1.  Introduction

   Domain Name Registries may operate in special modes for certain
   periods of time, enabling Trademark Holders to protect their rights
   during the introduction of a Top-Level Domain (TLD).

   Along with the introduction of new generic TLDs (gTLDs), two special
   modes came into effect:

   *  Sunrise Period: The Sunrise Period allows Trademark Holders an
      advance opportunity to register domain names corresponding to
      their marks before names are generally available to the public.

   *  Trademark Claims Period: The Trademark Claims Period follows the
      Sunrise Period and runs for at least the first 90 days of an
      initial operating period of general registration.  During the
      Trademark Claims Period, anyone attempting to register a domain
      name matching a mark that is recorded in the ICANN Trademark
      Clearinghouse (TMCH) will receive a notification displaying the
      relevant mark information.

   This document describes the requirements, the architecture, and the
   interfaces between the ICANN TMCH and Domain Name Registries (called
   "Registries" in the rest of the document), as well as between the
   ICANN TMCH and Domain Name Registrars (called "Registrars" in the
   rest of the document) for the provisioning and management of domain
   names during Sunrise and Trademark Claims Periods.

   For any date and/or time indications, Coordinated Universal Time
   (UTC) applies.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

   XML is case sensitive.  Unless stated otherwise, XML specifications
   and examples provided in this document MUST be interpreted in the
   character case presented in order to develop a conforming
   implementation.

   "tmNotice-1.0" is used as an abbreviation for
   "urn:ietf:params:xml:ns:tmNotice-1.0".  The XML namespace prefix
   "tmNotice" is used, but implementations MUST NOT depend on it and
   instead employ a proper namespace-aware XML parser and serializer to
   interpret and output the XML documents.

   Extensible Markup Language (XML) 1.0, as described in
   [W3C.REC-xml-20081126], and XML Schema notation, as described in
   [W3C.REC-xmlschema-1-20041028] and [W3C.REC-xmlschema-2-20041028],
   are used in this specification.

3.  Glossary

   In the following section, the most common terms are briefly
   explained:

   Backend Registry Operator:  An entity that manages (a part of) the
      technical infrastructure for a Registry Operator.  The Registry
      Operator may also be the Backend Registry Operator.

   CA:  Certification Authority.  See [RFC5280].

   CNIS:  Claims Notice Information Service.  This service provides
      Trademark Claims Notices (TCNs) to Registrars.

   CRC32:  Cyclic Redundancy Check.  This algorithm is used in the ISO
      3309 standard and in Section 8.1.1.6.2 of ITU-T recommendation
      V.42.

   CRL:  Certificate Revocation List.  See [RFC5280].

   CSV:  Comma-Separated Values.  See [RFC4180].

   datetime:  Date and time.  The date and time are specified following
      the standard specification "Date and Time on the Internet:
      Timestamps".  See [RFC3339].

   DN:  Domain Name.  See [RFC8499].

   DNL:  Domain Name Label.  The DNL is an A-label or a Non-Reserved LDH
      (NR-LDH) label.  See [RFC5890].

   DNL List:  A list of DNLs that are covered by a PRM.

   DNROID:  DN Repository Object IDentifier.  This identifier is
      assigned by the Registry to each DN object that unequivocally
      identifies said DN object.  For example, if a new DN object is
      created for a name that existed in the past, the DN objects will
      have different DNROIDs.

   DNS:  Domain Name System.  See [RFC8499].

   Effective Allocation:  A DN is considered effectively allocated when
      the DN object for the DN has been created in the SRS of the
      Registry and has been assigned to the effective user.  A DN object
      in status "pendingCreate" or any other status that precedes the
      first time a DN is assigned to an end user is not considered an
      effective allocation.  A DN object created internally by the
      Registry for subsequent delegation to another Registrant is not
      considered an effective allocation.

   EPP:  Extensible Provisioning Protocol.  See [RFC8499].

   FQDN:  Fully Qualified Domain Name.  See [RFC8499].

   HTTP:  Hypertext Transfer Protocol.  See [RFC9110].

   HTTPS:  HTTP over TLS (Transport Layer Security).  See [RFC9110].

