             Summary: Support Arrays of Arrays
                 Key: ODATA-879
                 URL: https://issues.oasis-open.org/browse/ODATA-879
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Bug
          Components: OData CSDL, OData JSON Format
    Affects Versions: V4.0_ERRATA02
            Reporter: Michael Pizzo
             Fix For: V4.01_WD01


There are scenarios where it's convenient to represent something as an array of arrays. In JSON this would look as:

[["foo1","bar1"],["foo2","bar2"]]
or
[[{"foo":"foo1"},{"bar":"bar1"}],[{"foo":"foo2"},{"bar":"bar2"}]]

Currently services must represent these as arrays of complex types that have array properties. In JSON, the result looks like:

[{"value":["foo1","bar1"]},{"value":["foo2","bar2"]}]
or
[{"value":[{"foo":"foo1"},{"bar":"bar1"}]},{"value":[{"foo":"foo2"},{"bar":"bar2"}]}]

If we are trying to make JSON representation as close as possible to a custom representation we would need to support the former syntax (without the "value" objects).

One problem with arrays of arrays in JSON is that we don't have a way to annotate the (array) items within the array. For example, we couldn't add count, nextLink, etc. for the inner arrays..
