------------------------------------

             Summary: Clarify datatype of virtual property $count
                 Key: ODATA-1215
                 URL: https://issues.oasis-open.org/browse/ODATA-1215
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: Extension for Data Aggregation
    Affects Versions: V4.0_CS02
         Environment: Proposed
            Reporter: Gerald Krause
             Fix For: V4.0_CSD04


In the Data Aggregation extension, the virtual property $count has type Edm.Decimal. In contrast the JSON Format specification states that the result of the system query option has type Edm.Int64.

Since aggregation rather reduces the number of entities in a result collection, question is whether there is some unmentioned reason for this discrepancy.
