The schema location in the generated schema will try to create a
relative path between the absolute path of the schema you are
generating, typically platform:/resource/<project>/model/Xyz.xsd, and
the absolute URI of the schema being referenced, which appears to be
"file:/C:/working/eclipse/cars/parts.xsd". Since that's not possible, an
absolute URI would be used. But, if you export to the same folder, so
that a relative path correctly resolves, then that relative path should
be generated. (I wonder if when you import from a schema, the GenModel
should already be set up as if it exports to that same location?) What
I would typically expect is that each model exports a schema to its
model folder and hence references between model schemas will typically
be of the form ../../<other-project/model/Xyz.xsd.

The schema location in the generated schema will try to create a
relative path between the absolute path of the schema you are

model folder and hence references between model schemas will typically
be of the form ../../<other-project/model/Xyz.xsd.

Hi Ed,
Using the default settings and doing a straight import and export from one
genmodel to the same folder I do get the relative schemaLocation. An example
of the result is below.
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:parts="http://www.acme.com/parts"
xmlns:vehicles="http://www.acme.com/vehicles"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
ecore:documentRoot="DocumentRoot" ecore:nsPrefix="vehicles"
ecore:package="com.acme.vehicles"
targetNamespace="http://www.acme.com/vehicles">
<xsd:import namespace="http://www.acme.com/parts"
schemaLocation="platform:/resource/trans/model/parts.xsd"/ >
<xsd:element name="car" type="vehicles:car_._type"/>
<xsd:complexType ecore:name="CarType" name="car_._type">
<xsd:sequence>
<xsd:element ref="parts:wheel"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
Q1. My problem is how to get schemaLocation="parts.xsd" instead of
schemaLocation="platform:/resource/trans/model/parts.xsd"/ >.
The URI scheme of "platform" is not suitable for producing a schema for
other tools to digest.
Q2. Can I do this using annotations on the genmodel?
Thanks for the quick response. - Matthew
