RDF is worth learning for a different reason — the profound enlightenment experience you will have when you finally get it. That experience will make you a better format and data API designer for the rest of your days, even if you never actually use RDF itself a lot. (You can get some beginning experience with RDF fairly easily by writing and modifying simple files like FOAF and DOAP for social networks and software projects, or RDFa extensions for XHTML.)

Sμblog (pronounced sub-log) is is my attempt to combine ideas about microblogging, messaging and the sematic web into a practical tool ready for everyday work.

XMPP to RDF microblogging tool, quite nice and well documented.

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.

This document defines a representation of the Hyper Text Transfer Protocol (HTTP) using the Resource Description Framework (RDF). It defines a collection of RDF classes and properties that represent the HTTP vocabulary as defined by the HTTP specification.

In the course of my diploma thesis, I evaluated the performance of several RDF stores when small pieces of information are requested from a large dataset (DBpedia infoboxes plus two very small sets). The benchmark queries employ varying levels of joins and constraints.

we all love benchmarks

WebCamp on Social Network Portability / Kingsley Hotel, Cork / 2nd March 2008

the funkiest slide I've seen for a while.

This implementation report summarizes results from 14 implementations of the SPARQL Query Language for RDF against the RDF Data Access Working Group's query language test suite.

RAP and RDFLib aren't the better ones

Another SemWeb post I meant to link to a while back - Keith Alexander has tips on creating RDF vocabularies or ontologies.

nice starting point

A vocubulary, and a set of processes for representing Atom in RDF

an old thing finally useful? Or should I use SIOC instead?

The three sides of the tri-color cube in these logos evoke the triplet of the RDF model. The peeled back lid invites you to Open Your Data to the Semantic Web!

RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information.

another cool toolbox

Consider this a kind of Hello World of RDF querying.

Nice intro from big Tom using Twitter data.
