Use Case: AJAX web front-end directly calling API

• Name: AJAX web front-end directly calling API
• Contact: Richard Davies, ElasticHosts.
• Description: A cloud provider implements their customer web front-end as an entirely client-side AJAX application calling the OCCI API directly.
• Functional Requirements
  • Completeness: API must be contain complete set of calls to completely specify and control cloud (but this is likely only ~15-20 verbs on ~3-4 nouns!)
  • Responsiveness: Calls must return swiftly. In particular, we should provide a simple and quick call to poll the _list_ of servers, drives, etc. that exist without listing all of their properties, since this is computationally much cheaper for the cloud to return, and will need to be regularly polled to catch any servers, etc. that are created outside of the interface.
• Non-functional Requirements
  • Syntax: A simple JSON syntax for the API will make the AJAX interface much simpler to implement