   ICANN TMCH:  A central repository for information to be
      authenticated, stored, and disseminated, pertaining to the rights
      of TMHs.  The ICANN TMCH is split into two functions: TMV and TMDB
      (see below).  There could be several entities performing the TMV
      function but only one entity performing the TMDB function.

   ICANN TMCH-CA:  The Certification Authority (CA) for the ICANN TMCH.
      This CA is operated by ICANN.  The public key for this CA is the
      trust anchor used to validate the identity of each TMV.

   IDN:  Internationalized Domain Name.  See [RFC8499].

   Lookup Key:  A random string of up to 51 characters from the set [a-
      zA-Z0-9/] to be used as the lookup key by Registrars to obtain the
      TCN using the CNIS.  Lookup keys are unique and are related to one
      DNL only.

   LORDN:  List of Registered Domain Names.  This is the list of
      effectively allocated DNs matching a DNL of a PRM.  Registries
      will upload this list to the TMDB (during the NORDN process).

   Matching Rules:  Some trademarks entitled to inclusion in the TMDB
      include characters that are impermissible in the DNS as a DNL.
      The TMV changes (using the ICANN TMCH Matching Rules
      [MatchingRules]) certain DNS-impermissible characters in a
      trademark into DNS-permissible equivalent characters.

   NORDN:  Notification of Registered Domain Names.  This is the process
      by which Registries upload their recent LORDN to the TMDB.

   PGP:  Pretty Good Privacy.  See [RFC4880].

   PKI:  Public Key Infrastructure.  See [RFC5280].

   PRM:  Pre-Registered Mark.  A mark that has been pre-registered with
      the ICANN TMCH.

   QLP Period:  Qualified Launch Program Period.  During this optional
      period, a special process applies to DNs matching the Sunrise List
      (SURL) and/or the DNL List to ensure that TMHs are informed of a
      DN matching their PRM.

   Registrant:  See the definition of Registrant in [RFC8499].

   Registrar:  Domain Name Registrar.  See [RFC8499].

   Registry:  Domain Name Registry, Registry Operator.  See [RFC8499].
      A Registry Operator is the contracting party with ICANN for the
      TLD.

   SMD:  Signed Mark Data.  A cryptographically signed token issued by
      the TMV to the TMH to be used in the Sunrise Period to apply for a
      DN that matches a DNL of a PRM.  See [RFC7848].  An SMD generated
      by an ICANN-approved Trademark Validator (TMV) contains both the
      signed token and the TMV's PKIX certificate.

   SMD File:  A file containing the SMD (see above) and some human-
      readable data.  The latter is usually ignored in the processing of
      the SMD File.  See Section 6.4.

   SMD Revocation List:  The SMD Revocation List is used by Registries
      (and optionally by Registrars) during the Sunrise Period to ensure
      that an SMD is still valid (i.e., not revoked).  The SMD
      Revocation List has a similar function as CRLs used in PKI.

   SRS:  Shared Registration System.  See [ICANN-GTLD-AGB-20120604].

   Sunrise Period:  During this period, DNs matching a DNL of a PRM can
      be exclusively obtained by the respective TMHs.  For DNs matching
      a PRM, a special process applies to ensure that TMHs are informed
      on the effective allocation of a DN matching their PRM.

   SURL:  Sunrise List.  The list of DNLs that are covered by a PRM and
      are eligible for Sunrise.

   TCN:  Trademark Claims Notice, Claims Notice, Trademark Notice.  A
      Trademark Claims Notice consists of one or more Trademark Claims
      and is provided to prospective Registrants of DNs.

   TCNID:  Trademark Claims Notice Identifier.  An element of the
      Trademark Claims Notice (see above), identifying said TCN.  The
      Trademark Claims Notice Identifier is specified in the element
      <tmNotice:id>.

   TLD:  Top-Level Domain Name.  See [RFC8499].

   TMDB:  Trademark Clearinghouse Database.  This serves as a database
      of the ICANN TMCH to provide information to the gTLD Registries
      and Registrars to support Sunrise or Trademark Claims services.
      There is only one TMDB in the ICANN TMCH that concentrates the
      information about the "verified" trademark records from the TMVs.

