As briefly discussed, I'm afraid we will need to create a different endpoint here, maybe /objects/{object_id}/access:register, because in the latest versions of the DRS specification, there is (unfortunately) already a POST method defined for /objects/{object_id}/access that has a different non-REST-compliant meaning (see here).

Actually, supporting the new DRS versions will require a lot of code changes on DRS-Filer, including some breaking changes, but for now let's just focus on this issue and try to avoid conflicts in the future, when we will do the migration to the latest version.

For the same reason as above, maybe it's better to write PostObjectAccessRegister here.

To keep in the style of the other descriptions, maybe better to write:

The access method was successfully added.

Given that in a POST request the resource ID will generally be created by the implementation, it is the implementation's responsibility to ensure that this type of error does not happen. So you can remove it from the specs.

I think you can just reuse the AccessMethodRegister model/component that is already defined in this file. No need to create a new one.

This should be created by the implementation/service, so no need to put it here.
