This is one of several semantic repositories that contains and publishes RDF and co-reference data, forming the underlying distributed storage model behind the RKB Explorer initiative. The data presented here comes from downloading and processing as many OAI archives from around the world as I could manage to harvest using OAI-PMH. The list of archives came from ROAR.

PRISM module for RSS 1.0: Publishing Requirements for Industry Standard Metadata

Dublin Core module for RSS 1.0

pyRdfa is a distiller that generates the RDF triples from an (X)HTML RDFa or SVG Tiny 1.2 file in various RDF serialization formats. It can either be used directly from a command line or via a CGI service.

SIREn - Semantic Information Retrieval Engine - a Lucene plugin to overcome these shortcomings and efficiently index and query RDF, as well as any textual document with an arbitrary amount of metadata fields.

DOAC is a RDF metadata vocabulary to describe professional capabilities of a worker like any curriculum or resume that people use to have in their websites but with much better capabilities. Business people will be able to search the internet to find a worker that fits their requirements and will be as easy as any search in Google.

4store, an efficient, scalable and stable RDF database. Système de gestion de base de données RDF open source pour des grands volumes de données (annonce 15 milliards de triplets !!). Propose un sparql endpoint, une API REST pour ajouter ou enlever des données, un système de backup. Pas de précision sur la façon de supporter les graphes nommés. Pas de support de Jena ou Sesame.

Thèse de doctorat (informatique) d'Alexandre Passant - 9 juin 2009

Anzo includes both an open source enterprise-featured RDF quad store and a sophisticated service oriented, semantic middleware platform that provides support for multiple users, distributed clients, offline work, real-time notification, named-graph modularization, versioning, access controls, and transactions. Developers will discover a host of features we believe are necessary for the creation of sophisticated applications based on W3C semantic technology standards like OWL, RDF and SPARQL.

exai is an open source project to create an artificial intelligence. The approach is to first construct an English dialog system whose initial goals are to acquire linguistic and common sense skills that improves its own performance. The project is hosted at SourceForge and has already released the largest freely available English lexicon in RDF.

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

It’s been great to see RDFa being picked up by web2.0 publishers like Digg and MySpace. You can use the RDFa Distiller to extract the RDFa from a given web page

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.

Une présentation sur le Linked Data

Inspired by Yahoo's Pipes, DERI Web Data Pipes implement a generalization which can also deal with formats such as RDF (RDFa), Microformats and generic XML.

Sesame is an open source framework for storage, inferencing and querying of RDF data.

Create, Read, Update, and Delete (CRUD) operations are the most basic database operations, but they are also the most crucial. CRUD operations are typically done using the Structured Query Language (SQL) on relational database systems. As the Web is becoming more and more data-oriented, there is a need to shift from SQL-based CRUD operations to Semantic Web-based CRUD operations. Learn how to use PHP to perform CRUD operations over the Semantic Web.

Naming: Marvin is named after Marvin, the paranoid android from the Hitchhiker’s Guide to the Galaxy. Marvin has “a brain the size of a planet”, which he is seldomly able to use. Indeed, the true horror of Marvin's existence is that no task he could be given would occupy even the tiniest fraction of his vast intellect.
