  166 1.2.  Data Model                                                           
  167                                                                            
  168    The data model for JSON responses is specified in five sections:        
  169                                                                            
  170    1.  simple data types conveyed in JSON strings                          
  171                                                                            
  172    2.  data structures specified as JSON arrays or objects that are used   
  173        repeatedly when building up larger objects                          
  174                                                                            
  175    3.  object classes representing structured data corresponding to a      
  176        lookup of a single object                                           
  177                                                                            
  178    4.  arrays of objects representing structured data corresponding to a   
  179        search for multiple objects                                         
  180                                                                            
  181    5.  the response to an error                                            
  182                                                                            
  183    The object classes represent responses for two major categories of      
  184    data: responses returned by RIRs for registration data related to IP    
  185    addresses, reverse DNS names, and Autonomous System numbers and         
  186    responses returned by DNRs for registration data related to forward     
  187    DNS names.  The following object classes are returned by both RIRs      
  188    and DNRs:                                                               
  189                                                                            
  190    1.  domains                                                             
  191                                                                            
  192    2.  nameservers                                                         
  193                                                                            
  194    3.  entities                                                            
  195                                                                            
  196    The information served by both RIRs and DNRs for these object classes   
  197    overlap extensively and are given in this document as a unified model   
  198    for both classes of service.                                            
  199                                                                            
  200    In addition to the object classes listed above, RIRs also serve the     
  201    following object classes:                                               
  202                                                                            
  203    1.  IP networks                                                         
  204                                                                            
  205    2.  Autonomous System numbers                                           
  206                                                                            
  207    Object classes defined in this document represent a minimal set of      
  208    what a compliant client/server needs to understand to function          
  209    correctly; however, some deployments may want to include additional     
  210    object classes to suit individual needs.  Anticipating this need for    
  211    extension, Section 2.1 of this document defines a mechanism for         
  212    extending the JSON objects that are described in this document.         
  213                                                                            
  214                                                                            
  215                                                                            
  216

  219                                                                            
  220                                                                            
  221    Positive responses take two forms.  A response to a lookup of a         
  222    single object in the registration system yields a JSON object, which    
  223    is the subject of the lookup.  A response to a search for multiple      
  224    objects yields a JSON object that contains an array of JSON objects     
  225    that are the subject of the search.  In each type of response, other    
  226    data structures are present within the topmost JSON object.             
  227                                                                            
  228 2.  Use of JSON                                                            
  229                                                                            
  230 2.1.  Naming                                                               
  231                                                                            
  232    Clients of these JSON responses SHOULD ignore unrecognized JSON         
  233    members in responses.  Servers can insert members into the JSON         
  234    responses, which are not specified in this document, but that does      
  235    not constitute an error in the response.  Servers that insert such      
  236    unspecified members into JSON responses SHOULD have member names        
  237    prefixed with a short identifier followed by an underscore followed     
  238    by a meaningful name.  It has been observed that these short            
  239    identifiers aid software implementers with identifying the              
  240    specification of the JSON member, and failure to use one could cause    
  241    an implementer to assume the server is erroneously using a name from    
  242    this specification.  This allowance does not apply to jCard [RFC7095]   
  243    objects.  The full JSON name (the prefix plus the underscore plus the   
  244    meaningful name) SHOULD adhere to the character and name limitations    
  245    of the prefix registry described in [RFC7480].  Failure to use these    
  246    limitations could result in slower adoption as these limitations have   
  247    been observed to aid some client programming models.                    
  248                                                                            
  249    Consider the following JSON response with JSON members, all of which    
  250    are specified in this document.