   TMH:  Trademark Holder.  The person or organization owning rights on
      a mark.

   TMV:  Trademark Validator, Trademark Validation organization.  An
      entity authorized by ICANN to authenticate and validate
      registrations in the TMDB, ensuring the marks qualify as
      registered, are court-validated marks, or are protected by statute
      or treaty.  This entity would also be asked to ensure that proof
      of use of marks is provided, which can be demonstrated by
      furnishing a signed declaration and one specimen of current use.

   Trademark, Mark:  Marks are used to claim exclusive properties of
      products or services.  A mark is typically a name, word, phrase,
      logo, symbol, design, image, or a combination of these elements.
      For the scope of this document, only textual marks are relevant.

   Trademark Claims, Claims:  Provides information to enhance the
      understanding of the trademark rights being claimed by the TMH.

   Trademark Claims Period:  During this period, a special process
      applies to DNs matching the DNL List to ensure that TMHs are
      informed of a DN matching their PRM.  For DNs matching the DNL
      List, Registrars show a TCN to prospective Registrants that has to
      be acknowledged before effective allocation of the DN.

   UTC:  Coordinated Universal Time.  This is maintained by the Bureau
      International des Poids et Mesures (BIPM).  See [RFC3339].

   Figure 2 depicts the architecture of the Trademark Claims Period,
   including all the actors and interfaces.

4.3.  Interfaces

   The subsections below contain short descriptions of each interface to
   provide an overview of the architecture.  More detailed descriptions
   of the relevant interfaces are in Section 5.

4.3.1.  hv

   The TMH registers a mark with a TMV via the hv interface.

   After successful registration of the mark, the TMV makes a Signed
   Mark Data (SMD) File available (see Section 6.4) to the TMH to be
   used during the Sunrise Period.

   The specifics of the hv interface are beyond the scope of this
   document.

4.3.2.  vd

   After successful registration of the mark, the TMV ensures the TMDB
   inserts the corresponding DNLs and marks information into the
   database via the vd interface.

   The specifics of the vd interface are beyond the scope of this
   document.

4.3.3.  dy

   During the Trademark Claims Period, the Registry fetches the latest
   DNL List from the TMDB via the dy interface at regular intervals.
   The protocol used on the dy interface is HTTPS.

   This interface is not relevant during the Sunrise Period.

4.3.4.  tr

   The Registrant communicates with the Registrar via the tr interface.

   The specifics of the tr interface are beyond the scope of this
   document.

4.3.5.  ry

   The Registrar communicates with the Registry via the ry interface.
   The ry interfaces are typically implemented in EPP.

4.3.6.  dr

   During the Trademark Claims Period, the Registrar fetches the TCN
   from the TMDB (to be displayed to the Registrant via the tr
   interface) via the dr interface.  The protocol used for fetching the
   TCN is HTTPS.

   This interface is not relevant during the Sunrise Period.

4.3.7.  yd

   During the Sunrise Period, the Registry notifies the TMDB via the yd
   interface of all DNs effectively allocated.

   During the Trademark Claims Period, the Registry notifies the TMDB
   via the yd interface of all DNs effectively allocated that matched an
   entry in the DNL List that the Registry previously downloaded during
   the creation of the DN.

   The protocol used on the yd interface is HTTPS.

4.3.8.  dv

   The TMDB notifies the TMV via the dv interface of all effectively
   allocated DNs that match a mark registered by that TMV.

   The specifics of the dv interface are beyond the scope of this
   document.

4.3.9.  vh

   The TMV notifies the TMH via the vh interface after an effectively
   allocated DN matches a PRM of this THM.

   The specifics of the vh interface are beyond the scope of this
   document.

4.3.10.  vs

   The TMV requests to add revoked SMDs to the SMD Revocation List at
   the TMDB.

   The specifics of the vs interface are beyond the scope of this
   document.

   This interface is not relevant during the Trademark Claims Period.

4.3.11.  sy

   During the Sunrise Period, the Registry fetches the most recent SMD
   Revocation List from the TMDB via the sy interface in regular
   intervals.  The protocol used on the sy interface is HTTPS.

