This book is prepared by EPMA, with inputs of experts, dealing with research and practice of data management for better governance. Originally, this publication was intended to be a supplementary output of the ONE project (Observatory Network to Enhance ICT Structural Funds Absorption), www.oneproject.eu, co- funded by the INTERREG IVC programme of the EU. However, the value of inputs and experiences provided by the contributing authors may boost this book to become a wake-up call towards information economy not only within the ONE project European regions. The publication provides enough evidence supporting the immense relevance of topics incited and challenges tackled by the project partners during the project lifetime, especially those reflected in discussions with wider audience at the ONE Conference Prague 2013.
