How to convert XSD to Ecore (EMF)

问题

What is the best way to convert .xsd-files into .ecore-files?

Is there an Eclipse plugin for that?

回答1:

That's what worked for me:

New -> Project...
Eclipse Modeling Framework -> EMF Project
Model Importers: XML Schema
Model URIs: [Select xsd-File]

To revalidate the .ecore-File when xsd has changed:

Right-Click on .genmodel-File
Reload...

If you do not want to create a new MDT project every time you want to import a schema as ECore model then there is also another way to do this:

New -> EMF Generator Model (in "Eclipse Modelling Framework")
Press Next
Select folder and specify filename (has to have the extension "genmodel")
Press Next
Select "XML Schema" as model importer
Press Next
Select URI to your XSD
(Optionally, select tick box "Create XML Schema to Ecore Map" if you want to generate a .xsd2ecore map file)
Press Next
Select all desired root packages
Press Finish

An example class. I did not clean up the imports.

 

import org.eclipse.emf.common.util.URI;

import java.io.IOException;
import java.util.Collection;
import java.util.Iterator;

import org.eclipse.emf.ecore.*;
import org.eclipse.xsd.*;
import org.eclipse.xsd.ecore.XSDEcoreBuilder;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.emf.ecore.xmi.*;
import org.eclipse.emf.ecore.xmi.impl.XMIResourceFactoryImpl;
import org.eclipse.emf.edit.ui.*;


public class Xsd2Ecore {

    public static void main(String[] args) {
        Xsd2Ecore x2e = new Xsd2Ecore();
        x2e.go("UMLVersions/V1.0.0/UML2XMI.xsd", "UMLVersions/V1.0.0/UML2100.xmi");
    }


    public void go(String sourcename, String targetname) {

        System.out.println("Starting");

        XSDEcoreBuilder xsdEcoreBuilder = new XSDEcoreBuilder();
        ResourceSet resourceSet = new ResourceSetImpl();
        Collection eCorePackages = xsdEcoreBuilder.generate(URI.createFileURI(sourcename));

        resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", new XMIResourceFactoryImpl());
        Resource resource = resourceSet.createResource(URI.createFileURI(targetname));

        for (Iterator iter = eCorePackages.iterator(); iter.hasNext();) {
            EPackage element = (EPackage) iter.next();
            resource.getContents().add(element);
        }

        try {
            resource.save(null);
        } catch (IOException e) {
            e.printStackTrace();
        }

        System.out.println("Finished");

    }

}

Have you tried

eclipse –console –noExit –noSplash -data C:\temp\emf-ws
    -application org.eclipse.xsd.ecore.importer.XSD2GenModel

It generates .ecore and .genmodel for your set of XSDs.
