RDA and SemanticWeb: machine-readable RDA's elements with RDF

Today more information resources are published in electronic and digital formats and they are available on the web. The production, distribution and storage of information are easily possible on the Web but theie retrieval is a challenge to the user. Researchers in various fields, including library and Web designer’s communities, are thinking about the solutions to solve these problems. Developing the Resource Description and Access (RDA) by the Joint Steering Committee as a successor of the Anglo-American Cataloguing Rules, Second Edition, base on conceptual models and International cataloging rules developed by the IFLA and the emergence of the Semantic Web and its models, including Resource Description Framework (RDF) by The World Wide Web Consortium are examples of solutions to provide efficient description of information resources and present the conceptual relationship between them on the web environment. This study attempts to make librarians and catalogers familiar with RDA, Semantic web and RDF, one of the standards of semantic web. It also attempts to adapt entities and vocabularies of RDA in RDF that was based on cooperation between the Joint Steering Committee and the Dublin Core Metadata Initiative. In the end the eXtensible Catalog which has been designed based on RDA, FRBR and RDF is introduced. Also, the basic attention to the underlying structure and models of RDA and similarities that this standard has with RDF in information storage and retrieval for increasing functionality of information retrieval systems have been analyzed.
