A message received on Oct 27 by some corresponding authors for the CRIS2022 papers to be published in the special issue of Procedia Computer Science for the CRIS2022 conference proceedings states they have already entered production. These messages include a request to fill in the Rights & Access form the publisher requires for the process to move on. In these forms there is an option to select a CC BY 4.0 licence that authors are encouraged to choose.
It may take some corresponding authors an extra day or two to receive these notifications from the publisher. This is because some CRIS2022 papers required some minor updates (missing PDF version or format changes) and may as a consequence take a bit longer to enter the production queue than those which entered it unchanged from the original submission. The info on the progress towards publication is kept updated on a specific page in the euroCRIS website.