  331 3.  Common Data Types                                                      
  332                                                                            
  333    JSON [RFC7159] defines the data types of a number, character string,    
  334    boolean, array, object, and null.  This section describes the           
  335    semantics and/or syntax reference for common, JSON character strings    
  336    used in this document.                                                  
  337                                                                            
  338    handle:           DNRs and RIRs have registry-unique identifiers that   
  339                      may be used to specifically reference an object       
  340                      instance.  The semantics of this data type as found   
  341                      in this document are to be a registry-unique          
  342                      reference to the closest enclosing object where the   
  343                      value is found.  The data type names "registryId",    
  344                      "roid", "nic-handle", "registrationNo", etc., are     
  345                      terms often synonymous with this data type.  In       
  346                      this document, the term "handle" is used.  The term   
  347                      exposed to users by clients is a presentation issue   
  348                      beyond the scope of this document.                    
  349                                                                            
  350    IPv4 addresses:   The representation of IPv4 addresses in this          
  351                      document uses the dotted-decimal notation.  An        
  352                      example of this textual representation is             
  353                      "192.0.2.0".                                          
  354                                                                            
  355    IPv6 addresses:   The representation of IPv6 addresses in this          
  356                      document follow the forms outlined in [RFC5952].      
  357                      An example of this textual representation is          
  358                      "2001:db8::1:0:0:1".                                  
  359                                                                            
  360    country codes:    Where the identity of a geopolitical nation or        
  361                      country is needed, these identities are represented   
  362                      with the alpha-2 or two-character country code        
  363                      designation as defined in [ISO.3166.1988].  The       
  364                      alpha-2 representation is used because it is freely   
  365                      available, whereas the alpha-3 and numeric-3          
  366                      standards are not.                                    
  367                                                                            
  368    LDH names:        Textual representations of DNS names where the        
  369                      labels of the domain are all "letters, digits,        
  370                      hyphen" labels as described by [RFC5890].  Trailing   
  371                      periods are optional.                                 
  372                                                                            
  373    Unicode names:    Textual representations of DNS names where one or     
  374                      more of the labels are U-labels as described by       
  375                      [RFC5890].  Trailing periods are optional.

  399    The data structure named "rdapConformance" is an array of strings,      
  400    each providing a hint as to the specifications used in the              
  401    construction of the response.  This data structure appears only in      
  402    the topmost JSON object of a response.

  414    specification.  When custom JSON values are inserted into responses,    
  415    conformance to those custom specifications MUST use a string prefixed   
  416    with the appropriate identifier from the IANA RDAP Extensions           
  417    registry specified in [RFC7480].  For example, if the fictional         
  418    Registry of the Moon wants to signify that their JSON responses are     
  419    conformant with their registered extensions, the string used might be   
  420    "lunarNIC_level_0".  These prefixes aid the identification of           
  421    specifications for software implementers, and failure to use them       
  422    could result in slower adoption of extensions.

  443    The "links" array is found in data structures to signify links to       
  444    other resources on the Internet.  The relationship of these links is

  464    "href" JSON value MUST be specified.  All other JSON values are         
  465    OPTIONAL.

  661    Events can be future dated.  One use case for future dating of events   
  662    is to denote when an object expires from a registry.                    
  663                                                                            
  664    The "links" array in this data structure is provided for references     
  665    to the event actor.  In order to reference an RDAP entity, a "rel" of   
  666    "related" and a "type" of "application/rdap+json" is used in the link   
  667    reference.

  674    This data structure, named "status", is an array of strings             
  675    indicating the state of a registered object (see Section 10.2.2 for a   
  676    list of values).

  680    This data structure, a member named "port43", is a simple string        
  681    containing the fully qualified host name or IP address of the WHOIS     
  682    [RFC3912] server where the containing object instance may be found.     
  683    Note that this is not a URI, as there is no WHOIS URI scheme.

handle:           DNRs and RIRs have registry-unique identifiers that
                     may be used to specifically reference an object
                     instance.  The semantics of this data type as found
                     in this document are to be a registry-unique
                     reference to the closest enclosing object where the
                     value is found.  The data type names "registryId",
                     "roid", "nic-handle", "registrationNo", etc., are
                     terms often synonymous with this data type.  In
                     this document, the term "handle" is used.  The term
                     exposed to users by clients is a presentation issue

It should say:
handle:           DNRs and RIRs have registry-unique identifiers that
                     may be used to specifically reference an object
                     instance.  The semantics of this data type as found
                     in this document are to be a registry-unique

                     "roid", "nic-handle", "registrationNo", etc., are

                     simple string.

All uses of handle in section 5 call "handle" out as being a string, but
if a reader were to only read section 3 they would not know it.

