Access to and reuse of public data: open data and open government

Open government is a form of permanent open communication between the administration and citizens, based on transparency from the administration, working with civil society and business. We present one of the key points that are being used to achieve this objective of participation: the open data movement. In Europe, its origins lie in the issuance of Directive 2003/98/EC of the European Parliament and the Council on access to and reuse of public sector information. Open data projects described here provide access to government data according to the recommendations of the W3C. The structure and open format allows data to be reused to provide new services to citizens and businesses. Numerous projects and visualization applications have been developed that realize the potential of this movement. The situation in Spain is emerging and even in a short period of time many initiatives are maturing. This offers us the opportunity to ask what role information managers will take on in this new scenario.
