The first part of your JSON looks something like this when "pretty printed" --
{
"Data 1":{
"2012-12-01":[
{
"field 1":"field 2",
"summary":"summary 1"
},
{
"field":"field 2",
"summary":"summary 2"
},
{
"service":"service 3",
"summary":"summary 3"
}
],
"2012-12-10":[
{
"field":"field 1",
"summary":"summary 1"
},
{
"field":"field 2",
"summary":"summary 2"
}
],
"2012-12-31":[
{
"field":"field 1",
"summary":"summary 1"
}
]
},
"Data 2":{
"2013-01-4":[
The outermost part of the JSON is a dictionary (JSON calls it an "object") -- you can tell because of the opening {
. In that dictionary is a key/object pair called "Data 1". The object is a dictionary (another {
) whose first key/object pair is called "2012-12-01". The object of this second pair is an array (the [
) containing three dictionaries. Etc.
