I used to associate Heidi with the little girl frolicking around Swiss mountains, but that is also the name that was chosen for the new system of storing and sharing health information in the EU. (HEIDI: A new way of sharing and storing health information in the EU!) HEIDI (Health in Europe: Information and Data Interface) has been launched by the DG for Health and Consumers and is a sort of wiki database on health in the EU. The content of HEIDI is written by European health experts, not by the employees of the European Commission. The information shared in HEIDI concerns health status, health determinants, systems and policies and is going to be updated on a regular basis directly by the health experts. The data can be sorted per year, by country of by region and will be showed by use of a variety of graphs which will allow for easy comparisons.
