Techopedia Explains FOAF
Part of the idea behind FOAF is that semantic Web technologies and new syntactical systems facilitate a kind of “revolution” in data connection. Internet guru Tim Berners-Lee has written about how technologies like FOAF will change the ordering of data systems. One example is the use of FOAF in JSON-LD, a resource for adding linked data to online data models.
