Friend of a Friend (FOAF)

Friend of a Friend (FOAF) is a standard language used to describe relationships and personal information on the web in a machine-readable way. It allows individuals to share details about themselves, their friends, and their interests so that computers can understand and connect related data across different websites. This helps improve online profiles, social networking, and data integration, enabling more personalized and interconnected digital experiences while respecting privacy controls. Essentially, FOAF formalizes how personal and social data are represented electronically, making it easier to discover and relate information about people in a consistent way.
