Does anyone know if there is a best practice for designating data as CUI in a tdms file? I am currently including CUI in the file name and have added a property to the file called classification that lists controlled unclassified information as the value. Just curious if anyone else is doing more than that or if that sounds about right. For more typical file formats that we export (pdfs, power points, etc), we have standards of having CUI at both the top and bottom of each page and we also add a distribution statement on the first page but wasn't sure on these files as you don't view them like you would those other documents so curious if anyone else is doing anything different.
