    Abstract
    Die OWL Web Ontology Language wurde entwickelt, um es Anwendungen zu ermöglichen den Inhalt von Informationen zu verarbeiten anstatt die Informationen dem Anwender nur zu präsentieren. OWL erleichtert durch zusätzliches Vokabular in Verbindung mit formaler Semantik stärkere Interpretationsmöglichkeiten von Web Inhalten als dies XML, RDF und RDFS ermöglichen. OWL besteht aus drei Untersprachen mit steigender Ausdrucksmächtigkeit: OWL Lite, OWL DL and OWL Full. Dieses Dokument wurde für Leser erstellt, die einen ersten Eindruck von den Möglichkeiten bekommen möchten, die OWL bietet. Es stellt eine Einführung in OWL anhand der Beschreibung der Merkmale der drei Untersprachen von OWL dar. Kenntnisse von RDF Schema sind hilfreich für das Verständnis, aber nicht unbedingt erforderlich. Nach der Lektüre dieses Dokuments können sich interessierte Leser für detailliertere Beschreibungen und ausführliche Beispiele der Merkmale von OWL dem OWL Guide zuwenden. Die normative formale Definition von OWL findet sich unter OWL Semantics and Abstract Syntax.

    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.

    Content
    RDF Data Model At the core of RDF is a model for representing named properties and their values. These properties serve both to represent attributes of resources (and in this sense correspond to usual attribute-value-pairs) and to represent relationships between resources. The RDF data model is a syntax-independent way of representing RDF statements. RDF statements that are syntactically very different could mean the same thing. This concept of equivalence in meaning is very important when performing queries, aggregation and a number of other tasks at which RDF is aimed. The equivalence is defined in a clean machine understandable way. Two pieces of RDF are equivalent if and only if their corresponding data model representations are the same. Table of contents 1.
