Summarized from the xmlns FOAF specs
FOAF stands for ‘friend of a friend’
FOAF is a project devoted to linking people and information using the Web… If people publish information in the FOAF document format, machines will be able to make use of that information. If those files contain “see also” references to other such documents in the Web, we will have a machine-friendly version of today’s hypertext Web.
It is a way of creating a semantically meaningful network of objects, useful for enabling the Semantic Web.
- FOAF descriptions are published as linked documents in the Web
- The result of the FOAF project is a network of documents describing a network of people (and other stuff).
Example FOAF describing a person (using RDF)
It basically says, “there is a foaf:Person with a foaf:name property of ‘Dan Brickley’; this person stands in foaf:homepage and foaf:openid relationship to a thing called http://danbri.org/ and a foaf:img relationship to a thing referenced by a relative URI of /images/me.jpg
