I recently stumbled over an IEEE Internet Computing article [1] that happens to mention RDFa. I was pleased to read it. However, the authors managed to cite a quite old RDFa revision (May 2006) and gave an IMHO odd explanation of RDFa (incl. some minor 'bugs'). So, I'm rather disappointed about the message that is now conveyed with this part of the article. But please have a look at it yourself and do form your own opinion. Source: IEEE Internet Computing, September/October 2007 (Vol. 11, No. 5), pp. 17-25, Requirements and Services for Metadata Management [1]. Citation (p 21, 'Current Metadata-Management Approaches and Technologies): "[...] One of the most common ways to include metadata in HTML or XHTML documents is to use the <meta> element anywhere in the document, as Ben Adida and Mark Birbeck describe [REF-6]. This element allows the description of document properties using property-value pairs. Normative properties include author, expiration date, keyword lists, and so on, although we can use other user-defined properties (such as those from Dublin Core). [...] XHTML 2.0 [REF-7] proposes an alternative way to link entities and their descriptions so that metadata isn't intertwined with the document contents, rather it's contained in a separate file or separate part of the document itself. Files containing metadata can be attached to XHTML documents by using the <link> element in the head of the document. The properties rel, about, and href allow reference to resources inside or outside the document [REF-6]."
