Argot

argot-hub http://code.google.com/p/argot-hub/ is the home of a collection of vocabularies or word-bundles (an argot), that can be used to describe data. The range of argots is wide, and they can either be used on their own, or with others.

Getting Started Embedded Html http://code.google.com/p/argot-hub/wiki/GettingStartedEmbeddedHtml provides an introduction to embedding Argots as RDFa within your HTML and XHTML pages.
