I would say that the culture change comes from people seeing benefits themselves in how they're using data. The NHS Information Centre is now much more gung-ho on the open data agenda because someone else has come in and provided them with a service and some analysis that was useful to them in doing their day-to-day job. That's the thing that really switches the culture change.
In terms of the behavioural response that you just highlighted, of some people not wanting to collect data because they're worried that they then have to publish it, I haven't seen that. That's partly because, as in the earlier questions we were talking about, the public sector is slightly behind in the collection of data so it tends to only collect data it needs for operational reasons. So you can't stop the collection of the data without also stopping the operations.
