RDA: Resource Description and Access : il nuovo standard per la metadatazione e la scoperta delle risorse nell'era digitale

This work is designed for four kind of readers: cataloguing students, aspirant librarians, librarians who wish to keep up-to-date and anyone who wishes to describe and give access to any kind of resource on the web. Last kind is original but important, because it is expressive of the great change that RDA (Resource Description and Access) is going to promote. In fact, guidelines – rather than rules – are addressed to anyone wishes to describe and make accessible a cultural heritage collection or tout court a collection: librarians, archivists, curators and professionals in any other branch of knowledge. The work is organized in two parts: the former contains theoretical foundations of cataloguing (FRBR, ICP, semantic web and linked data), the latter a critical presentation of RDA guidelines. RDA aims to make possible creation of well-structured metadata for any kind of resources, reusable in any context and technological environment. RDA offers a “set of guidelines and instructions to create data for discovery of resources”. Guidelines stress four actions – to identify, to relate (from FRBR/FRAD user tasks and ICP), to represent and to discover – and a noun: resource. To identify entities of Group 1 and Group 2 of FRBR (Work, Expression, Manifestation, Item, Person, Family, Corporate Body); to relate entities of Group 1 and Group 2 of FRBR, by means of relationships. To enable users to represent and discover entities of Group 1 and Group 2 by means of their attributes and relationships. These last two actions are the reason of users’ searches, and users are the pinpoint of the process. RDA enables the discovery of recorded knowledge, that is any resource conveying information, any resources transmitting intellectual or artistic content by means of any kind of carrier and media. RDA is a content standard, not a display standard nor an encoding standard: it gives instructions to identify data and does not care about how display or encode data produced by guidelines. RDA requires an original approach, a metanoia, a deep change in the way we think about cataloguing. Innovations in RDA are many: it promotes interoperability between catalogs and other search tools, it adopts terminology and concepts of the Semantic Web, it is a global standard, it can be applied by different agencies to create data. RDA is expected to be enriched by wide community of professional, from all the world, in a collaborative, well-aware, recognized and global perspective. By RDA, the great tradition of cataloguing goes one step further and enters in the digital age definitively
