GRDDL glaner des descriptions de ressources dans les dialectes des langages
Voici la traduction française complète du tutoriel How to Publish Linked Data on the Web publié par Chris Bizer (Web-based Systems Group, Freie Universität Berlin, Germany), Richard Cyganiak (Web-based Systems Group, Freie Universität Berlin, Germany) et Tom Heath (Knowledge Media Institute, The Open University, Milton Keynes, UK). Ce document explique la façon de publier des données liées sur le Web. Après un aperçu général de la notion de données liées, plusieurs recettes pratiques sont présentées pour la publication d’information sous forme de données liées sur le Web. la section 4 examine des termes bien connus de vocabulaires et de sources de données qui devraient être réutilisé pour représenter de l’information, la section 5 explique quelles informations doivent être incluses dans les descriptions RDF qui sont publiés sur le Web,
Comment faire pour publier données liées sur le Web?
Raptor RDF Parser Toolkit for Redland
Raptor is a free software / Open Source C library that provides a set of parsers and serializers that generate Resource Description Framework (RDF) triples by parsing syntaxes or serialize the triples into a syntax. The supported parsing syntaxes are RDF/XML, N-Quads, N-Triples, TRiG, Turtle, RSS tag soup including all versions of RSS, Atom 1.0 and 0.3, GRDDL and microformats for HTML, XHTML and XML and RDFa. The serializing syntaxes are RDF/XML (regular, and abbreviated), Atom 1.0, GraphViz, JSON, N-Quads, N-Triples, RSS 1.0 and XMP. Raptor was designed to work closely with the Redland RDF library ( R DF P arser T oolkit f o r R edland) but is entirely separate. It is a portable library that works across many POSIX systems (Unix, GNU/Linux, BSDs, OSX, cygwin, win32). A summary of the changes can be found in the NEWS file, detailed API changes in the release notes and file-by-file changes in the ChangeLog .RDF and RDFS Editing
Altova SemanticWorks® 2012 provides powerful support for designing and editing RDF and RDFS documents to implement Semantic Web applications in an intuitive, visual manner. RDF (Resource Description Framework) is an XML-based standard for describing resources that exist on the Web, intranets, and extranets. RDF builds on existing XML and URI (Uniform Resource Identifier) technologies, using a URI to identify every resource, and using URIs to make statements about resources. RDF statements describe a resource, the resource’s properties, and the values of those properties and are often referred to as “triples.” RDF triples consist of a subject, predicate, and object, which correspond to a resource (subject), property (predicate), and property value (object).
Global Filters allow a user to hide or view specific edges based on type. For instance, one can hide all edges of "rdf:bag", "dc:author" or a specific type occurring in any particular given ontology.

Support for semi-structural full text search, top-k query, scalability via shard over clusters of commodity machines, efficient caching strategy and real-time dynamic index maintenance. With respect to point 1, the two formats which enable the annotations of entities on web pages are Microformats and RDF. At knowledge representation level, the main difference between Microformats and RDF is that the former can be seen as a frame model while the latter has a graph based data model.

SIREn: Semantic Information Retrieval Engine
SIREn: Efficient semi-structured Information Retrieval for Lucene Efficient, large scale handling of semi-structured data (including RDF ) is increasingly an important issue to many web and enterprise information reuse scenarios. Querying graph structured data (RDF) is commonly achieved using specific solutions, called triplestores , typically based on DBMS backends.Ping the Semantic Web.com - Share your RDF data with the World!

SemanticWebTools - ESW Wiki
This page contains the information on RDF and OWL tools that used to be listed on the home pages of the RDF and OWL Working Groups at W3C. Keeping such lists up-to-date is obviously a problem when the number of Semantic Web tools increases every day. By moving this list to the Wiki, we hope that the community at large will help maintain these pages (see also notes for contributors ).
How... can I use it? Think of a input URI that has some RDF syntax content, or some microformat that Raptor can understand via GRDDL. Remove http:// from the start. OK, I lied. There are also some optional parameters you can give as a Matrix URI right after the output format .
