Integrating Metadata with the Desktop

There is an interesting article over at the The Useful Information Company describing ways in which the integration of metadata with the desktop may be an inevitable and useful direction. The author argues that as the amount of information stored on desktops rapidly grows, new and innovative ways must be used to locate and interact with that data (down with inefficient hierarchical trees!). As a solution, he suggests using RDF as a potential model. Along with describing the problem, the article also provides links to some nifty RDF toolkits. Here is the Slashdot discussion on the article.
