When a computer scans a Web page, it can distinguish words on the page, but it doesn’t have a way to attach meaning to those words. A Resource Description Framework file provides contextual information about the data contained on a Web page by using specific XML tags. For example, an RDF file for a Web page that lists clothing for sale might identify each item as an article of clothing, specify the type of clothing and identify attributes such as a specific number that represents size and a specific word that represents color.
