Friend of a Friend

FOAF is a project devoted to linking people and information using the Web. Regardless of whether information is in people's heads, in physical or digital documents, or in the form of factual data, it can be linked. FOAF integrates three kinds of network: social networks of human collaboration, friendship and association; representational networks that describe a simplified view of a cartoon universe in factual terms, and information networks that use Web-based linking to share independently published descriptions of this inter-connected world.

FOAF项目致力于通过互联网将人物与信息进行关联。无论信息存储于人们的头脑之中，物理或数字文档之中，抑或是以事实数据的形式呈现，皆可进行链接。FOAF整合了三种类型的网络：人类在协作、友谊和关联方面的社交网络；以事实术语描述的简化卡通宇宙的表征网络，以及利用基于网络的链接来共享独立发布的关于这一互联世界的描述的信息网络。
