picoformats
Picoformats represent an effort being undertaken by Chris Messina and Andy Stack of Mozes to codify various standards and openly pursue a nomenclature and syntax for communicating and executing commands with mobile devices over SMS.
An example application is Dodgeball's use of the at symbol (@) to express checking in to a place.
Using the Microformats process and principles of building block design, our goal is to openly develop a complete syntax for interacting with various mobile services using the characters available on most mobile devices.
