'Designing data for the open world of the web', 'La traduzione dei dati nel linguaggio del web semantico'

Abstract

The domain name system of the world wide web provides a managed space of globally unique identifiers for web pages -- Uniform Resource Identifiers, or URIs. URIs can also be used to name things – specifically, to name things in the world (people, a books, or Nelson Mandela); to name concepts used to describe those things (Renaissance Sculpture or Lyme Disease); and to name relationships between things (this book translated by that person). Because URIs, used as names, are globally unique, they serve to anchor the strands in of meaning (semantic web). Each strand of the web is a statement following a grammar, the Resource Description Framework (RDF), which uses URIs as its words. Each RDF statement expresses a simple idea – Dante wrote L'Inferno or Dante was born in Florence – which, taken together, can express complex webs of relationships. Expressing data as statements makes it easy to integrate data across many different sources (linked data). The opportunity for cultural heritage lies in translating the traditions of resource description into the language of URIs so that its descriptions of Works, Items, Subject Headings, and People can serve as central hubs in growing webs of linked data.
