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.W3C Recommendation 15 January 2008 New Version Available: SPARQL 1.1 (Document Status Update, 26 March 2013) The SPARQL Working Group has produced a W3C Recommendation for a new version of SPARQL which adds features to this 2008 version. Please see SPARQL 1.1 Overview for an introduction to SPARQL 1.1 and a guide to the SPARQL 1.1 document set.
SPARQL Query Language for RDF
Abstract 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. Contents
RDF Vocabulary Description Language 1.0: RDF Schema
Abstract The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF, and OWL 2 ontologies themselves are primarily exchanged as RDF documents. This document serves as an introduction to OWL 2 and the various other OWL 2 documents. It describes the syntaxes for OWL 2, the different kinds of semantics, the available profiles (sub-languages), and the relationship between OWL 1 and OWL 2.

RDFa Primer
Abstract GRDDL is a mechanism for G leaning R esource D escriptions from D ialects of L anguages. It is a technique for obtaining RDF data from XML documents and in particular XHTML pages. Authors may explicitly associate documents with transformation algorithms, typically represented in XSLT, using a link element in the head of the document.
GRDDL Primer
Abstract This document is an overview of the Rule Interchange Format (RIF). It provides a high-level explanation of RIF concepts and architecture as well as a general survey of RIF documents. Status of this Document May Be Superseded This section describes the status of this document at the time of its publication.
RIF Overview
RIF In RDF
Abstract Rules interchanged using the Rule Interchange Format RIF may depend on or be used in combination with RDF data and RDF Schema or OWL ontologies. This document, developed by the Rule Interchange Format (RIF) Working Group , specifies the interoperation between RIF and the data and ontology languages RDF, RDF Schema, and OWL.
RIF RDF and OWL Compatibility
Abstract This document shows how OWL 2 RL can be implemented using RIF. It provides an analysis of how to represent OWL 2 RL inference rules within RIF Core. The OWL 2 RL inference rules can be implemented both via a fixed RIF Core rule set (Appendix 7) and via a mapping algorithm which converts an OWL 2 RL ontology to a customized RIF Core rule set (Appendix 8).
