How recent approaches to metadata is improving the web

This talk will focus on recent approaches to enriched content, like microformats, microdata, schema.org, RDFa, etc. As heavy semantic web technologies has not yet reached general acceptance in practice, it is interesting to see how more light-weight approaches are being adopted. These kinds of simpler approaches are suitable for a wide range of concrete needs. The technologies have been defined to preserve overall content structure, to enrich specific pieces of content, to be rendered in browsers in predictable ways, and to enable more intelligent processing by web tools and plugins that understand these embedded light-weight annotations of content. The presentation will characterise some of these formats for enriched contents, and how they are intended to be used. And what kinds of business value is created by the use of such metadata approaches.
