The past two years have witnessed the emergence of a new strain of data - Open Government Data (OGD). Nation states, regional authorities and cities are all setting up OGD programmes. The reasons are numerous and compelling; transparency and accountability, the drive to improve public services, the creation of social and economic value are all seen as reasons to publish public sector information. The UK is a pioneer in this work having put thousands of datasets online. These range from maps tospending data, crime to education data. New engineering and technological approaches have emerged to open data - this linked data capability is a next stage in the development of the Web.
