Re: Contacts after a Domain Transfer

All,

> I guess that nearly no registry has implemented the transfers of contacts. The benefit is neglectible and introduces some unwanted side effects. As Seth says, especially, automatically transferring contacts along with the domain is a really bad idea, as these contacts may still be linked with other domains of the losing registrar.

We've done the implementation for contact transfer but haven't found a use for it (yet)

> Automatic copying of contacts could be done, but this increases the garbage -- without copying, a registrar can theoretically reuse an existing contact for the very same person he has created earlier.

Contacts are duplicated on transfer and many rars replace these with their own for contact ID uniformity (I would guess), so we're facing a contact garbage collection sometime soon which should be fun...

> Host objects cannot be copied, as the host's name is the (unique) key to the EPP object (contrary to the ID of the contact, which is not part of the content) and therefore no two hosts with the name may exist at the same time.

Funnily enough; host objects are the only object in our registry that are unique to the rar only, i.e two rars can have the same hostname. We copy host objects (with some special control around subordinate and delegated hosts) on transfer as well as contacts. 

It might not be the neatest approach and requires some long term maintenance but it works well enough!
