Metadata, specifically DCMI (Dublin Core Metadata Initiative) and its element set ISO 15836-2003, establishes one of the operational infrastructures of the Semantic Web and one of the interoperability main keys for electronic information management and retrieval. This metadata schemas, beside XML/RDF syntactic code, the content description schemes (ontologies, topic maps, thesaurus, etc.) and a set of protocols for information interchange, will be the protagonists of the Second Generation of the Web. This landscape will be reflected by this tutorial. Its specific aims are: To present an introduction to the metadata concept and application. To define the metadata role in Web systems and services, versus its role in global information retrieval by all the web search engines.
