Many thanks to our scribes, without whom we would have no record of discussion:

Conor Hoekstra,

Guy Davidson,

Peter Sommerlad, and

Frank Birbacher

The minutes from Thursday and Friday afternoon sessions are now on the SG13 Wiki at

http://wiki.edg.com/bin/view/Wg21cologne2019/SG13Thursday

and

http://wiki.edg.com/bin/view/Wg21cologne2019/SG13Friday

I will produce a summary version of the minutes and send it to this email list, most likely though this will have to wait until I am back from the meeting.

Regards,

Roger.