   This interface is not relevant during the Trademark Claims Period.

4.3.12.  sr

   During the Sunrise Period, the Registrar may fetch the most recent
   SMD Revocation List from the TMDB via the sr interface.  The protocol
   used on the sr interface is the same as on the sy interface (see
   above), i.e., HTTPS.

   This interface is not relevant during the Trademark Claims Period.

4.3.13.  vc

   The TMV registers its public key and requests to revoke an existing
   key with the ICANN TMCH-CA over the vc interface.

   The specifics of the vc interface are beyond the scope of this
   document, but it involves personal communication between the
   operators of the TMV and the operators of the ICANN TMCH-CA.

   This interface is not relevant during the Trademark Claims Period.

4.3.14.  cy

   During the Sunrise Period, the Registry fetches the most recent TMV
   CRL file from the ICANN TMCH-CA via the cy interface at regular
   intervals.  The TMV CRL is used for validation of TMV certificates.
   The protocol used on the cy interface is HTTPS.

   This interface is not relevant during the Trademark Claims Period.

4.3.15.  cr

   During the Sunrise Period, the Registrar optionally fetches the most
   recent TMV CRL file from the ICANN TMCH-CA via the cr interface at
   regular intervals.  The TMV CRL is used for validation of TMV
   certificates.  The protocol used on the cr interface is HTTPS.

   This interface is not relevant during the Trademark Claims Period.

      Figure 3: Domain Name Registration during the Sunrise Period

   Figure 3 represents a synchronous DN registration workflow (usually
   called first come first served).

5.2.2.  Sunrise Domain Name Registration by Registries

   Registries MUST perform a minimum set of checks for verifying each DN
   registration during the Sunrise Period upon reception of a
   registration request over the ry interface (Section 4.3.5).  If any
   of these checks fail, the Registry MUST abort the registration.  Each
   of these checks MUST be performed before the DN is effectively
   allocated.

   In case of asynchronous registrations (e.g., auctions), the minimum
   set of checks MAY be performed when creating the intermediate object
   (e.g., a DN application) used for DN registration.  If the minimum
   set of checks is performed when creating the intermediate object
   (e.g., a DN application), a Registry MAY effectively allocate the DN
   without performing the minimum set of checks again.

   Performing the minimum set of checks, Registries MUST verify that:

   1.  an SMD has been received from the Registrar, along with the DN
       registration,

   2.  the certificate of the TMV has been correctly signed by the ICANN
       TMCH-CA (the certificate of the TMV is contained within the SMD),

   3.  the datetime when the validation is done is within the validity
       period of the TMV certificate,

   4.  the certificate of the TMV is not listed in the TMV CRL file
       specified in the CRL distribution point of the TMV certificate,

   5.  the signature of the SMD (signed with the TMV certificate) is
       valid,

   6.  the datetime when the validation is done is within the validity
       period of the SMD based on <smd:notBefore> and <smd:notAfter>
       elements,

   7.  the SMD has not been revoked, i.e., is not contained in the SMD
       Revocation List, and

   8.  the leftmost DNL of the DN being effectively allocated matches
       one of the label (<mark:label>) elements in the SMD.  For
       example, if the DN "xn--mgbachtv.xn--mgbh0fb" is being
       effectively allocated, the leftmost DNL would be "xn--mgbachtv".

   These procedures apply to all DN effective allocations at the second
   level, as well as to all other levels subordinate to the TLD that the
   Registry accepts registrations for.

5.2.3.  TMDB Sunrise Services for Registries

5.2.3.1.  SMD Revocation List

   A new SMD Revocation List MUST be published by the TMDB twice a day,
   by 00:00:00 and 12:00:00 UTC.

   Registries MUST refresh the latest version of the SMD Revocation List
   at least once every 24 hours.

   Note: The SMD Revocation List will be the same regardless of the TLD.
   If a Backend Registry Operator manages the infrastructure of several
   TLDs, the Backend Registry Operator could refresh the SMD Revocation
   List once every 24 hours, and the SMD Revocation List could be used
   for all the TLDs managed by the Backend Registry Operator.

