Resource Description Framework
<World-Wide Web, specification, data> (RDF) A specification being developed in 2000 by the W3C as a foundation for processing meta-data regarding resources on the Internet, including the World-Wide Web. Resource Description Framework data consists of resources (nodes), and property/value pairs describing the resource. A node is any object which can be pointed to by a URI, properties are attributes of the node, and values can be either atomic values for the attribute, or other nodes. For example, information about a particular web page (a node), might include the property "Author". The value for the Author property could be either a string giving the name of the author, or a link to a resource describing the author. Resource Description Framework only specifies a mechanism for encoding and transferring meta-data. It does not specify what that meta-data should, or can be. RDF does not, for example, define an "Author" attribute. Sets of properties are defined within RDF Vocabularies (or Schemas). Anynone can create an RDF schema, describing a specialized set of properties, by creating a resource, referenced by the Schema URI, which provides a human- and machine-understandable definition of the schema's properties. The description of a node may include properties defined in different schemas. The properties within a resource description are associated with a certain schema definition using the XML namespace mechanism. Schemas currently being developed include a content screening system modeled after PICS, and a bibliographic vocabulary, such as the Dublin Core Initiative. Home.

Resource Description Framework (RDF)
a framework for metadata and provides for interoperability for applications in "machine-understandable" information on the Web. RDF draws upon several technologies such as XML (Extensible Markup Language). RDF a recommendation of the World Wide Web Consortium currently headed by Tim Bermers-Lee, the creater of the HTML markup language and the http protocol that is the basis of the World Wide Web. Over the long run, Berners-Lee envisions a time when Web sites can be devoid of most broken links and difficult-to-find information. The first step to understanding RDF is to distinguish between data and metadata. Metadata tags in documents and databases provide "data about data" like unseen genes provide data about body parts. One of the drawbacks of HTML is that HTML tags relate only symbols rather than attributes of what the symbols depict. For example, HTML tags tell us how to display the word "eyes" in a web document but there are no tags related to attributes such as eye color, eye size, vision quality, and susceptibility to various eye diseases.

Resource Description Framework
The World Wide Web was originally built for human consumption, and although everything on it is machine-readable, this data is not machine-understandable. It is very hard to automate anything on the Web, and because of the volume of information the Web contains, it is not possible to manage it manually. The solution proposed here is to use metadata to describe the data contained on the Web. Metadata is"data about data" (for example, a library catalog is metadata, since it describes publications) or specifically in the context of this specification"data describing Web resources". The distinction between"data" and"metadata" is not an absolute one; it is a distinction created primarily by a particular application, and many times the same resource will be interpreted in both ways simultaneously.
Resource Description Framework (RDF) is a foundation for processing metadata; it provides interoperability between applications that exchange machine-understandable information on the Web. RDF emphasizes facilities to enable automated processing of Web resources. RDF can be used in a variety of application areas; for example: in resource discovery to provide better search engine capabilities, in cataloging for describing the content and content relationships available at a particular Web site, page, or digital library, by intelligent software agents to facilitate knowledge sharing and exchange, in content rating, in describing collections of pages that represent a single logical"document", for describing intellectual property rights of Web pages, and for expressing the privacy preferences of a user as well as the privacy policies of a Web site. RDF with digital signatures will be key to building the"Web of Trust" for electronic commerce, collaboration, and other applications.

Resource Description Framework
Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata model but which has come to be used as a general method of modeling information, through a variety of syntax formats.
The RDF metadata model is based upon the idea of making statements about resources in the form of subject-predicate-object expressions, called triples in RDF terminology. The subject denotes the resource, and the predicate denotes traits or aspects of the resource and expresses a relationship between the subject and the object. For example, one way to represent the notion "The sky has the color blue" in RDF is as a triple of specially formatted strings: a subject denoting "the sky", a predicate denoting "has the color", and an object denoting "blue".
