Explanation : Resource Description Framework. A specification being developed by the W3C to provide an infrastructure to support metadata on the Internet and WWW. For example, using RDF, data about a Web page could be divided into a main subject, secondary subjects, date of creation, name of author, etc. Putting this data into fields (which can be indicated by XML tags) would allow search engines to do smarter searches. A search engine could find, for example, all documents written by a particular author before a given date, on a specific subject. RDF does not specify names for the fields, but defines the syntax for how different fields relate to Web pages and to one another. Other examples of how RDF could be used include sitemaps, content ratings, digital libraries, and distributed authoring. |