  785    Object classes represent structures appropriate for a response from     
  786    the queries specified in [RFC7482].                                     
  787                                                                            
  788    Each object class contains a "links" array as specified in              
  789    Section 4.2.  For every object class instance in a response, whether    
  790    the object class instance is directly representing the response to a    
  791    query or is embedded in other object class instances or is an item in   
  792    a search result set, servers SHOULD provide a link representing a URI   
  793    for that object class instance using the "self" relationship as         
  794    described in the IANA registry specified by [RFC5988].  As explained    
  795    in Section 5.2, this may be not always be possible for nameserver       
  796    data.  Clients MUST be able to process object instances without a       
  797    self link.  When present, clients can use the self link for caching     
  798    data.  Servers MAY provide more than one self link for any given        
  799    object instance.  Failure to provide any self link by a server may      
  800    result in clients being unable to cache object class instances.         
  801                                                                            
  802    Clients using self links for caching SHOULD not cache any object        
  803    class instances where the authority of the self link is different       
  804    than the authority of the server returning the data.  Failing to do     
  805    so might result in cache poisoning.                                     
  806                                                                            
  807    Self links MUST contain a "type" element containing the "application/   
  808    rdap+json" media type when referencing RDAP object instances as         
  809    defined by this document.

  843    The entity object class appears throughout this document and is an      
  844    appropriate response for the /entity/XXXX query defined in              
  845    "Registration Data Access Protocol (RDAP) Query Format" [RFC7482].      
  846    This object class represents the information of organizations,          
  847    corporations, governments, non-profits, clubs, individual persons,      
  848    and informal groups of people.  All of these representations are so     
  849    similar that it is best to represent them in JSON [RFC7159] with one    
  850    construct, the entity object class, to aid in the reuse of code by      
  851    implementers.                                                           
  852                                                                            
  853    The entity object class uses jCard [RFC7095] to represent contact       
  854    information, such as postal addresses, email addresses, phone numbers   
  855    and names of organizations and individuals.  Many of the types of       
  856    information that can be represented with jCard have no use in RDAP,     
  857    such as birthdays, anniversaries, and gender.                           
  858                                                                            
  859    The entity object is served by both RIRs and DNRs.  The following is    
  860    an example of an entity that might be served by an RIR.

It should say:
identifier -- a string denoting a public identifier of the type 
              related to "type"

While the example given in section 4.8 shows "identifier" being a
string, the prose description does not clearly state it.

 1266    Figure 18 is an example of a nameserver object with all values given.   
 1267    Registries using a first-class nameserver data model would embed this   
 1268    in domain objects as well as allowing references to it with the         
 1269    "/nameserver" query type (all depending on the registry operators       
 1270    policy).  Other registries may pare back the information as needed.     
 1271    Figure 19 is an example of a nameserver object as would be found in     
 1272    RIRs and some DNRs, while Figure 20 is an example of a nameserver

 1284    The following is an example of a simple nameserver object that might

 1295    As nameservers can be modeled by some registries to be first-class      
 1296    objects, they may also have an array of entities (Section 5.1)          
 1297    embedded to signify parties responsible for the maintenance,            
 1298    registrations, etc., of the nameservers.

In Section 5.2:
"ldhName" : "ns1.xn--fo-5ja.example",
"unicodeName" : "ns1.foo.example",
It should say:
"ldhName" : "ns1.xn--fo-5ja.example",
"unicodeName" : "ns1.foóo.example",

The unicodeName examples in RFC 7483 are invalid per RFC 5890. Here's an example from Section 5.2 on page 23:

"unicodeName" : "ns1.foo.example",

Section 3 of 7483 says this about Unicode names:

"Unicode names: Textual representations of DNS names where one or more of the labels are U-labels as described by [RFC5890]."

5890 says: "A "U-label" is an IDNA-valid string of Unicode characters, in Normalization Form C (NFC) and including at least one non-ASCII character, expressed in a standard Unicode Encoding Form (such as UTF-8)."

The examples in 7483 contain all ASCII characters. Syntactically valid examples are shown in the corrected text.
 1376 5.3.  The Domain Object Class                                              
 1377                                                                            
 1378    The domain object class represents a DNS name and point of              
 1379    delegation.  For RIRs, these delegation points are in the reverse DNS   
 1380    tree, whereas for DNRs, these delegation points are in the forward      
 1381    DNS tree.                                                               
 1382                                                                            
 1383    In both cases, the high-level structure of the domain object class      
 1384    consists of information about the domain registration, nameserver       
 1385    information related to the domain name, and entities related to the     
 1386    domain name (e.g., registrant information, contacts, etc.).             
 1387

 2038    The IP network object class models IP network registrations found in    
 2039    RIRs and is the expected response for the "/ip" query as defined by     
 2040    [RFC7482].  There is no equivalent object class for DNRs.  The high-    
 2041    level structure of the IP network object class consists of              
 2042    information about the network registration and entities related to      
 2043    the IP network (e.g., registrant information, contacts, etc.).

