This is an XFN file

XFN (XHTML Friends Network) is a simple way to represent human relationships using hyperlinks. In recent years, blogs and blogrolls have become the fastest growing area of the Web. XFN enables web authors to indicate their relationship(s) to the people in their blogrolls simply by adding a 'rel' attribute to their tags.

XFN - Xhtml Friends Network

This is an attempt to extract RDF/FOAF form XFN marked XHTML. For example, I assert here that I know Dan Brickley and Leigh Dodds. Each <a> element contains rel attribute with relevant XFN relationship value.

A sample XLST file provided to extract FOAF/RDF from this file. Use W3C online XSLT service, or if it doesn't work (sometimes shows '502 Proxy Error'), try this local conversion.

This XLST assumes:

• The mail address of the author is provided via <link> element whose rev attribute has value "made", and href attribute has mbox uri.
• href attribute of each <a> element (with XFN rel) has a uri of the friend's homepage (hence, foaf:homepage). This could be foaf:weblog.
• The content of above <a> element is the name of the person
• Optionally, if a <meta> element with name="author" presents, use its content as the name of the subject foaf:Person

Similar approach found at the discussion by Dan Connolly, and his XLST grokXFN.xsl.
