Resource Description Framework, or RDF, is an attempt to improve negotiation of the Internet. It is intended to help people find their way around in the same way that a library labeling system helps you find books. The library can be compared to a really, really big library. In the same way that a library book code will have different fields, an RDF has three parts: resource, property and value.

RDF Labeling System

RDF is a framework for describing and interchanging metadata. A resource would be anything that can have a URL. A property is a resource that has a name and can be used as a property. A statement consists of a resource, a property and a value.

RDF and XML

RDF statements can be converted into XML so they are easily used in today's web environment. Properties, values and statements can all be resources. XML is an essential part of RDF's scalability and interchangeability. Together they can provide a really effective solution for navigation of the web.

RDF provides a model for the processing of metadata, together with a syntax so that independent parties can use it. It doesn't, however, provide any properties of its own. It also doesn't define the resource, the property, the statement or the value. This job is for the coders. It is unlikely, of course, that even a large proportion of the entities on the Internet will end up using RDF, but the concept is so good, that even if only a proportion of them do, it will go some of the way towards improving negotiation of the Information Highway.
