The Friend of a Friend (FOAF) project is creating a Web of machine-readable pages describing people, the links between them and the things they create and do.
"SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF. Currently, we have simple prototypes of a publishing and an aggregating service, less than 100 lines of PHP code each."
