FOAF

FOAF is one of the key components of the WebID specifications, in particular for the WebID+TLS protocol, which was formerly known as FOAF+SSL. ==Deployment==

Although it is a relatively simple use-case and standard, FOAF has had limited adoption on the web. For example, the Live Journal and DeadJournal blogging sites support FOAF profiles for all their members, My Opera community supported FOAF profiles for members as well as groups. FOAF support is present on Identi.ca, FriendFeed, WordPress and TypePad services. Yandex blog search platform supports search over FOAF profile information. Prominent client-side FOAF support was available in Safari web browser before RSS support was removed in Safari 6 and in the Semantic Radar plugin for Firefox browser. Semantic MediaWiki, the semantic annotation and linked data extension of MediaWiki supports mapping properties to external ontologies, including FOAF which is enabled by default. There are also modules or plugins to support FOAF profiles or FOAF+SSL authorization for programming languages, as well as for content management systems. ==Example==

The following FOAF profile (written in Turtle format) states that James Wales is the name of the person described here. His e-mail address, homepage and depiction are web resources, which means that each can be described using RDF as well. He has Wikimedia as an interest, and knows Angela Beesley (which is the name of a 'Person' resource). @prefix rdf: . @prefix rdfs: . @prefix foaf: . a foaf:Person ; foaf:name "James Wales" ; foaf:mbox ; foaf:homepage ; foaf:nick "Jimbo" ; foaf:depiction ; foaf:interest ; foaf:knows [ a foaf:Person ; foaf:name "Angela Beesley" ] . rdfs:label "Wikimedia" . ==History==
