Listing Examples

This is an exploratory page to document listing (e.g. For Sale, Wanted) examples currently published around the web. Typically, the metadata associated with this content is stored in non-semantic markup and proprietary feed formats. The purpose of the studies on this page is to serve as background for the design of a simple distributed listings microformat.
