Title

Web der Zukunft : RDF - Der erste Schritt zum semantischen Web

Source

XML Magazin und Web Services. 2003, H.1, S.40-43

Abstract

Seit dem 22. Februar 1999 ist das Resource Description Framework (RDF) als W3C-Empfehlung verfügbar. Doch was steckt hinter diesem Standard, der das Zeitalter des Semantischen Webs einläuten soll? Was RDF bedeutet, wozu man es einsetzt, welche Vorteile es gegenüber XML hat und wie man RDF anwendet, soll in diesem Artikel erläutert werden.
