Search engines in the Web more and more exploit and evaluate embedded semantic code (i.e. RDFa tags) in web pages. In fact it is the idea of "semantic" in the web 2.0 which today plays the role which XML played 10 years ago in the evolving internet.

As long as an end user would have to deal with expert tools like Protégé in order to craft semantic models semantic modelling will not become accessible to a broader publicum.

However, currently there are evolving more and more integrated tools to bring together ordinary, more "informal" text authoring and advanced, more "semantic" knowledge modelling. This makes semantic modelling attractive even to (analytically thinking) end users who are not trained ontology engineers.