5.2.3.2.  TMV Certificate Revocation List (CRL)

   Registries MUST refresh their local copy of the TMV CRL file at least
   once every 24 hours using the CRL distribution point specified in the
   TMV certificate.

   Operationally, the TMV CRL file and CRL distribution point are the
   same for all TMVs and (at publication of this document) are located
   at <http://crl.icann.org/tmch.crl>.

   Note: The TMV CRL file will be the same regardless of the TLD.  If a
   Backend Registry Operator manages the infrastructure of several TLDs,
   the Backend Registry Operator could refresh the TMV CRL file once
   every 24 hours, and the TMV CRL file could be used for all the TLDs
   managed by the Backend Registry Operator.

   initiated by the Registry.

5.2.3.3.  Notice of Registered Domain Names (NORDN)

   The Registry MUST send a LORDN file containing DNs effectively
   allocated to the TMDB (over the yd interface; see Section 4.3.7).

   The effective allocation of a DN MUST be reported by the Registry to
   the TMDB within 26 hours of the effective allocation of such DN.

   The Registry MUST create and upload a LORDN file in case there are
   effective allocations in the SRS that have not been successfully
   reported to the TMDB in a previous LORDN file.

   Based on the timers used by TMVs and the TMDB, the RECOMMENDED
   maximum frequency to upload LORDN files from the Registries to the
   TMDB is every 3 hours.

   It is RECOMMENDED that Registries try to upload at least two LORDN
   files per day to the TMDB, with enough time in between, in order to
   have time to fix problems reported in the LORDN file.

   The Registry SHOULD upload a LORDN file only when the previous LORDN
   file has been processed by the TMDB and the related LORDN Log file
   has been downloaded and processed by the Registry.

   The Registry MUST upload LORDN files for DNs that are effectively
   allocated during the Sunrise or Trademark Claims Periods (same
   applies to DNs that are effectively allocated using applications
   created during the Sunrise or Trademark Claims Periods in case of
   using asynchronous registrations).

   The yd interface (Section 4.3.7) MUST support at least one (1) and
   MAY support up to ten (10) concurrent connections from each IP
   address registered by a Registry Operator to access the service.

   The TMDB MUST process each uploaded LORDN file and make the related
   log file available for Registry download within 30 minutes of the
   finalization of the upload.

 Figure 7: Domain Name Registration during the Trademark Claims Period

   Figure 7 represents a synchronous DN registration workflow (usually
   called first come first served).

5.3.2.  Trademark Claims Domain Name Registration by Registries

   During the Trademark Claims Period, Registries perform two main
   functions:

   *  Registries MUST provide Registrars (over the ry interface; see
      Section 4.3.5) the lookup key used to retrieve the TCNs for DNs
      that match the DNL List.

   *  Registries MUST provide the lookup key only when queried about a
      specific DN.

   In the following instances, a minimum set of checks are described:

   *  For each DN matching a DNL of a PRM, Registries MUST perform a
      minimum set of checks for verifying DN registrations during the
      Trademark Claims Period upon reception of a registration request
      over the ry interface (Section 4.3.5).  If any of these checks
      fail, the Registry MUST abort the registration.  Each of these
      checks MUST be performed before the DN is effectively allocated.

   *  In case of asynchronous registrations (e.g., auctions), the
      minimum set of checks MAY be performed when creating the
      intermediate object (e.g., a DN application) used for DN effective
      allocation.  If the minimum set of checks is performed when
      creating the intermediate object (e.g., a DN application), a
      Registry MAY effectively allocate the DN without performing the
      minimum set of checks again.

   *  Performing the minimum set of checks, Registries MUST verify that:

      1.  The TCNID (<tmNotice:id>), expiration datetime
          (<tmNotice:notAfter>), and acceptance datetime of the TCN have
          been received from the Registrar, along with the DN
          registration.

          If the three elements mentioned above are not provided by the
          Registrar for a DN matching a DNL of a PRM, but the DNL was
          inserted (or reinserted) for the first time into the DNL List
          less than 24 hours ago, the registration MAY continue without
          this data, and the tests listed below are not required to be
          performed.

