Representational State Transfer
- application state and functionality are divided into resources
- resources are uniquely addressable using a universal syntax (e.g. URIs)
- all resources share a uniform interface for the transfer of state between
client and resource (e.g. HTTP)
- behind the scenes with Live HTTP Headers
