Today the UK Government has launched a new, more open licence under which people can use government information and data. The new Open Government Licence allows anyone - businesses, individuals, charities and community groups - to re-use public sector information without having to pay or get permission. It is a simple way for everyone to benefit from the increasing amount of government information published as part of the Prime Minister's Transparency agenda.When Tim Berners-Lee and I first became involved in the effort to open up government data, we identitfied permissive and open licenses as a key requirement.
