 This is a practical guide that provides government and other data custodians a clear framework on which data sets should be made legally open, which data models or standards exist, or how to integrate different data sets. Very often we see different stakeholders group involved in parallel discussions about data needs. So with this guide, we hope that they will find clear framework to decide how to overcome certain challenges. For instance, for example, how to release data without compromising private information. So we believe that this guide will help make land administration more transparent, but also more efficient and modern and ultimately addressing equality and access to land.