      2.  The TCN has not expired (according to the expiration datetime
          sent by the Registrar).

      3.  The acceptance datetime is within the window of time defined
          by ICANN policy.  In the gTLD round of 2012, Registrars
          verified that the acceptance datetime was less than or equal
          to 48 hours in the past, as there were no defined ICANN
          policies at that time.  Implementers should be aware that
          ICANN policy may define this value in the future.

      4.  The TCN Checksum is computed using the leftmost DNL of the DN
          being effectively allocated, the expiration datetime provided
          by the Registrar, and the TMDB Notice Identifier extracted
          from the TCNID provided by the Registrar.  Verify that the
          computed TCN Checksum matches the TCN Checksum present in the
          TCNID.  For example, if the DN "xn--mgbachtv.xn--mgbh0fb" is
          being effectively allocated, the leftmost DNL would be "xn--
          mgbachtv".

   These procedures apply to all DN registrations at the second level,
   as well as to all other levels subordinate to the TLD that the
   Registry accepts registrations for.

5.3.3.  TMDB Trademark Claims Services for Registries

5.3.3.1.  Domain Name Label (DNL) List

   A new DNL List MUST be published by the TMDB twice a day, by 00:00:00
   and 12:00:00 UTC.

   Registries MUST refresh the latest version of the DNL List at least
   once every 24 hours.


       .----------.                        .------.

                      Figure 8: Update of the DNL List

   Figure 8 depicts the process of downloading the latest DNL List
   initiated by the Registry.

   Note: The DNL List will be the same regardless of the TLD.  If a
   Backend Registry Operator manages the infrastructure of several TLDs,
   the Backend Registry Operator could refresh the DNL List once every
   24 hours, and the DNL List could be used for all the TLDs managed by
   the Backend Registry Operator.

5.3.3.2.  Notice of Registered Domain Names (NORDN)

   The NORDN process during the Trademark Claims Period is almost the
   same as during the Sunrise Period, as defined in Section 5.2.3.3; the
   difference is that only registrations subject to a Trademark Claim
   (i.e., at registration time, the name appeared in the current DNL
   List downloaded by the Registry Operator) are included in the LORDN.

5.3.4.  Trademark Claims Domain Name Registration by Registrars

   For each DN matching a DNL of a PRM, Registrars MUST perform the
   following steps:

   1.  Use the lookup key received from the Registry to obtain the TCN
       from the TMDB using the dr interface (Section 4.3.6).  Registrars
       MUST only query for the lookup key of a DN that is available for
       registration.

   2.  Present the TCN to the Registrant, as described in Exhibit A of
       [RPM-Requirements].

   3.  Ask the Registrant for acknowledgement, i.e., the Registrant MUST
       consent with the TCN, before any further processing.  (The
       transmission of a TCNID to the Registry over the ry interface
       (Section 4.3.5) implies that the Registrant has expressed their
       consent with the TCN.)

   4.  Perform the minimum set of checks for verifying DN registrations.
       If any of these checks fail, the Registrar MUST abort the DN
       registration.  Each of these checks MUST be performed before the
       registration is sent to the Registry.  Performing the minimum set
       of checks, Registrars MUST verify the following:

       a.  The datetime when the validation is done is within the TCN
           validity based on the <tmNotice:notBefore> and
           <tmNotice:notAfter> elements.

       b.  The leftmost DNL of the DN being effectively allocated
           matches the label (<tmNotice:label>) element in the TCN.  For
           example, if the DN "xn--mgbachtv.xn--mgbh0fb" is being
           effectively allocated, the leftmost DNL would be "xn--
           mgbachtv".

       c.  The Registrant has acknowledged (expressed their consent
           with) the TCN.

   5.  Record the date and time when the registrant acknowledged the
       TCN.

   6.  Send the registration to the Registry (via the ry interface; see
       Section 4.3.5) and include the following information:

       *  TCNID (<tmNotice:id>)

       *  Expiration date of the TCN (<tmNotice:notAfter>)

       *  Acceptance datetime of the TCN

   Currently, TCNs are generated twice a day by the TMDB.  The
   expiration date (<tmNotice:notAfter>) of each TCN MUST be set to a
   value defined by ICANN policy.  In the gTLD round of 2012, the TMDB
   set the expiration value to 48 hours into the future, as there were
   no defined ICANN policies at that time.  Implementers should be aware
   that ICANN policy may define this value in the future.

