Michael Pizzo commented on ODATA-920:
-------------------------------------

Capturing Hubert's idea of substituting the overflow value within the array with an object containing the annotation.. i.e.;

"numbers" : [
     1,
     2,
     {"@odata.numericOverflow":"-INF"},
     4
]

or, more generally, accounting for any arbitrary annotation with or without a value:

"numbers" : [
     1,
     2,
     {
        "value":3,
        "@my.comment":"this is just a guess"},
      },
     4
]

Note that, in JSON Schema, we would have to describe this as an array of numeric values or objects, using either a generic object, an "annotatedPrimitive" object that allowed an optional primitive value and zero or more annotations, or a specific "annotatedNumeric" object that allowed an (optional) numeric value and zero or more annotations.  i.e.;

                    "type": "array",
                    "items": [
                          {
                              "type": "numeric",
                              "format": "decimal"
                           },
                           "annotatableDecimal"
                     ],

where "annotatableDecimal is defined something like:

"annotatableDecimal" : {
          "type": "object",
          "properties": {
              "value": {
                  "type": "number",
                  "format": "decimal"
              }
            },
            "patternProperties": { 
                "^([a-zA-Z_][a-zA-Z0-9_]*)?@([a-zA-Z_][a-zA-Z0-9_.]*\\.)?[a-zA-Z_][a-zA-Z0-9_.]+$" : {
                                    "type": ["array", "boolean", "number", "null", "object", "string"],
                                    "description": "An annotation on the primitive value"
            }
       }
}


For annotating a collection within a collection of collections, this would presumably look something like:

"cells": [
   [
       {"foo":1,"bar":1},
       {"foo":2,"bar":2}
   ],
   { 
       "value": [
             {"foo":3,"bar":3},
             {"foo":4,"bar":4}
        ],
        "@my.annotation":"myannotationvalue"
    }
]
