Detlef, I prefer the updated version as sent by Steve Capell, particularly on IPR. IPR issues can get very tricky and being prepared to make contributions fit in the target body would be good. Further suggestions: * Firstly, on the scope of work: this is a useful study, but it is not clear what is to be done with the results of this study. If the ultimate aim is to feed the results into standardisation activities and/or provide advice to organisations providing Vaccination Certificates, it would be good to say so. * The second is about membership of the group. It should be stated, who can join, and also importantly what knowledge and experience does the membership brings to the table. * Finally, a small type on section 2 last paragraph “propote” should be “promote”.

I will try and attend but this may not be possible.

Thank you for the info. I’ll keep the fingers crossed.

My main aim is to assist the group in getting in touch with ETSI eHealth group regarding possible liaison and exchange of information.

Great. Could have a look at the very rudimentary draft of a Charter <https://cloud.eid.as/index.php/s/Q5cq4e2aCt9n699> https://cloud.eid.as/index.php/s/Q5cq4e2aCt9n699 ? Is there anything important missing to move forward towards getting in touch with the ETSI eHealth folks? Nick
