Abstract

This document specifies usage scenarios, goals and requirements for a web ontology language. An ontology formally defines a common set of terms that are used to describe and represent a domain. Ontologies can be used by automated tools to power advanced services such as more accurate web search, intelligent software agents and knowledge management.

Abstract

RDF - the Resource Description Framework - is a foundation for processing metadata; it provides interoperability between applications that exchange machine-understandable information on the Web. RDF emphasizes facilities to enable automated processing of Web resources. RDF metadata can be used in a variety of application areas; for example: in resource discovery to provide better search engine capabilities; in cataloging for describing the content and content relationships available at a particular Web site, page, or digital library; by intelligent software agents to facilitate knowledge sharing and exchange; in content rating; in describing collections of pages that represent a single logical "document"; for describing intellectual property rights of Web pages, and in many others. RDF with digital signatures will be key to building the "Web of Trust" for electronic commerce, collaboration, and other applications. Metadata is "data about data" or specifically in the context of RDF "data describing web resources." The distinction between "data" and "metadata" is not an absolute one; it is a distinction created primarily by a particular application. Many times the same resource will be interpreted in both ways simultaneously. RDF encourages this view by using XML as the encoding syntax for the metadata. The resources being described by RDF are, in general, anything that can be named via a URI. The broad goal of RDF is to define a mechanism for describing resources that makes no assumptions about a particular application domain, nor defines the semantics of any application domain. The definition of the mechanism should be domain neutral, yet the mechanism should be suitable for describing information about any domain. This document introduces a model for representing RDF metadata and one syntax for expressing and transporting this metadata in a manner that maximizes the interoperability of independently developed web servers and clients. The syntax described in this document is best considered as a "serialization syntax" for the underlying RDF representation model. The serialization syntax is XML, XML being the W3C's work-in-progress to define a richer Web syntax for a variety of applications. RDF and XML are complementary; there will be alternate ways to represent the same RDF data model, some more suitable for direct human authoring. Future work may lead to including such alternatives in this document.

Abstract

Am 12. Dezember 2017 ist das neue Release des RDA Toolkits erschienen. Dabei gab es, aufgrund des 3R-Projekts (RDA Toolkit Restruction and Redesign Project), keine inhaltlichen Änderungen am RDA-Text. Es wurden ausschließlich die Übersetzungen in finnischer und französischer Sprache, ebenso wie die dazugehörigen Policy statements, aktualisiert. Für den deutschsprachigen Raum wurden in der Übersetzung zwei Beziehungskennzeichnungen geändert: Im Anhang I.2.2 wurde die Änderung von "Sponsor" zu "Träger" wieder rückgängig gemacht. In Anhang K.2.3 wurde "Sponsor" zu "Person als Sponsor" geändert. Außerdem wurde die Übersetzung der Anwendungsrichtlinien (D-A-CH AWR) ins Französische aktualisiert. Dies ist das vorletzte Release vor dem Rollout des neuen Toolkits. Das letzte Release im Januar/Februar 2018 wird die norwegische Übersetzung enthalten. Im Juni 2018 wird das RDA Toolkit ein Relaunch erfahren und mit einer neuen Oberfläche erscheinen. Dieser beinhaltet ein Redesign der Toolkit-Oberfläche und die inhaltliche Anpassung des Standards RDA an das Library Reference Model (IFLA LRM) sowie die künftige stärkere Ausrichtung auf die aktuellen technischen Möglichkeiten. Zunächst wird im Juni 2018 die englische Originalausgabe der RDA in der neuen Form erscheinen. Alle Übersetzungen werden in einer Übergangszeit angepasst. Hierfür wird die alte Version des RDA Toolkit für ein weiteres Jahr zur Verfügung gestellt. Der Stand Dezember 2017 der deutschen Ausgabe und die D-A-CH-Anwendungsrichtlinien bleiben bis zur Anpassung eingefroren. Nähere Information zum Rollout finden Sie unter dem folgenden Link<http://www.rdatoolkit.org/3Rproject/SR3>. [Inetbib vom 13.12.2017]
