Semantic Web Crawling: A Sitemap Extention Abstract This document describes an extension to the Sitemap protocol targeted at the efficient discovery and use of RDF data. The extension allows Data publishers to state where documents containing RDF data are located, and to advertise alternative means to access it, such as data dumps and SPARQL endpoints.
Quand la donnée prend le dessus. C’est ainsi que pourrait être, très vulgairement, résumé le Web sémantique. Un vaste projet qui a éclaté aux yeux de tous suite à l‘intervention de Tim Berners-Lee, patron du W3C - et également père du Web -, le consortium en charge de définir les standards du Web.

Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. More specifically, Wikipedia defines Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF." This site exists to provide a home for, or pointers to, resources from across the Linked Data community.

The RDF book mashup demonstrates how Web 2.0 data sources like Amazon, Google or Yahoo can be integrated into the Semantic Web. The RDF book mashup makes information about books, their authors, reviews, and online bookstores available on the Semantic Web. This information can be used by RDF tools and you can link to it from your own Semantic Web data. Contents News 2009/07/17: GoodRelations support added. RDF Book Mashup

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs, by following rdfs:seeAlso links, and by querying the Sindice search engine. The library is written in Java and is based on the Jena framework. Contents Semantic Web Client Library

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. This version:
Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed.
Notation3 (N3): A readable RDF syntax Up to Design Issues An RDF language for the Semantic Web This article gives an operational semantics for Notation3 (N3) and some RDF properties for expressing logic. These properties, together with N3's extensions of RDF to include variables and nested graphs, allow N3 to be used to express rules in a web environment.
Resource Description Framework (RDF) Schema Specification 1.0 W3C Candidate Recommendation 27 March 2000 This Version: http://www.w3.org/TR/2000/CR-rdf-schema-20000327 Latest Version: http://www.w3.org/TR/rdf-schema Previous Version:
[translations into other languages ] The world of the semantic web, as based on RDF, is really simple at the base. This article shows you how to get started. It uses a simplified teaching language -- Notation 3 or N3 -- which is basically equivalent to RDF in its XML syntax, but easier to scribble when getting started.

RDF Automation Ushering in Semantic Web Researchers with the Rensselaer Polytechnic Institute (RPI) have thrown themselves head over heels into the semantic web. At this year's 8th International Semantic Web Conference, they presented a paper (download the PDF) focused on the problem of automatically generating the metadata that many semantic web functionalities rely on. Talking about RDF closures can cause eyelids to flutter, but the RPI folks aren't living in some theoretical world. They've been digging hard into large, public data sets and have learned some important lessons about making data more useful. Come join us for a closer look.
SWSE - Mission Statement Prototype You can now try out the SWSE prototype. Motivation Although the Semantic Web (SW) is still very much in its infancy, there is already a lot of data out there which conforms to the proposed SW standards (e.g. SWSE
