Step1:1 - ".emu" file format without policy

I want to structure the ".emu" file more simple and easy to process, decided to use the JSON format (as Amazon) and came up with following formats for Buckets and Object. Right now this format is more theoretical, it will be updated iteratively.

Once this format is applied for the Buckets and Objects, planning to include Policy also.


Bucket Format


|- myBucket
|- .emu -> Json file represents bucket properties

{ "bucketname": {
"accessControlList": [
{ "ID": "a9a7b886d6fd24a52fe8ca5bef65f89a64e0193f23000e241bf9b1c61be666e9", "DisplayName":"chriscustomer", "Permission": "FULL_CONTROL"},

{ "ID": "a9a7b886d6fd24a52fe8ca5bef65f89a64e0193f23000e241bf9b1c61be666e9", "DisplayName":"chriscustomer", "Permission": "FULL_CONTROL"},
],
"AWSAccessKeyId": "AWS87289288929829kkjkhS88",
"timestamp": "2010-10-02 11:00:00",
"signature": "AAAAAAAAAAAAAAAAAAAAAAAAAAA",
"objectCount": "0"
}
}

Object Format


|- Object1
|- Object2
|- Key1/Object3
|- Key2/Object4
|- ".emu"
