The NDSA Levels of Preservation (https://ndsa.org/publications/levels-of-digital-preservation/) should be some help and the Digital Preservation Storage Criteria (https://osf.io/sjc6u/are) designed to help with work like yours.
I am participating in a group (non-NDSA) that is creating a list of requirements or features that archivists would like to see in a digital preservation service. We are in the early stages and thought there has likely been work done in this area, and it would help us to have ideas as a jumping-off point.
Has the Standards group done any work in this area, or does anyone know of another resource?
Any information you can give me would be greatly appreciated.
