Need JOLT spec file for transfer of complex JSON - jolt

Question

I have a complex JSON object (I've simplified it for this example) that I cannot figure out the JOLT transform JSON for. Does anybody have any ideas of what the JOLT spec file should be?
Original JSON
[
{
"date": {
"isoDate": "2019-03-22"
},
"application": {
"name": "SiebelProject"
},
"applicationResults": [
{
"reference": {
"name": "Number of Code Lines"
},
"result": {
"value": 44501
}
},
{
"reference": {
"name": "Transferability"
},
"result": {
"grade": 3.1889542208002064
}
}
]
},
{
"date": {
"isoDate": "2019-03-21"
},
"application": {
"name": "SiebelProject"
},
"applicationResults": [
{
"reference": {
"name": "Number of Code Lines"
},
"result": {
"value": 45000
}
},
{
"reference": {
"name": "Transferability"
},
"result": {
"grade": 3.8
}
}
]
}
]
Desired JSON after transformation and sorting by "Name" ASC, "Date" DESC
[
{
"Name": "SiebelProject",
"Date": "2019-03-22",
"Number of Code Lines": 44501,
"Transferability" : 3.1889542208002064
},
{
"Name": "SiebelProject",
"Date": "2019-03-21",
"Number of Code Lines": 45000,
"Transferability" : 3.8
}
]

I couldn't find a way to do the sort (I'm not even sure you can sort descending in JOLT) but here's a spec to do the transform:
[
{
"operation": "shift",
"spec": {
"*": {
"date": {
"isoDate": "[#3].Date"
},
"application": {
"name": "[#3].Name"
},
"applicationResults": {
"*": {
"reference": {
"name": {
"Number of Code Lines": {
"#(3,result.value)": "[#7].Number of Code Lines"
},
"Transferability": {
"#(3,result.grade)": "[#7].Transferability"
}
}
}
}
}
}
}
}
]
After that there are some tools (like jq I think) that could do the sort.
