On June 2, the big three search engines (Google, Yahoo, and Bing) announced Schema.org, which helps them show search results in a more useful way. The announcement has gotten people really interested in inline structured data such as microdata and RDFa.
This screencast shows how you can use the microdata module to place Schema.org terms. This is an early preview—very few field formatters have microdata support at this time and the module is still changing quite a bit—but I thought people might be interested in the direction the module is heading.
