Subject: [OASIS Issue Tracker] (ODATA-879) Support Arrays 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.. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
