Melange API Specification

General Information

The Melange API is implemented using a RESTful web service interface.

* All GET /resources accepts 'limit' and 'marker' params. If these params are not passed default limit is applied.

* If POST or PUT on a resource doesn't send mandatory params, API returns '400 Bad Request' response.

Request/Response Types

* The Melange API supports both the JSON and XML data serialization formats.

* The request format is specified using the Content-Type header and is required for operations that have a request body.

* The response format can be specified in requests using either the Accept header or adding an .xml or .json extension to the request URI.

* If no response format is specified, JSON is the default.

* If conflicting formats are specified using both an Accept header and a query extension, the query extension takes precedence.

Extensions

The Melange API is extensible. The API Extensions allow introducing new features in the API without requiring a version change and allows vendor specific niche functionality. The API extensions work similar to nova extensions.

To Be Done:

* Add 'self' and 'bookmark' links in resource details.

* Versions atom feed

* API to list all IPs by an instance_id
