As a semantic web researcher and developer, my goal is to bring these technologies to the lay people. The main problem is the common chicken and egg dilemma, where the semantic web technologies need semantic data to become truly useful and powerful, but nobody wants to produce such data until they can see how powerful the semantic web is.

There is an immense amount of data available on the internet spread over millions of HTML pages, PDF documents, et cetera. These formats have been designed for making these documents understandable for people, but not for machines. In this instance RDF comes in as a language to describe data and relationships within the data. From a web of documents we evolve to a web of pieces of data, i.e. concepts, items, ideas, events, people, you name it. Each of them can be identified by their own Uniform Resource Identifier (URI), and the web becomes a global database.

Finally! After much work during the last months, 4 betas and 4 release candidates, it's now official! Drupal 6 is out! It ships with a revamped easy to use installer, a new drag and drop interface, OpenID out of the box, improved Internationalization, and an Update Status module which will help you to keep your site and modules up to date. Also for the developers, new APIs have been integrated in core such as Schema API and Batch API. You can find more details about all the other new features of Drupal 6 in the announcement.

This release is a big reward for the hundreds of developers who put much time and patience into building such a great product. Congrats to Gábor for leading all of us!

Living in a totally drupalized world for 4 days is something I had never experienced before: drupalCon Barcelona 2007 was my first DrupalCon, and it was a really amazing and enriching experience.

Venue: citilab, an old factory newly refurbished, which looks really modern and well designed. I really like the wood color inside the building, which gives it a natural warm and enjoyable atmosphere. We were actually used as guinea pigs: Drupalcon was the first conference in this venue, and it was a success!

Day 1

The event introduction by Bert was really fun and entertaining. Picktek room - the main room - was packed with the 400+ attendees, many people had to remain standing.

I gave my talk at DrupalCon Barcelona on Friday to an audience of about 50 people. I presented some concepts of the Semantic Web and how they are applied in the case of online communities with the SIOC technology. The slides are available for download. I got interesting feedbacks during the presentation, such as Fen Labalme from Civicactions who strongly recommended to avoid using FOAF and to use more secure and privacy friendly technologies such as XRI.

I also gave a quick demo of a prototype drupal site querying a SPARQL endpoint such as dbpedia.org. More people came at the end of the session to greet me, they obviously liked the presentation and the opportunities that the Semantic Web can offer. People were so enthusiastic that we had to continue our conversations outside, and I missed the first half of the next talk! But it was great to see so a great response from the community! Also, thanks to Peter aka Greenman for organizing this session at the first place.

The next day, Jonathan Hendler was talking about the Semantic Search module he created for Drupal.

After some technical difficulties to set up the computer and the video, he went through a short explanation of what RDF means. Someone asked when the Semantic Web would hit us, Jonathan replied that "the Semantic Web already hit us, we just missed it". The audience was quite RDF savvy already, so he quickly moved on to more technical details. The LINC - Leveraging Investments in Creativity site is an online demo of the Semantic Search tool running on a drupal site. He also showed the administration pages which allow you to specify which RDF store you want to use. His module can run on Sesame and on YARS. Jonathan was glad when I announced that YARS2 came out recently and that it was now supporting SPARQL!

Again, some people expressed their interest after the talk, and we decided to move to the BoF room, in order to brainstorm about Drupal and the Semantic Web.

Gábor committed it yesterday night - anytime is good for core hacking! It is a code cleanup that I spotted a few weeks ago. It's not the same as the actual functionality change I am working on at the moment. I talked with webchick about it for about an hour. She liked the idea, and gave me some tips to make it even better. More to come!

The day was good. Great organization, and a big banner at the entrance.
