Hi Mario, Sorry to be slow to get back you. I’ve checked the changes in -25 against my comments and it all looks good to me.
I’ve cleared my discuss. Regards, Rob From: iesg <iesg-boun...@ietf.org> On Behalf Of Mario Loffredo Sent: 28 August 2023 08:57 To: Rob Wilton (rwilton) <rwil...@cisco.com>; The IESG <i...@ietf.org> Cc: draft-ietf-regext-rdap-reverse-sea...@ietf.org; regext-cha...@ietf.org; regext@ietf.org; t...@apnic.net Subject: Re: [regext] Robert Wilton's Discuss on draft-ietf-regext-rdap-reverse-search-24: (with DISCUSS and COMMENT) Hi Robert, need to partially correct my comment about the content of table in Section 12.2.4.2. The "Reference" field is already defined for the "Reverse Search Mapping" registry and for all the entries of that registry the value is the same as that for the entries of the "Reverse Search" registry as it is explained in the second paragraph of Section 12.2.4.2. The "Reference" field in the "Reverse Search Mapping" registry is required to store the link to the documentation supporting the given mapping. The "PropetyPath" field allows the requestor to describe the mapping formally and unambiguously. Therefore, thinking back, there's no need to introduce a "Description" property for that registry. Anyway, if you think the "Description" field should also be included to provide a brief description of the mapping, I'll add it to both 12.2.4.1 and 12.2.4.2 Sections. Looking forward to you reply about this and other points. Best, Mario Il 24/08/2023 15:48, Mario Loffredo ha scritto: Hi Robert, thanks a lot for your review. Please find my comments inline.

Creation of the RDAP Reverse Search Registries These registries follow the Specification Required process as defined in Section 4.5 of [RFC8126]. The designated expert should prevent collisions and confirm that suitable documentation, as described in Section 4.6 of [RFC8126], is available to ensure interoperability. References are not limited only to RFCs and simple definitions could be described in the registries themselves. I'm not sure that "simple definitions could be described in the registries themselves" is consistent with the "Specification Required" policy chosen above. [ML] You are right. I'll change that sentence as in the following: References are not limited only to RFCs but can also locate document published outside of the RFC path, including informal documentation. Does it work for you ? ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- [I support John's discuss on normative references.] I also have some other comments that you may wish to consider: (2) p 14, sec 12.2.4.2. Initial Content +==========+==================================================+ | Property | Property Path | +==========+==================================================+ | fn | $.entities[*].vcardArray[1][?(@[0]=='fn')][3] | +----------+--------------------------------------------------+ | handle | $.entities[*].handle | +----------+--------------------------------------------------+ | email | $.entities[*].vcardArray[1][?(@[0]=='email')][3] | +----------+--------------------------------------------------+ | role | $.entities[*].roles | +----------+--------------------------------------------------+ Would it be helpful for this table to include the "Description" and "Reference" properties? [ML] Do you mean the "Description" and "Reference" related to the specific mapping for the reverse search property or those related to the reverse search property ? In the latter case they are already included in Table 2 and Table 1 respectively. In the first case, they are missing and must be first added to the "RDAP Reverse Search Mapping Registry". Since there might be specifications proposing a diffierent maping for an existing reverse search property it sounds reasonable to me to add both of them. Minor level comments: (3) p 3, sec 1. Introduction The protocol described in this specification aims to extend the RDAP query capabilities and response to enable reverse search based on the relationships defined in RDAP between an object class for search and a related object class. The reverse search based on the domain- entity relationship is treated as a particular case of such a generic model. This introduction text seems to immediately jump into a defense as to why it is okay to standardize this functionality in an RDAP extension. This is okay, but I wonder whether it wouldn't be better if the introduction only included the last paragraph (i.e., that is stating what extension is defined in this document), and the rest of the text was moved into a "Background" subsection of the introduction. [ML] Sounds reasonable to me. Then, the new Introduction section should be arranged as into the following: 1. Introduction The protocol described in this specification aims to extend the RDAP query capabilities and response to enable reverse search based on the relationships defined in RDAP between an object class for search and a related object class. The reverse search based on the domain- entity relationship is treated as a particular case of such a generic model. 1.1 Background Reverse Whois is a service provided by many web applications that allows users to find domain names owned by an individual or a company starting from the owner's details, such as name and email. Even if it has been considered useful for some legal purposes (e.g. uncovering trademark infringements, detecting cybercrimes), its availability as a standardized Whois capability has been objected to for two main reasons, which now don't seem to conflict with an RDAP implementation. ..... ..... ..... Currently, RDAP does not provide any means for a client to search for the collection of domains associated with an entity [RFC9082]. A query (lookup or search) on domains can return the array of entities related to a domain with different roles (registrant, registrar, administrative, technical, reseller, etc.), but the reverse operation is not allowed. Only reverse searches to find the collection of domains related to a nameserver (ldhName or ip) can be requested. Since an entity can be in relationship with any RDAP object [RFC9083], the availability of a reverse search as largely intended can be common to all the object classes allowed for search. Through a further step of generalization, the meaning of reverse search in the RDAP context can be extended to include any query for retrieving all the objects in relationship with another matching a given search pattern. Can you please confirm that it would work for you ? (4) p 7, sec 8. Reverse Searches Based on Entity Details Reverse search property: fn RDAP member path: $.entities[*].vcardArray[1][?(@[0]=='fn')][3] Reference: Section 6.2.1 of [RFC6350] A minor issue, but it wasn't immediately obvious to me what 'fn' is - I initially presumed that it meant function, so I was wondering if some more text would be helpful here, and/or perhaps in the IANA registry that you are creating. [ML] FN is a property of the vCard format [RFC6350] representing the contact name. The JSON format for the vCard data, namely jCard [RFC7095], is used in RDAP responses [RFC9083] to represent contact information (see the member "vcardArray" in the JSONPath expression) jCard specification states that the property names should be in lowercase. The name 'fn' is also used in RDAP as query parameter for seacrhing contacts by name [RFC9082]. Besides being well-known to RDAP operators, think that the value of the "Description" field in the "RDAP Reverse Search" registry makes it clear enough the meaning of the "fn" reverse search property.
