EBAS template for mandatory metadata elements

Template describing the mandatory metadata elements that must be applied in the metadata header regardless of measurement principle used.

Points to note

Clicking on a specific line in the example template will provide a detailed explanation and possible options for each of the metadata elements. Please contact ebas@nilu in case of broken links etc.

Downloading template as text file

You could download the template and start to modify the text with your own metadata. Due to limitations of the online portal we could not provide files with the .nas file extension. So please download the text file and edit, and remember to use the .nas file-extension when you create your datafile: 


* To validate the file, please use the EBAS Submission Tool


Apply '000' for valid measurements
