Services

A number of large-scale services do interesting things with FOAF data. Some of the services are RDF-oriented pieces of infrastructure, others are from a more traditionally consumer-facing angle.

RDF indexes: SWSE, Falcons, Sindice, Swoogle, PTSW.

Google's Social Graph API indexes all the public FOAF data in the Web, as well as the XFN Microformat.

Yahoo's SearchMonkey also has support for FOAF, as does OpenLink's Virtuoso product. Garlik's QDos system includes a FOAF search facility, a FOAF builder tool, and various other services. The foaf-search.net site offers search/browse for several million crawled FOAF files. The Yandex search engine (wikipedia) has some support for FOAF, and also defines some FOAF extensions (docs, press).
