ECore to XSD roundtripping question regarding keys [message #431175]

Hi all,

The following EReference

<eStructuralFeatures xsi:type="ecore:EReference" name="field"
upperBound="-1"
eType="#//Field" containment="true" resolveProxies="false"
eKeys="#//NamedEntity/name">
<eAnnotations
source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="kind" value="element"/>
<details key="name" value="field"/>
<details key="namespace" value="##targetNamespace"/>
</eAnnotations>
</eStructuralFeatures>

is exported to XSD as follows:

<xsd:element ecore:keys="name" form="qualified" maxOccurs="unbounded"
minOccurs="0" name="field" type="appmodel:Field"/>

(and correctly imported back to ECore)

OTH, the following EReference

<eStructuralFeatures xsi:type="ecore:EReference" name="field"
lowerBound="1" eType="#//Reference"
eKeys="#//NamedEntity/name">
<eAnnotations
source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="kind" value="attribute"/>
<details key="name" value="field"/>
</eAnnotations>
</eStructuralFeatures>

is exported to XSD as:

<xsd:attribute ecore:reference="appmodel:Reference" name="field"
type="xsd:anyURI" use="required"/>

loosing the key information :(
(the only difference between the two is the multiplicity)

Anything to look for?

Adrian.

Adrian,

Looks like an oversight. Perhaps only supporting it for elements or
only for containment references. Please open a bugzilla.
