GoodRobot server supports XML (EEML) as the data format and is also the default data format. It also supports EEMLx XML, the details of which is available here.

EEML Overview

From the website  http://www.eeml.org/, EEML is a markup language that describes the data output of sensors and actuators, often in an architectural context but also in interactive environments and interface devices.... So that everyone talks the same EEML 'language', a schema has been written in XML for formatting data streams from sensors and devices. This provides a simple yet sophisticated structure for formatting environmental data, in the widest sense possible.

The XML schema for EEML is located at  http://www.eeml.org/xsd/005/005.xsd.  Minimal and  complete examples of EEML is located at the URLs mentioned. GoodRobot will use this XML schema (EEML) for all its API. EEML is used by several devices in environments including  Pachube and can help easily connecting to GoodRobot environment.

Sample EEML example

A sample XML (EEML) is listed below. In this example, a robot sends its positional and movement response and includes the HTTP headers.
