Linked Data views of information about titles, batches, issues, and pages in RDF/XML.

Managing News is both a product and a platform. Out of the box it can help your communications team manage a brand reputation, allow geographically dispersed clusters of NGOs stay on the same page, or act as a simple thematic news planet to share feeds with the world. It can also serve as a platform to build highly custom data aggregators that suck in everything from CSV to RDF to custom XML formats and that need unique workflows and visualizations. Managing News is built on Drupal and uses Features, which makes it highly extensible.

Why is it good? Because we’ll learn a few tricks about how to do stuff with just JavaScript and no yucky backend stuff like PHP.

Way back in 2006 I wrote a blog post concerning the modelling of time in RDF (see Refactoring Bio With Einstein Part 3: Temporal Invariants. That post also provoked some discussion in the blogosphere. Although I haven’t written anything on the subject for the past three years I haven’t stopped thinking about it. In fact I’ve been working quite hard on the problem, mainly by modelling real data, especially geographical information. This is the first of a series of blog posts describing my experiments. I’d like to thank Leigh Dodds and Jeni Tennison who gave me valuable feedback on an earlier version of this write-up.

Summary: As more data is being stored in RDF formats like RSS, a need has arisen for a simple way to locate specific information. SPARQL, a powerful new query language fills that space, making it easy to find the data you need in the RDF haystack. Take a tour of SPARQL's features and learn how to use SPARQL queries from your own Java™ applications with the Jena Semantic Web Toolkit.

Mais en RDF, contrairement à XML, chaque triplet est indépendant et signifiant indépendamment de tout contexte, ce qui signifie que je peux tout à fait utiliser pour décrire la même ressource des propriétés du Dublin Core et d'autres propriétés, venant d'autres vocabulaires ou ontologies.

I tested it a bit, and it seems that what's implemented in that tool bears very little relation to RDFa. It's not simply a buggy implementation - it's not even attempting to handle RDFa remotely correctly.

Comme d'habitude, Google et ses milliers de docteurs en sciences est infichu d'appliquer un standard, si minime soit-il, du premier coup. Il faut dire que les docteurs en sciences chez Google sont tous dans les département "datamining" et "publicité". A la programmation, ils n'ont laissé que les prag-ma-ti-ques.

The New York Times includes a large amount of topical metadata with each article it publishes. These daily dumps plot the relationships, and geographies, of each article and are archived as RDF, XHTML and SVG maps.

OpenVocab is ideal for properties and classes that don't warrant the effort of creating or maintaining a full schema. OpenVocab allows anyone to create and modify vocabulary terms using their web browser. Each term is described using appropriate elements of RDF, RDFS and OWL. OpenVocab allows you to create any properties and classes; assign labels, comments and descriptions; declare domains and ranges and much more.

I have written a wrapper to expose openlibrary.org api data as RDF. It is written in Python and deployed on Google App Engine. It is only an illustration of Linked Data publication, and in order to get a first feedback, so do not rely on it in your application since the URL or the content will change in the future.

Les RDF Men présentent leur nouveau champion : Manu Sporny. Pour une nouvelle réécriture des Textes Sacrés : plus d'éditeurs, plus de spécialistes, plus d'accessibilité, plus de modularité, plus d'attention envers les orphelins (RDFa).

Il semble que Manu soit de très bonne famille et œcuménique par dessus ça : il est éditeur de vocabulaires RDF et microformat.

4store was designed by Steve Harris and developed at Garlik to underpin their Semantic Web applications. It has been providing the base platform for around 3 years. At times holding and running queries over databases of 15GT, supporting a Web application used by thousands of people.

The non-RDF bits of the data Web are – roughly – going to be the leaves on the tree.
