Resource Description Framework (RDF)

Resrource Description Framework (RDF) is opgesteld door de World wide web consortium (W3C). Deze is ontworpen als een metadata data model. Het wordt gebruikt als een conceptuele beschrijving of modelering dat geimplementeeerd is in web resources.

De specificaties zijn als volgt:
• rdf:type - an instance of rdf:Property used to state that a resource is an instance of a class
• rdf:first - the first item in the subject RDF list
• rdf:rest - the rest of the subject RDF list after rdf:first
• rdf:value - idiomatic property used for structured values
• rdf:subject - the subject of the subject RDF statement
• rdf:predicate - the predicate of the subject RDF statement
• rdf:object - the object of the subject RDF statement

RDF Schema 1.1
The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This specification describes how to use RDF to describe RDF vocabularies. This specification defines a vocabulary for this purpose and defines other built-in RDF vocabulary initially specified in the RDF Model and Syntax Specification.

RDF 1.1 XML Syntax
The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web.
This document defines an XML syntax for RDF called RDF/XML in terms of Namespaces in XML, the XML Information Set and XML Base. The formal grammar for the syntax is annotated with actions generating triples of the RDF graph as defined in RDF Concepts and Abstract Syntax. The triples are written using the N-Triples RDF graph serializing format which enables more precise recording of the mapping in a machine processable form. The mappings are recorded as tests cases, gathered and published in RDF Test Cases.

RDF 1.1 Concepts and Abstract Syntax
The Resource Description Framework (RDF) is a framework for representing information in the Web. RDF 1.1 Concepts and Abstract Syntax defines an abstract syntax (a data model) which serves to link all RDF-based languages and specifications. The abstract syntax has two key data structures: RDF graphs are sets of subject-predicate-object triples, where the elements may be IRIs, blank nodes, or datatyped literals. They are used to express descriptions of resources. RDF datasets are used to organize collections of RDF graphs, and comprise a default graph and zero or more named graphs. This document also introduces key concepts and terminology, and discusses datatyping and the handling of fragment identifiers in IRIs within RDF graphs.

Internationalization Tag Set (ITS) Version 2.0
This document defines data categories and their implementation as a set of elements and attributes called the Internationalization Tag Set (ITS) 2.0. ITS 2.0 is the successor of ITS 1.0; it is designed to foster the creation of multilingual Web content, focusing on HTML5, XML based formats in general, and to leverage localization workflows based on the XML Localization Interchange File Format (XLIFF). In addition to HTML5 and XML, algorithms to convert ITS attributes to RDFa and NIF are provided.

Resource Description Framework (RDF): Concepts and Abstract Syntax
The Resource Description Framework (RDF) is a framework for representing information in the Web.
RDF Concepts and Abstract Syntax defines an abstract syntax on which RDF is based, and which serves to link its concrete syntax to its formal semantics. It also includes discussion of design goals, key concepts, datatyping, character normalization and handling of URI references.

RDF Primer
The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents.
