So Nigel, just one question as the next speaker is setting up Thomas. You can start. Why didn't this happen sooner? It seems, I mean I know you've been explaining that it's not as simple, but I mean the rationale seems simple. Why didn't anybody think of this? I mean the rationale folks like that. Ask yourselves why hasn't openness happened forever and why is it still a cause you need to promote and gather support for? There are lots of reasons. I didn't really have a chance to talk about them, but there is a culture of actually governments thinking they know their data best. They don't actually entirely trust people to make sense of it. They employ armours of experts to analyse it before it can go out there. That's just one reason. There was also I think a notion that the idea, they often thought they were doing it. They literally thought that producing it as a PDF report or having built a website that described it buried away in some pages somewhere was publishing the data. One thing that we absolutely require in the future going forward is that sites like NHS Choices that actually have a large amount of data about a sector make the data that drives their websites available using open standards. Because actually one of the problems in many of these areas are the content management systems that are proprietary, that are IT legacy systems in government. Thanks very much.
