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.

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]."
Cheers,
Michael
