.I did a File Save As and saved it in the ecore format.

3.I tried opening this ecore file using EMF .

4.While loading the Ecore,the following Exception has been thrown.
!ENTRY org.eclipse.emf.importer 2 0 2008-08-11 09:27:24.274

I am not sure just by saving the emof file(in xml format) into ecore
format works for me.Have I missed something here.
I am currently using Eclipse Ganymede V3.4


Plz advice.

Regards,
Swetha.

You saved with a *.ecore extension using the Sample Ecore Editor which
has this logic:

public void doSaveAs()
{
SaveAsDialog saveAsDialog= new SaveAsDialog(getSite().getShell());
saveAsDialog.create();

saveAsDialog.setMessage(EcoreEditorPlugin.INSTANCE.getString ( "_UI_SaveAs_message"));
saveAsDialog.open();
IPath path= saveAsDialog.getResult();
if (path != null)
{
IFile file =
ResourcesPlugin.getWorkspace().getRoot().getFile(path);
if (file != null)
{
ResourceSet resourceSet = editingDomain.getResourceSet();
Resource currentResource = resourceSet.getResources().get(0);
String currentExtension =
currentResource.getURI().fileExtension();

URI newURI =
URI.createPlatformResourceURI(file.getFullPath().toString(), true);
String newExtension = newURI.fileExtension();

if (currentExtension.equals(ECORE_FILE_EXTENSION) &&
newExtension.equals(EMOF_FILE_EXTENSION) ||
currentExtension.equals(EMOF_FILE_EXTENSION) &&
newExtension.equals(ECORE_FILE_EXTENSION))
{
Resource newResource = resourceSet.createResource(newURI);

newResource.getContents().addAll(currentResource.getContents ());
resourceSet.getResources().remove(0);
resourceSet.getResources().move(0, newResource);
}
else
{
currentResource.setURI(newURI);
}

IFileEditorInput modelFile = new FileEditorInput(file);
setInputWithNotify(modelFile);
setPartName(file.getName());

doSave(getActionBars().getStatusLineManager().getProgressMon itor());
}
}
}

I guess so. It worked fine for me when I just tried it. You used the
Sample Ecore Editor?

Hi Ed,

I am using the TOPCASED Ver 2.0 M6.This has the Sample Ecore Editor. I
hope it's the same editor you are referring. If its not correct, can you
please tell me the link where I can download Sample Ecore Editor.

Swetha,

If you have the full EMF installed (as available in the Ganymede
modeling package or from the EMF download package) it comes with the
Sample Ecore Editor; you'll see that choice on the Open With menu. I
can't comment informatively on what's in various other distros...
