New technologies in the field of Information Science permit institutions to transit to a different role, that of managing and representing knowledge coming from distinct information environments.
New technologies also offer the challenge to reconsider the role of a catalogue and perceive it as a network of interrelated –in a meaningful way- entities and a sophisticate information retrieval tool instead of a simple descriptive list of objects.
Furthermore new technologies dedicate attention to the semantics by making explicit the semantics behind the data and make their content understandable by machines and interoperable with different information systems
They facilitate integrated view also by helping to achieve syntactic interoperability through the Resource Description Framework (RDF) the most common language for knowledge exchange on the Semantic Web. By expressing data as RDF statements it is getting much easier to incorporate them in the Semantic Web or relate them to ontologies
Last but not least, new technologies in Information Science have contributed to the development of automated tools for mapping among different metadata structures. A common conceptual basis would essentially facilitate automated mapping tasks.