In Section 5.3:
"ldhName" : "xn--fo-5ja.example",
"unicodeName" : "foo.example",

"ldhName" : "xn--fo-cka.example",
"unicodeName" : "foo.example"

"ldhName" : "xn--fo-fka.example",
"unicodeName" : "foo.example"

"ldhName": "xn--fo-8ja.example",
"unicodeName" : "foo.example"
It should say:
"ldhName" : "xn--fo-5ja.example",
"unicodeName" : "foóo.example",

"ldhName" : "xn--fo-cka.example",
"unicodeName" : "foõo.example"

"ldhName" : "xn--fo-fka.example",
"unicodeName" : "foöo.example"

"ldhName" : "xn--fo-8ja.example",
"unicodeName" : "foôo.example"

The unicodeName examples in RFC 7483 are invalid per RFC 5890. Here's an example from Section 5.2 on page 23:

"unicodeName" : "ns1.foo.example",

Section 3 of 7483 says this about Unicode names:

"Unicode names: Textual representations of DNS names where one or more of the labels are U-labels as described by [RFC5890]."

5890 says: "A "U-label" is an IDNA-valid string of Unicode characters, in Normalization Form C (NFC) and including at least one non-ASCII character, expressed in a standard Unicode Encoding Form (such as UTF-8)."

The examples in 7483 contain all ASCII characters. Syntactically valid examples are shown in the corrected text.
 2262 5.5.  Autonomous System Number Entity Object Class                         
 2263                                                                            
 2264    The Autonomous System number (autnum) object class models Autonomous    
 2265    System number registrations found in RIRs and represents the expected   
 2266    response to an "/autnum" query as defined by [RFC7482].  There is no    
 2267    equivalent object class for DNRs.  The high-level structure of the      
 2268    autnum object class consists of information about the network           
 2269    registration and entities related to the autnum registration (e.g.,     
 2270    registrant information, contacts, etc.) and is similar to the IP        
 2271    network entity object class.                                            
 2272                                                                            
 2273    The following is an example of a JSON object representing an autnum.

 2679    In cases where the data of a response needs to be limited or parts of   
 2680    the data need to be omitted, the response is considered "truncated".    
 2681    A truncated response is still valid JSON, but some of the results in    
 2682    a search set or some of the data in an object are not provided by the   
 2683    server.  A server may indicate this by including a typed notice in      
 2684    the response object.

 2914                                                                            
 2915                                                                            
 2916    Review of registrations into this registry by the designated            
 2917    expert(s) should be narrowly judged on the following criteria:          
 2918                                                                            
 2919    1.  Values in need of being placed into multiple types must be          
 2920        assigned a separate registration for each type.                     
 2921                                                                            
 2922    2.  Values must be strings.  They should be multiple words separated    
 2923        by single space characters.  Every character should be              
 2924        lowercased.  If possible, every word should be given in English     
 2925        and each character should be US-ASCII.                              
 2926                                                                            
 2927    3.  Registrations should not duplicate the meaning of any existing      
 2928        registration.  That is, if a request for a registration is          
 2929        significantly similar in nature to an existing registration, the    
 2930        request should be denied.  For example, the terms "maintainer"      
 2931        and "registrant" are significantly similar in nature as they both   
 2932        denote a holder of a domain name or Internet number resource.  In   
 2933        cases where it may be reasonably argued that machine                
 2934        interpretation of two similar values may alter the operation of     
 2935        client software, designated experts should not judge the values     
 2936        to be of significant similarity.                                    
 2937                                                                            
 2938    4.  Registrations should be relevant to the common usages of RDAP.      
 2939        Designated experts may rely upon the serving of the value by a      
 2940        DNR or RIR to make this determination.                              
 2941                                                                            
 2942    The following sections provide initial registrations into this          
 2943    registry.

section-5.5 Scott Hollenbeck(Technical Erratum #4980) [Reported]
based on outdated version
country -- a string containing the name of the two-character
country code of the autnum
It should say:
country -- a string containing the two-character country
code of the autnum


As described in Section 3, country codes should consistently be
represented as two-character string values. Note that this differs from
the "full name" format used in jCard representations of entity objects.

