Summary: Support for predefinedNamespaces in Edm Metadata
Key: OLINGO-1197
URL: https://issues.apache.org/jira/browse/OLINGO-1197
Project: Olingo
Issue Type: New Feature
Components: odata2-annotation
Affects Versions: (Java) V4 4.4.0
Reporter: Michael Jung
Priority: Minor
Hi,
org.apache.olingo.odata2.core.ep.producer.XmlMetadataProducer.getMetadata is
called from
org.apache.olingo.odata2.core.edm.provider.EdmServiceMetadataImplProv.getMetadata
always without handing over predefinedNamespace.
This produces ugly metadata as the namespace is repeated in all properties,
e.g.:
<Property xmlns:sap="http://www.sap.com/Protocols/SAPData"; Name="ID"
Type="Edm.String" sap:label="Identifier"/>
<Property xmlns:sap="http://www.sap.com/Protocols/SAPData"; Name="DESC"
Type="Edm.String" Nullable="true" sap:label="Description"/>
I would see a possible fix in the addition of a getPredefinedNamespace method
in the EdmProvider class, and calling this in
EdmServiceMetadataImplProv.getMetadata to provide it to the
XmlMetadataProducer. I do not fully grasp the usage of EdmProvider
