The XML Soccer Ruby Library by Kavinder Dhaliwal is a Ruby Wrapper for the XML Soccer API. The XML Soccer API is a web service that collects soccer data and makes the information available in XML to subscribers of the service.
BodyMedia provides insight into your body’s physical state through four scientific measurements. It uses a pedometer-like device to measure physical motion and steps, but also has galvanic skin response, skin temperature and heat flux measures. The BodyMedia API will give application developers access to all these metrics on your body’s recent activity. FitBit is in a similar space, but FitBit just doesn’t have as many measurements to use in its applications.
