> In OData-1046 we approved addition of a JSON-format for Batch requests and responses.
> In the discussion we considered a format that included groups of requests as top-level JSON objects with common batch options.
> We can simplify this proposal by removing this outer grouping and allowing the individual requests to specify that they are part of a particular atomicityGroup. By adding additional semantics (members of an atomicityGroup must be adjacent in a request) we can simplify construction and processing of a batch request.
> Example batch request:
> POST /v1.0/$batch HTTP/1.1  
> {
>   requests: [
>     {
>       id: "1",
>       atomicityGroup: "atom1",
>       method: "post",
>       url: "/users",
>       headers: {
>         "Content-Type": "application/json"
>       },
>       body: {
>         displayName: "John Smith",
>         userPrincipalName: "jsmith@contoso.com"
>       }
>     },
>     {
>       id: "2",
>       atomicityGroup: "atom1",
>       dependsOn: ["1"],
>       method: "put",
>       url: "$1/photo",
>       headers: {
>         Content-Type: "image/jpeg"
>       },
>       body: "FRwvAAIAAAANAA4AFAAhAPNTUAAAAAAAAAAAAAAQUAAAAAAADHrQX+"
>     },
>     {
>       id: "3",
>       method: "get",
>       url: "/groups?top=10",
>       headers: {
>         Accept: "application/atom+xml",
>       }
>     },
>     {
>       id: "4",

> }
> {
