Diego, I absolutely agree. Josh is a good guy, excellent work done (not only) in the linking open data realm. I would even go a step further and query him for more input. I bet he has even more to offer ;) Cheers, Michael ---------------------------------------------------------- Michael Hausenblas, MSc.
