    [ http://tools.oasis-open.org/issues/browse/ODATA-12?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31125#action_31125 ] 

Ralf Handl commented on ODATA-12:
---------------------------------

Yet another approach would be to define a core annotation

<Schema Namespace="OData.Core"> 
  <ValueTerm Name="IsPropertyName" Type="Boolean" DefaultValue="true" /><!-- Thanks to ODATA-95 -->
</Schema>

<Schema Namespace="OData.Temporal"> 
  <ComplexType Name="Period"> 
    <Property Name="StartPeriod" Type="String" Nullable="False"> 
      <ValueAnnotation Term="OData.Core.IsPropertyName"/>
    </Property>
    <Property Name="EndPeriod" Type="String" Nullable="False"> 
      <ValueAnnotation Term="OData.Core.IsPropertyName"/>
    </Property>
  </ComplexType> 

  <ValueTerm Name="ApplicationPeriod" Type="Temporal.Period"> 
</Schema> 

Now Annotation Editing tools caninterpret the core annotation and provide code completion and syntax check to annotation authors.

> The Edm.String data type can be used to define a type annotation property when the property will hold the name of some other property. A more specific data type could be added to OData for this purpose.
> In the OData Extension for Temporal Data we suggested this annotation:
> <TypeAnnotation Term="Temporal.ApplicationPeriod">
>    <PropertyValue Name="StartPeriod" String="bus_start" />
>    <PropertyValue Name="EndPeriod" String="bus_end" />
> </TypeAnnotation>
> Instead of declaring StartPeriod and EndPeriod to be of type String, we could declare them to be of type PropertyName.
