Query2 was introduced during 12.04 as a new feature for machine read-able format. While the new JSON format describes the images, it is rather unweildy. In light of that, it is proposed to deprecate the new format and introduce a simplified format which is based on request.

The new format will return results based on URL, for example: data=cloud&distro=lucid&arch=amd64&stream=server&instance_type=ebs&region=ap-southeast-1

Will return: {     "request": {         "allactive": "1",         "arch": "amd64",         "bad_asks": [],         "cloud": "EC2",         "data": "cloud",         "distro": "lucid",         "instance_type": "ebs",         "region": "ap-southeast-1",         "release_tag": "release",         "stream": "server"     },     "response": [         {             "arch": "amd64",             "build_date": "2012-09-13",             "build_id": "D87316017B9FF4490EF14CB7119E8995",             "build_serial": "20120913",             "build_type": "server",             "cloud_name": "EC2",             "distro_code_name": "lucid",             "distro_name": "Lucid Lynx",             "distro_version": "10.04",             "instance_type": "ebs",             "kernel_id": "aki-11d5aa43",             "latest_build": true,             "published_date": "2012-09-13",             "published_id": "ami-903575c2",             "published_url": "https://console.aws.amazon.com/ec2/home?region=#launchAmi=ami-903575c2",             "ramdisk_id": "None",             "region_name": "ap-southeast-1",             "release_tag": "release",             "response_type": "cloud"         },         {             "arch": "amd64",             "build_date": "2012-07-26",             "build_id": "9CF68D8D8D3F9B9D529A0BA3FDE64B94",             "build_serial": "20120724",             "build_type": "server",             "cloud_name": "EC2",             "distro_code_name": "lucid",             "distro_name": "Lucid Lynx",             "distro_version": "10.04",             "instance_type": "ebs",             "kernel_id": "aki-11d5aa43",             "latest_build": false,             "published_date": "2012-07-26",             "published_id": "ami-786d2c2a",             "published_url": "https://console.aws.amazon.com/ec2/home?region=#launchAmi=ami-786d2c2a",             "ramdisk_id": "None",             "region_name": "ap-southeast-1",             "release_tag": "release",             "response_type": "cloud"         },         {             "arch": "amd64",             "build_date": "2012-04-03",             "build_id": "BB64C065F8912EAC3947D7407FCC3F68",             "build_serial": "20120403",             "build_type": "server",             "cloud_name": "EC2",             "distro_code_name": "lucid",             "distro_name": "Lucid Lynx",             "distro_version": "10.04",             "instance_type": "ebs",             "kernel_id": "aki-11d5aa43",             "latest_build": false,             "published_date": "2012-04-03",             "published_id": "ami-6c6f283e",             "published_url": "https://console.aws.amazon.com/ec2/home?region=#launchAmi=ami-6c6f283e",             "ramdisk_id": "None",             "region_name": "ap-southeast-1",             "release_tag": "release",             "response_type": "cloud"         },         {             "arch": "amd64",             "build_date": "2012-02-21",             "build_id": "98BD8363A17C49562E89D52DF2F05097",             "build_serial": "20120221",             "build_type": "server",             "cloud_name": "EC2",             "distro_code_name": "lucid",             "distro_name": "Lucid Lynx",             "distro_version": "10.04",             "instance_type": "ebs",             "kernel_id": "aki-11d5aa43",             "latest_build": false,             "published_date": "2012-02-21",             "published_id": "ami-7089cd22",             "published_url": "https://console.aws.amazon.com/ec2/home?region=#launchAmi=ami-7089cd22",             "ramdisk_id": "None",             "region_name": "ap-southeast-1",             "release_tag": "release",             "response_type": "cloud"         }     ],     "vendor": {         "name": "Canonical Group, Ltd.",         "product": "Ubuntu Cloud Images",         "product_eula": "http://www.ubuntu.com/project/about-ubuntu/licensing",         "product_url": "http://www.ubuntu.com"     },     "version": {         "epoch": 1348259881,         "uuid": "7c057ef45e1543df8d538bd55d466733"     } }
