This document discusses the convergence of social networks and semantic web technologies like FOAF, OpenID, and OAuth. It provides a brief history of semantic web projects and social networking sites. It then explains how standards like FOAF, OpenID, and OAuth allow for decentralized social applications and a unified social graph by describing identities, connections between people, and permissions for sharing data across sites. The document suggests the emerging social web will focus more on groups than individuals and leverage evidence-based friend lists identified by OpenID and described by FOAF across multiple sites using OAuth.
