Subject: [OASIS Issue Tracker] Updated: (ODATA-12) create a data type for property names
[ http://tools.oasis-open.org/issues/browse/ODATA-12?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ralf Handl updated ODATA-12:
----------------------------
Proposal:
Introduce "primitive types" Edm.Property and Edm.NavigationProperty that can only be used in the Type attribute of a Term or a property of a complex type that is used as the type of a term.
Add new attributes Xxx and NavigationProperty to Annotation and PropertyValue with the same syntax as the Path attribute:
<Annotation Term="Temporal.ApplicationPeriod">
<PropertyValue Property="StartPeriod" Xxx="bus_start" />
<PropertyValue Property="EndPeriod" Xxx="bus_end" />
</Annotation>
<Annotation Term="RelatedStuff" NavigationProperty="Suppliers" />
<Annotation Term="LookOverThere" Xxx="SupplierName" />
Unfortunately the canonical name for Xxx is Property, and that is already taken in PropertyValue.

> Project: OASIS Open Data Protocol (OData) TC

> Components: OData CSDL v1.0
> Affects Versions: WD01

> Priority: Minor
> Fix For: WD01

>
> 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:
> <Annotation Term="Temporal.ApplicationPeriod">
> <PropertyValue Property="StartPeriod" String="bus_start" />
> <PropertyValue Property="EndPeriod" String="bus_end" />
> </Annotation>
> Instead of declaring StartPeriod and EndPeriod to be of type String, we could declare them to be of type PropertyName.
