# Appendix F- Special Considerations for Object Types
This is a list of actions required of the Maintainer in a situation where one of the following object types references the person object to be removed and:
- This is the only person or role object referenced in the object.
- There are no options available for changing the reference.
Forward domain
This is a Top-Level Domain (TLD) problem. If the TLD is not responsive, the TLD should remove its data from the RIPE Database.
Reverse domain
These objects should be deleted and removed from the DNS system.
inet(6)num
The address space must be returned to the appropriate Internet Registry and then the object can be deleted.
The RIPE NCC will take no action until the Data Subject has cancelled any routing arrangements for the address space to be returned and any related route(6) objects have been deleted.
aut-num
These objects should be deleted.
The RIPE NCC will take no action until the Data Subject has cancelled any routing arrangements where this AS number is the origin and any related route(6) objects have been deleted.
role
If the role object only references this one person object, find all the references to the role object and
consider them as if they were direct references to the person object.
mntner
Find all objects that reference this mntner object and carry out the following actions on each of these objects:
- Where there are references to more than one mntner object in the same attribute type, remove the reference to this mntner object.
- If it is referenced in an optional attribute, remove the attribute.
- Where an object references only this mntner object in a single instance of a mandatory attribute, consider this object as if it had a single reference to the person object to be deleted. This object may also need to be deleted and then follow the chain of references to this object and handle all referencing objects according to this list.
When all references to the mntner object have been removed, delete the mntner object.
key-cert
References to person objects are optional, so remove any reference to this person object from the key-cert
object.
irt
Remove references to this irt object from inet(6)num objects, then delete the irt object.
organisation
References to person objects are optional, so remove any reference to this person object from the
organisation object.
