Hi Martin,

A group membership would still boil down to the permissions given to that group.

So if you have a user who you need to be a Submitter on Folder A and they're expected to also read the data there as well, Reader access to Folder A would have to exist somewhere for that user - either individually or as apart of a group.

Also, with some roles (e.g. Author and Submitter), the role will need to be supported by the code that's supplying each specific kind of data. This is because it's often somewhat complicated to know exactly what data is "owned" by each user.

It does seem like that the Submitter permissions would be reasonably supported for a module-defined schema, but a fair amount of new feature coding would be involved to make this happen.

Regards,

Jon