 3474 11.  Security Considerations                                               
 3475                                                                            
 3476    This specification models information serialized in JSON format.  As    
 3477    JSON is a subset of JavaScript, implementations are advised to follow   
 3478    the security considerations outlined in Section 6 of [RFC7159] to       
 3479    prevent code injection.                                                 
 3480                                                                            
 3481    Though not specific to JSON, RDAP implementers should be aware of the   
 3482    security considerations specified in [RFC7480] and the security         
 3483    requirements and considerations in [RFC7481].                           
 3484                                                                            
 3485    Clients caching data, especially clients using RDAP-specific caches     
 3486    (instead of HTTP-layer caches), should have safeguards to prevent       
 3487    cache poisoning.  See Section 5 for advice on using the self links      
 3488    for caching.                                                            
 3489                                                                            
 3490    Finally, service operators should be aware of the privacy mechanisms    
 3491    noted in Section 13.                                                    
 3492                                                                            
 3493 12.  Internationalization Considerations

 3497    The default text encoding for JSON responses in RDAP is UTF-8           
 3498    [RFC3629], and all servers and clients MUST support UTF-8.              
 3499

 3502    [RFC7480] defines the use of URIs and IRIs in RDAP.                     
 3503

 3506    Section 4.4 defines the use of language tags in the JSON responses      
 3507    defined in this document.

 3523    IDNs are denoted in this specification by the separation of DNS names   
 3524    in LDH form and Unicode form (see Section 3).  Representation of IDNs   
 3525    in registries is described by the "variants" object in Section 5.3      
 3526    and the suggested values listed in Section 10.2.5.                      
 3527                                                                            
 3528 13.  Privacy Considerations

 3530    This specification suggests status values to denote contact and         
 3531    registrant information that has been marked as private and/or has       
 3532    been removed or obscured.  See Section 10.2.2 for the complete list     
 3533    of status values.  A few of the status values indicate that there are   
 3534    privacy concerns associated with the object instance.  The following    
 3535    status codes SHOULD be used to describe data elements of a response     
 3536    when appropriate:                                                       
 3537                                                                            
 3538       private -- The object is not be shared in query responses, unless    
 3539       the user is authorized to view this information.                     
 3540                                                                            
 3541       removed -- Data elements within the object have been collected but   
 3542       have been omitted from the response.  This option can be used to     
 3543       prevent unauthorized access to associated object instances without   
 3544       the need to mark them as private.                                    
 3545                                                                            
 3546       obscured -- Data elements within the object have been collected,     
 3547       but the response value has been altered so that values are not       
 3548       easily discernible.  A value changed from "1212" to "XXXX" is an     
 3549       example of obscured data.  This option may reveal privacy            
 3550       sensitive information and should only be used when data              
 3551       sensitivity does not require a more protective option like           
 3552       "private" or "removed".                                              
 3553

 3690    This document does not provide specific object classes for              
 3691    registrants and contacts.  Instead, the entity object class may be      
 3692    used to represent a registrant or contact.  When the entity object is   
 3693    embedded inside a containing object such as a domain name or IP         
 3694    network, the "roles" string array can be used to signify the            
 3695    relationship.  It is recommended that the values from Section 10.2.4    
 3696    be used.

 3783    In many use cases, it is necessary to hide or obscure the information   
 3784    of a registrant or contact due to policy or other operational           
 3785    matters.  Registries can denote these situations with "status" values   
 3786    (see Section 10.2.2).

 3817    This document does not provide a specific object class for              
 3818    registrars, but like registrants and contacts (see Appendix A.1), the   
 3819    "roles" string array maybe used.  Additionally, many registrars have    
 3820    publicly assigned identifiers.  The publicIds structure (Section 4.8)   
 3821    represents that information.