   Registrars SHOULD implement a cache of TCNs to minimize the number of
   queries sent to the TMDB.  A cached TCN MUST be removed from the
   cache after the expiration date of the TCN, as defined by
   <tmNotice:notAfter>.

   The TMDB MAY implement rate limiting as one of the protection
   mechanisms to mitigate the risk of performance degradation.

5.3.5.  TMDB Trademark Claims Services for Registrars

5.3.5.1.  Claims Notice Information Service (CNIS)

   The TCNs are provided by the TMDB online and are fetched by the
   Registrar via the dr interface (Section 4.3.6).

   To get access to the TCNs, the Registrar needs the credentials
   provided by the TMDB (Section 5.1.2.1) and the lookup key received
   from the Registry via the ry interface (Section 4.3.5).  The dr
   interface (Section 4.3.6) uses HTTPS with Basic access
   authentication.

   The dr interface (Section 4.3.6) MAY support up to ten (10)
   concurrent connections from each Registrar.

   The URL of the dr interface (Section 4.3.6) is:

      https://<tmdb-domain-name>/cnis/<lookupkey>.xml

   Note that the "lookupkey" may contain slash characters ("/").  The
   slash character is part of the URL path and MUST NOT be escaped when
   requesting the TCN.

   The TLS certificate (HTTPS) used on the dr interface (Section 4.3.6)
   MUST be signed by a well-know public CA.  Registrars MUST perform the
   certification path validation described in Section 6 of [RFC5280].
   Registrars will be authenticated in the dr interface using HTTP Basic
   access authentication.  The dr interface (Section 4.3.6) MUST support
   HTTPS keep-alive and MUST maintain the connection for up to 30
   minutes.

5.4.  Qualified Launch Program (QLP) Period

5.4.1.  Domain Registration

   During the OPTIONAL Qualified Launch Program (QLP) Period (see
   [QLP-Addendum]), effective allocations of DNs to third parties could
   require that Registries and Registrars provide Sunrise and/or
   Trademark Claims services.  If required, Registries and Registrars
   MUST provide Sunrise and/or Trademark Claims services, as described
   in Sections 5.2 and 5.3.

   The effective allocation scenarios are as follows:

   *  If the leftmost DNL of the DN being effectively allocated (QLP
      Name in this section) matches a DNL in the SURL and an SMD is
      provided, then Registries MUST provide Sunrise Services (see
      Section 5.2), and the DN MUST be reported in a Sunrise LORDN file
      during the QLP Period.  For example, if the DN "xn--mgbachtv.xn--
      mgbh0fb" is being effectively allocated, the leftmost DNL would be
      "xn--mgbachtv".

   *  If the QLP Name matches a DNL in the SURL but does not match a DNL
      in the DNL List and an SMD is NOT provided (see Section 2.2 of
      [QLP-Addendum]), then the DN MUST be reported in a Sunrise LORDN
      file using the special SMD-id "99999-99999" during the QLP Period.

   *  If the QLP Name matches a DNL in the SURL and also matches a DNL
      in the DNL List and an SMD is NOT provided (see Section 2.2 of
      [QLP-Addendum]), then Registries MUST provide Trademark Claims
      services (see Section 5.3), and the DN MUST be reported in a
      Trademark Claims LORDN file during the QLP Period.

   *  If the QLP Name matches a DNL in the DNL List but does not match a
      DNL in the SURL, then Registries MUST provide Trademark Claims
      services (see Section 5.3), and the DN MUST be reported in a
      Trademark Claims LORDN file during the QLP Period.

