> Key: ODATA-348
> URL: http://tools.oasis-open.org/issues/browse/ODATA-348
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Bug
> Components: OData CSDL
> Affects Versions: V4.0_WD01
> Environment: [Proposed]
> Reporter: Michael Pizzo
> Assignee: Ralf Handl
> Fix For: V4.0_WD01
>
>
> <edmx:Reference> allows a service's metadata document to reference external metadata descriptions in a distributed environment. This allows a large, potentially complex schema to be factored into reasonable sized chunks.
> In such an environment, one metadata document may reference multiple external metadata documents, and clients can lazily fetch metadata as required. However, today there is no way for a client to know which of possibly multiple references it needs to follow in order to resolve a particular namespace.
> If we were to require that the service explicitly specify the namespaces to be included from each reference, that would allow a client that is lazily exploring metadata to know which references it needs to follow in order to get additional metadata. This also gives us the ability to include a subset of the namespaces in a referenced document.
> This is also a convenient place to apply an alias to the namespace, which makes more sense than applying it in a <using> statement within the <schema> since the alias, in order to be valid in a url or a response, must be global which is strange for a declaration within a <schema> element.
> For example:
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <edmx:Edmx xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx";
> Version="4.0">
> <edmx:Reference Url="http://odata.org/ann/a";>
> <edmx:Include Namespace="org.example.validation" Alias="validation"/>
> <edmx:Include Namespace="org.example.display" Alias="display" />
> </edmx:Reference>
> <edmx:DataServices ...>
> </edmx:Edmx>
