Hi there,
The input for the source model(ecore) is xml and output from the target model(ecore) is xmi. Transformation is written in ATL.

Source: XML->ecore model
Transformation: ATL
Target: ecore ->xmi

Step1) I have xml input file(data.xml):

<?xml version="1.0"?>
<DeviceItem
Name="ppp1"
IsSelected="false"

<ModuleList>
<ModuleItem
Name="m1"
IsSelected="false"
ModuleReference="Rm1">
</ModuleItem>
<ModuleItem
Name="m2"
IsSelected="false"
ModuleReference="Rm2">
</ModuleItem>
<ModuleItem
Name="m3"
IsSelected="false"
ModuleReference="Rm3">
</ModuleItem>
<ModuleItem
Name="m4"
IsSelected="false"
ModuleReference="Rm4">
</ModuleItem>
</ModuleList>

</DeviceItem>

Step2) I created XML schema for this input file and then created ecore model using eclipse EMF project(source model).

Step3)I created another ecore model(target model) and wrote the transformation in ATL.

Error: Error loading data.xml: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'null' not found.

Can someone find/hint how to solve this issue?

Thanks in advance
Kosala

Kosala,

If your package is one that corresponds to XML schema without a
targetNamespace (which appears to be the case, given there are no
namespace in your XML), it's important that you register the generated
XyzResourceFactoryImpl to handle reading of your data file.
