We talked about the semantic web and how to integrate semantic technology into Drupal as a module. Our special guest was Stéphane Corlosquet from Deri Galway. Straight away he came from the airport to join our meeting at half past 9 pm. After having a short dinner (a fast hamburger) he presented us his thougts about how Drupal data could be described in RDF. In the attached diagram you can see the current Drupal data structure and the proposed RDF schema

But how could this be realized? Which framework would fit the intended requirements? A possible solution could be ARC. ARCFlexible open source RDF system for semantic web working with PHP and MySQL. is a flexible RDF system for semantic web and PHP developers an easy RDF and SPARQL for LAMP systems. Stephane told us that he is just at the beginning of testing ARC for its usefulness for achieving the desired goals. I’m curious what the output of the planned architecture using ARC will be. Could Drupal, in combination with the RDF module, be the CMS killer application? I’m sure these guys are on the right way. Thank you all guys for this very pleasant evening yesterday. Hope to see you again soon.
