[gtld-tech] EPDP recommendations and EPP

Good Morning,

I think I am in agreement with most people on this, that option 3 (or C, whatever it is called) is the best short term solution “define a "convention" that allows the <city> and <cc> elements to contain placeholder values, such as: <city>-</city> and <cc>XX</cc> which pose no data protection issues”.

Though I want to stress that I believe this is just the quick/short term solution and that I believe that the correct way to resolve this is to “update” RFC 5733. At minimum to make city and cc optional but we should really look at what is needed for improving data privacy/protection on the whole. I also believe this work is extremely important and would like to see this as one of the items that the REGEXT group picks up and starts working immediately.

There are a few issues that we need to address, which include:

  1.  Technical Contact – Only 3 optional fields of Name, Phone, and Email are defined in EPDP Team Recommendation #7.  Is the collection of the additional RFC 5733 disallowed?
  2.  Registrant Contact – All of the Registrant data fields are defined as optional in EPDP Team Recommendation #7.  This means that both Technical Contacts and Registrant Contacts would need to get around the required <contact:name>, <contact:city>, and <contact:cc> elements in RFC 5733.
  3.  Contacts Don’t Have a Type – Contacts are created without a type in RFC 5733, where type is based on the link from the domain name.  Since a Contact is an object, it could be a Registrant and Technical contact for a single domain or for many domains.  Who would apply the policy for what fields are set or not set (client, server, or both)?  My recommendation is for the client to apply the policy, since the client has the relationship with the registrant.

To meet the policy, my recommendation is to support RFC 5733 with placeholder values for the <contact:name>, <contact:city>, and <contact:cc> elements to indicate non-existence, to have the servers be flexible to the contact fields set by the client, and to have the clients implement the policy related to what fields of a contact are set based on the type of the contact.  This is not a perfect solution, but it would allow implementing the policy without a great amount of dependencies and complexity (e.g., parallel contact mappings, adding typing to contacts, adding link type rules, and raising the issue of inconsistent server policies).

I agree with your proposal of option 3, with the additional placeholder text for the required <contact:name> element, the server accepting a flexible number of contact fields (empty or placeholder) for all contacts, and the client implementing the policy.

    I tend to prefer the last option. It doesn't have any dependencies on pushing documents through the IETF, and it doesn't get us into developing policy-specific specifications.
