             Summary: Introduce $this for referencing current item in $select/$expand options
                 Key: ODATA-1116
                 URL: https://issues.oasis-open.org/browse/ODATA-1116
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Bug
          Components: ABNF Construction Rules, Protocol, URL Conventions
    Affects Versions: V4.01_CSD01
         Environment: [Proposed]
            Reporter: Michael Pizzo
             Fix For: V4.01_CSD02


In OData-1105 we introduced $select options which enabled filtering a collection of structural properties.  Where the collection is a collection of complex types, you can now do something like:

Customers?$select=Addresses($filter=City eq 'Paris')

However, we don't have a way to filter primitive types.

We also don't have a way, in $select or $expand, to pass the current item into a function without binding the function to the type of the current item.

We already have $it that references the resource identified by the last segment of the resource path, but in this case we want to reference the property on which the select/expand options are specified.
