Martin Zurmuehl updated ODATA-773:
----------------------------------

        Fix Version/s: V4.0_ERRATA03
                           (was: V4.0_CSD04)
    Affects Version/s: V4.0_ERRATA02
                           (was: V4.0_CS02)
          Description: 
The CSDL specification states in http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part3-csdl/odata-v4.0-errata02-os-part3-csdl-complete.html#_Toc406009991 that:
"Metadata annotations can be used to define additional characteristics or capabilities of a metadata element (...). Instance annotations can be used to define additional information (...). Where the same annotation is defined at both the metadata and instance level, the instance-level annotation overrides the annotation specified at the metadata level."
The ATOM format specification is incomplete because it do not allow overriding metadata-level annotations <b> that use a qualifier </b>, because qualifiers in instance annotations are not supported by the JSON format.
See also Jira Ticket OData-772 and OData-774.

             Proposal: Extend the JSON rules for instance annotations in 18.1 and 18.2 (see http://docs.oasis-open.org/odata/odata-json-format/v4.0/errata02/os/odata-json-format-v4.0-errata02-os-complete.html#_Toc403940652) by “optionally followed by a hash (#) character and a qualifier for the term”.  (was: Extend the ATOM format <metadata:annotation> element with a "qualifier" attribute.)
          Component/s: OData JSON Format
                           (was: OData ATOM Format)
