Resource Description Framework (RDF)
Resource Description Framework (RDF) is a general framework or set of rules for describing any Internet resource, especially information available on the World Wide Web such as a website and it’s content. An RDF description is also referred to as metadata, which can include the all the information of a resource including the author of the resource, the date of creation or update, the organization of the pages on a site, information that describes the content in terms of audience or content rating, keywords that search engines look for and subject categories.
Features of the Resource Description Framework
The Resource Description Framework makes it possible for everyone to share a website and other descriptions more easily. Software developers can use the metadata to provide better search engines and directories.
RDF can also be used to describe a collection of books, or artists, or a collection of web pages as in the RSS data format which uses RDF to create machine-readable summaries of web sites.
RDF is also used in XPFE applications to define the relationships between different collections of elements, for example RDF could be used to define the relationship between the data in a database and the way that data is displayed to a user.
RDF was developed under the guidance of World Wide Web Consortium(W3C) to allow developers to build search engines that rely on the metadata and to allow Internet users to share website information more readily. RDF relies on XML as an interchange syntax, creating an ideal system for the exchange of information on the Web.