 3918    Events represent actions that have taken place against a registered     
 3919    object at a certain date and time.  Events have three properties: the   
 3920    action, the actor, and the date and time of the event (which is         
 3921    sometimes in the future).  In some cases, the identity of the actor     
 3922    is not captured.

 4111    The arrays in Figure 40 with the first member of "adr" represent        
 4112    postal addresses.  In the first example, the postal address is given    
 4113    as an array of strings and constitutes a structured address.  For       
 4114    components of the structured address that are not applicable, an        
 4115    empty string is given.  Each member of that array aligns with the

 4117    following data corresponds to the following positional meanings:

 4144    given but that each string is an empty string.                          
 4145

 4148    Section 5.3 defines the "secureDNS" member to represent secure DNS      
 4149    information about domain names.                                         
 4150                                                                            
 4151    DNSSEC provides data integrity for DNS through the digital signing of   
 4152    resource records.  To enable DNSSEC, the zone is signed by one or       
 4153    more private keys and the signatures are stored as RRSIG records.  To   
 4154    complete the chain of trust in the DNS zone hierarchy, a digest of      
 4155    each DNSKEY record (which contains the public key) must be loaded       
 4156    into the parent zone, stored as DS records, and signed by the           
 4157    parent's private key (RRSIG DS record), as indicated in "Resource       
 4158    Records for the DNS Security Extensions" [RFC4034].  Creating the DS    
 4159    records in the parent zone can be done by the registration authority    
 4160    "Domain Name System (DNS) Security Extensions Mapping for the           
 4161    Extensible Provisioning Protocol (EPP)" [RFC5910].                      
 4162                                                                            
 4163    Only DS-related information is provided by RDAP, since other            
 4164    information is not generally stored in the registration database.       
 4165    Other DNSSEC-related information can be retrieved with other DNS        
 4166    tools such as dig.                                                      
 4167                                                                            
 4168    The domain object class (Section 5.3) can represent this information    
 4169    using either the "dsData" or "keyData" object arrays.  Client           
 4170    implementers should be aware that some registries do not collect or     
 4171    do not publish all of the secure DNS meta-information.

 4181 Appendix E.  Motivations for Using JSON                                    
 4182                                                                            
 4183    This section addresses a common question regarding the use of JSON      
 4184    over other data formats, most notably XML.                              
 4185                                                                            
 4186    It is often pointed out that many DNRs and one RIR support the EPP      
 4187    [RFC5730] standard, which is an XML serialized protocol.  The logic     
 4188    is that since EPP is a common protocol in the industry, it follows      
 4189    that XML would be a more natural choice.  While EPP does influence      
 4190    this specification quite a bit, EPP serves a different purpose, which   
 4191    is the provisioning of Internet resources between registries and        
 4192    accredited registrars and serving a much narrower audience than that    
 4193    envisioned for RDAP.                                                    
 4194                                                                            
 4195    By contrast, RDAP has a broader audience and is designed for public     
 4196    consumption of data.  Experience from RIRs with first generation        
 4197    RESTful web services for WHOIS indicate that a large percentage of      
 4198    clients operate within browsers and other platforms where full-blown    
 4199    XML stacks are not readily available and where JSON is a better fit.    
 4200                                                                            
 4201    Additionally, while EPP is used in much of the DNR community it is      
 4202    not a universal constant in that industry.  And finally, EPP's use of   
 4203    XML predates the specification of JSON.  If EPP had been defined        
 4204    today, it may very well have used JSON instead of XML.                  
 4205                                                                            
 4206    Beyond the specific DNR and RIR communities, the trend in the broader   
 4207    Internet industry is also switching to JSON over XML, especially in     
 4208    the area of RESTful web services (see [JSON_ascendancy]).  Studies      
 4209    have also found that JSON is generally less bulky and consequently      
 4210    faster to parse (see [JSON_performance_study]).                         
 4211

section-10.2.3 Scott Hollenbeck(Technical Erratum #6158) [Reported]
based on outdated version
Description: The object instance was transferred from one registrant to another.
It should say:
Description: The object instance was transferred from one registrar to another.

I believe the corrected text is what was intended for this particular
registry value, and is what is being implemented by operators today.
Registrant-to-registrant transfers are also possible, but they're not
performed using EPP and are not logged as an event action. The text in
the RFC should be changed and the description of the action in the IANA
registry should also be changed.
