Visualizing iFDO information with icons#

Some of the iFDO fields require using well-defined values for those fields as described in the tables on the specific iFDO sections. For these well-defined values, icons were created to enable visualizing this capture information in web interfaces or data processing reports. These icons are available in the resources folder and an overview is given here. You are free to use these icons. They are released publicly under CC-0.
