Semantic Web | Resource Description Framework

Resource Description Framework (RDF)

What is the Semantic Web?

The Semantic Web is focused on machines. The Web requires a human operator, using computer systems to perform the tasks required to find, search and aggregate its information. It's impossible for a computer to do these tasks without human guidance because Web pages are specifically designed for human readers. The Semantic Web aims to change Web page data in such a way that it is understood by computers. Thus, enabling machines to do the searching, aggregating and combining of the Web's information without a human operator.

Short for Resource Description Framework, RDF is a general framework for describing a Web site's metadata or the information about the information on the site. It provides interoperability among applications that exchange machine information on the Web. Developed under the guidance of the World Wide Web Consortium, RDF was designed to allow developers to build search engines that rely on the metadata and to allow Internet users to share Web site information more readily.

The Semantic Web is not a separate entity from the World Wide Web. It is an extension to the Web that adds new data and metadata to existing Web documents. It extends those documents into data. This extension of Web documents to data is what will enable the Web to be processed automatically by machines and also manually by humans. To do this RDF (Resource Description Framework) is used to turn basic Web data into structured data that software can make use of. RDF works on Web pages and also inside applications and databases.

Who Uses Semantic Web Technology? It has taken years to put the pieces together that comprise the Semantic Web, including the standardization of RDF, the W3C release of the Web Ontology Language (OWL), and standardization on SPARQL, which adds querying capabilities to RDF.

In Short the key to understanding the Semantic Web: Semantic Web - An extension of the current Web that provides an easier way to find, share, reuse and combine information more easily. RDF - Short for Resource Description Framework. RDF is a general framework for describing a Web site's metadata, or the information about the information on the site.
