OWL 2 Web Ontology Language Document Overview
by Xavier LacotThe W3C published 2 days ago the OWL2 Recommendation, made by 12 documents. A great step further in SW technologies, 5 years after the first OWL Recommendation !

Falcon-AO, a prominent component of Falcon, is an automatic ontology matching system that helps actualize interoperability between (Semantic) Web applications that use different but related ontologies. Recently, it has become a very practical and popular choice for matching Web ontologies expressed by RDF(S) and OWL. Falcon-AO is implemented in Java, and presently, it is an open source project under the Apache 2.0 license.
MWSAF(METEOR-S Web Service Annotation Framework) is a semantic web based graphical tool that enables you to annotate existing Web service descriptions with Ontologies. It facilitates the parsing of WSDL files and Ontologies. This enables the user to annotate Web service descriptions semi-automatically.
The Web of Data has many equivalent URIs.
This service helps you to find co-references between different data sets.

Vocabulaire RDF pour les évaluations. Il semble que Google ait choisi de réinventer un autre vocabulaire pour sa fonctionnalité Rich Snippets.
en quoi les technologies du Web sémantique constituent des réponses à certaines limites du modèle des bases de données relationnelles et donc en quoi elles peuvent avoir leur place dans les systèmes d'information traditionnelles
D2RQ is a declarative language to describe mappings between relational database schemata and OWL/RDFS ontologies. The D2RQ Platform uses these mapping to enables applications to access a RDF-view on a non-RDF database through the Jena and Sesame APIs, as well as over the Web via the SPARQL Protocol and as Linked Data.
Knoodl facilitates community-oriented development of OWL based ontologies and RDF knowledgebases.

SWOOP is a tool for creating, editing, and debugging OWL ontologies. It was produced by the MIND lab at University of Maryland, College Park, but is now an open source project with contributers from all over.
Le moteur d’inférence qui va rajouter des nouvelles informations à partir des informations existantes est le composant pour lequel il n’y a pas d’équivalent dans le monde SGBD (1); c’est lui qui vient donner tout son sens au reste de la pyramide des technos (XML, URI, RDF, OWL), en interprétant et “motorisant” une ontologie.
OwlSight is an OWL ontology browser that runs in any modern web browser; it's developed with Google Web Toolkit and uses Gwt-Ext, as well as OWL-API. OwlSight is the client component and uses Pellet as its OWL reasoner.

Ever have wondered if there is something around like a command line for the Semantic Web? An online tool that allows you load and query a range of data sources? Well, peradventure Benjamin Nowack has developed a tool, called SPARQLBot, that does all this
An ontology that describes tags, as used in the popular del.icio.us and Flickr systems, and allows for relationships between tags to be described.

An ontology to describe an Exif format picture data. All Exif 2.2 tags are defined as OWL properties (annotated by 'exif:exifNumber' in this vocabulary), as well as several terms to help this schema.

Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).
