FOAF was designed to be used alongside other such dictionaries ( schemas or ontologies ), and to beusable with the wide variety of generic tools and services that have been created for the Semantic Web. As such it describes the FOAF vocabulary and the terms (RDF classes and properties) that constitute it, so that Semantic Web applications can use those terms in a variety of RDF-compatible document formats and applications. The FoafVocab page in the FOAF wiki lists a number of extension vocabularies that are particularly applicable to use with FOAF. Meanwhile Leigh Dodd s foaf-a-matic has been the data creation tool that has been most people s gateway to FOAFdom.

Abstract This specification describes the FOAF language, defined as a dictionary of named properties and classes using W3C s RDF technology. Secondly, there are mechanisms for saying which RDF properties are connected to which classes, and how different classes are related to each other, using RDF Syntax and OWL. FOAF is now arguably better documented in Japanese and Spanish than in English, thanks to Masahide Kanzaki and Leandro Mariano Lopez (inkel) respectively. 0 etc can also be mixed in with FOAF terms, as can local extensions.

This means that SAX and DOM XML parsers are not adequate to deal with RDF/XML. For a good general introduction to FOAF, see Edd Dumbill s article, XML Watch: Finding friends with XML and RDF (June 2002, IBM developerWorks). It doesn t really matter what filename you choose for your FOAF document, although foaf. Information about the use of FOAF with image metadata is also available. The FOAF RDF namespace, by contrast, is fixed and it s identifier is not expected to change. com domain name and associated documentation. Evolution and Extension of FOAF The FOAF vocabulary is identified by the namespace URI http://xmlns. FOAF also owes a lot to the folks at Ecademy, TypePad and elsewhere for showing how end users can share FOAF self-descriptions on the Web without ever seeing a line of XML syntax. .
