oai.rkbexplorer.com
by parmentierf (via)
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.

by parmentierf
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.
Open Anzo
by parmentierf
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.

Building Semantic Web CRUD operations using PHP
by parmentierf & 1 other
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.
ARQ - Property Paths
by greut
A property path expression (or just 'path') is similar to a string regular expression but over properties, not characters. ARQ determines all matches of a path expression and binds subject or object as appropriate. Only one match is recorded - no duplicates for any given path expression, although is the path is used in a situation where it's initial points is already repeated in a pattern, then this duplication is preserved.
RegExp ou XPath appliqué à un graphe? Intéressant, mais peut-être abscons.
