"In acknowledging the Web as the platform for searching, sharing, aggregating and extending information, librarians need to familiarize themselves with the semantic web (an extension of the current web), learn new tools, techniques and trends. Most importantly for catalogers, they need to educate themselves in RDA (Resource Description and Access) which may soon replace AACR2 and MARC 21 as the new cataloging rules and standards. RDA is a set of guidelines evolved from AACR2 and is constructed on the framework of FRBR (Functional Requirements for Bibliographic Records) and FRAD (Functional Requirements of Authority Data). The application of which is meant to direct the library catalog in providing better access to Web resources. Instead of being a display standard of library catalog using AACR2, RDA is a content standard that attempts to improve the way catalogers describe and present elements, entities and their relationships and roles in the bibliographic world. It is also the intention of RDA to make data in library catalog play a better role in the Web environment. Moreover, RDA is supposedly more flexible and adaptable in that it may be used with many encoding schema such as MODS, MARC, Dublin Core, etc."

"RDA sera peut-être le format de catalogage de demain. Basé sur les FRBR et les FRAR, RDA se donne les objectifs suivants : * Fournir un "framework" fiable et souple pour décrire à la fois le contenu et les aspects techniques de tous types de ressources et de documents * Etre compatible avec des principes, modèles et standards internationaux * Etre utilisable hors de la communauté des bibliothèques, et que des communautés variées puissent l'adapter à leurs besoins spécifiques. "

"Resource Description and Access (RDA) est le code de catalogage qui remplacera en 2010 les Règles de catalogage anglo-américaines, 2e éd. (AACR2). "

"Library data has been designed to be read and interpreted by librarians and users. Although there are some controlled data fields, most of what is in the library catalog entry is text. The machine as user has not gotten a great deal of attention in the library cataloging environment. Now there's yet another potential user of library data, and that user is the Web and services that function on the Web. (...) This issue of Library Technology Reports provides an explanation, using concrete models and real-world examples, of how to facilitate this transformation."
