Semantic web Technologies for Digital Libraries From Libraries To Social Semantic Digital Libraries Over Semantic Digital Libraries
Then became a valuable invention that made internet accessible and more convenient to its users- this was the ‘Web’. It was in invented in 1989 by a graduate of Oxford University, England. his name was Tim-Berners Lee. He was responsible for writing the first web client and server in 1990 at CERN (which is the European Particle Physics Laboratory). His vision was to design an internet-based hypermedia system that would facilitate the uploading of information from all corners of the globe so that everyone can benefit from that knowledge . The later developments in the web witnessed the evolution of ‘Semantic Web’. It was still derived from the vision of Tim-Berners Lee of making information global and universal for its users.
Semantic Web extends the meaning (semantic) of information by enabling the web to comprehend the demands of the user and computers so that they can utilize the web for information . Semantic Web is based on a set of design principles and the concept of providing useful results to the user . Web offered services and information that could be comprehended by humans only, but semantic web is able to produce information in a manner that can be understood by computers also . Some of the main technologies of Semantic Web are:
Resource Description Framework (RFD) was initially implemented as a metadata data model. With the passage of the years, it has evolved into a mode of conceptual description and a mechanism to provide more meaning to information on the web , . Ontology can be described as the method of representing information in a formal and structured manner by the help of a set of concepts and their respective relationships. Web Ontology Language (OWL) is described as the set of information modeling languages that can be used to produce ontologies , , . Ontologies play an important role to cope with the structural differences
