Format of tracked fields in time series

The tracked fields that are associated with a tracking group are listed as entries of a JSON object that is bound to the trackedFields attribute of the activity timeSeries object or the tracking timeSeries object.

That JSON object has the following format.
"trackedFields":{
        "trackedFieldName1.trackedFieldType1": trackedFIeldValue1,
        "trackedFieldName2.trackedFieldType2": trackedFIeldValue2,
        "trackedFieldName3.trackedFieldType3": trackedFIeldValue3,
        …
        }
The key is the concatenation of the tracked field name and its type (boolean, decimal, double, float, integer, string), separated with a dot. The value is the tracked field value in a format that matches the type.
"trackedFields": {
        "claimId.string": "9.152.116.48.1527774200016.1579group5",
