Révision du validateur RDF du W3C
Reçu hier dans la journée
Regular users of the RDF validator may have noticed that, over the past few months, the service sometimes had some trouble processing and displaying graphs of validated RDF documents. This was due to a protection mechanism preventing the already overloaded server to spin entirely out of control. The RDF validator now happily sits on a newer, puchier and less loaded machine. As a result, the issue of graphs now showing should become extremely rare.
Vous pouvez donc à nouveau utiliser le validateur RDF du W3C sans souci pour valider vos documents RDF, mais aussi pour afficher les graphes correspondant, grâce à GraphViz, comme par exemple pour les données SIOC de ce billet.
(In)accessibilité des CAPTCHAs et alternatives

Tim-Berners Lee, à propos des blogs et des wikis:
The idea was that anybody who used the web would have a space where they could write and so the first browser was an editor, it was a writer as well as a reader. Every person who used the web had the ability to write something. It was very easy to make a new web page and comment on what somebody else had written, which is very much what blogging is about.
For years I had been trying to address the fact that the web for most people wasn’t a creative space; there were other editors, but editing web pages became difficult and complicated for people. What happened with blogs and with wikis, these editable web spaces, was that they became much more simple.
When you write a blog, you don’t write complicated hypertext, you just write text, so I’m very, very happy to see that now it’s gone in the direction of becoming more of a creative medium.
