An interesting post on the view from inside on licensing data.
If this data was owned collectively (that is to say, was not owned at all) and such basic factual documents were not seen as money making opportunities we would have so many advantages. Instead, we have a situation where hundreds of hours are being wasted simply because of outdated business models sadly adopted by our government. On top of this, such restrictions are stifling innovation. Google Maps may be able to afford to licence the OS data but the average bedroom developer cannot and so there is a less than optimal level of development in this area.
