How can I annotate the genmodel to generate the correct schemaLocation value
for an import?

I successfully generate an eCore model and genmodel from this schema.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns="http://www.acme.com/vehicles"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ns1="http://www.acme.com/parts"
targetNamespace="http://www.acme.com/vehicles"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:import namespace="http://www.acme.com/parts"
schemaLocation="Parts.xsd"/>
<xs:element name="car">
<xs:complexType>
<xs:sequence>
<xs:element ref="ns1:wheel"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

From the eCore model I want to export the model to an XSD. When I export I
get this schema.
<?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="file:/C:/working/eclipse/cars/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>

How can I make the value of the schemaLocation in the import be the relative
location of "parts.xsd"? I do not want "platform" as the scheme for my URIs.
I want to do this using annotations/detail on the genmodel rather than
coding around it.

Matthew,

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.

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
