Data by itself is simply a collection of numbers. It only becomes meaningful when we weave it through context. A context of relevance that creates information - provides insight, creates solutions and solves problems. The Web gives us a fabric of connectedness, but if the data isn't substantiated semantically, the information we create isn't very useful. By building effective web assets using platforms like Drupal, we build ways to solve problems across the spectrum from local to global. We not only build the Web the way it was meant to be, but we also build it to support a commons across community, enterprise and government for generations to come.