   The following table lists all the effective allocation scenarios
   during a QLP Period:

6.  Data Format Descriptions

6.1.  Domain Name Label (DNL) List

   This section defines the format of the list containing every DNL that
   matches a Pre-Registered Mark (PRM).  The list is maintained by the
   TMDB and downloaded by Registries in regular intervals (see
   Section 5.3.3.1).  The Registries use the DNL List during the
   Trademark Claims Period to check whether a requested DN matches a DNL
   of a PRM.

   The DNL List contains all the DNLs covered by a PRM present in the
   TMDB at the datetime that the DNL List is generated.

   The DNL List is contained in a CSV-formatted file that has the
   following structure:

   *  first line: <version>,<DNL List creation datetime>

         Where:

         o  <version>: version of the file.  This field MUST be 1.

         o  <DNL List creation datetime>: date and time in UTC that the
            DNL List was created.

   *  second line: a header line, as specified in [RFC4180]

         With the header names as follows:

         DNL,lookup-key,insertion-datetime

   *  One or more lines with: <DNL>,<lookup key>,<DNL insertion
      datetime>

         Where:

         o  <DNL>: a Domain Name Label covered by a PRM.

         o  <lookup key>: lookup key that the Registry MUST provide to
            the Registrar.  The lookup key has the following format:
            <YYYY><MM><DD><vv>/<X>/<X>/<X>/<Random bits><Sequential
            number>, where:

            +  YYYY: year that the TCN was generated.

            +  MM: zero-padded month that the TCN was generated.

            +  DD: zero-padded day that the TCN was generated.

            +  vv: version of the TCN; possible values are 00 and 01.

            +  X: one hex character.  This is the first, second, and
               third hex character of encoding the <Random bits> in
               base16, as specified in [RFC4648].

            +  Random bits: 144 random bits encoded in base64url, as
               specified in [RFC4648].

            +  Sequential number: zero-padded natural number in the
               range 0000000001 to 2147483647.

         o  <DNL insertion datetime>: datetime in UTC that the DNL was
            first inserted into the DNL List.  The possible two values
            of time for inserting a DNL to the DNL List are 00:00:00 and
            12:00:00 UTC.

   To provide authentication and integrity protection, the DNL List will
   be PGP [RFC4880] signed by the TMDB (see Section 5.1.1.4).  The PGP
   signature of the DNL List can be found in the similar URI but with
   extension .sig, as shown below.

   The URLs of the dy interface (Section 4.3.3) are:

   *  https://<tmdb-domain-name>/dnl/dnl-latest.sig

6.2.  SMD Revocation List

   This section defines the format of the list of SMDs that have been
   revoked.  The list is maintained by the TMDB and downloaded by
   Registries (and optionally by Registrars) in regular intervals (see
   Section 5.2.3.1).  The SMD Revocation List is used during the Sunrise
   Period to validate SMDs received.  The SMD Revocation List has a
   similar function as CRLs used in PKI [RFC5280].

   The SMD Revocation List contains all the revoked SMDs present in the
   TMDB at the datetime it is generated.

   The SMD Revocation List is contained in a CSV-formatted file that has
   the following structure:

   *  first line: <version>,<SMD Revocation List creation datetime>

         Where:

         o  <version>: version of the file.  This field MUST be 1.

         o  <SMD Revocation List creation datetime>: datetime in UTC
            that the SMD Revocation List was created.

   *  second line: a header line, as specified in [RFC4180]

         With the header names as follows:

         smd-id,insertion-datetime

   *  One or more lines with: <smd-id>,<revoked SMD datetime>

         Where:

         o  <smd-id>: identifier of the SMD that was revoked.

         o  <revoked SMD datetime>: revocation datetime in UTC of the
            SMD.  The possible two values of time for inserting an SMD
            to the SMD Revocation List are 00:00:00 and 12:00:00 UTC.

   To provide integrity protection, the SMD Revocation List is PGP
   signed by the TMDB (see Section 5.1.1.4).  The SMD Revocation List is
   provided by the TMDB with extension .csv.  The PGP signature of the
   SMD Revocation List can be found in the similar URI but with
   extension .sig, as shown below.

   The URLs of the sr interface (Section 4.3.12) and sy interface
   (Section 4.3.11) are:

6.3.  List of Registered Domain Names (LORDN) File

   This section defines the format of the List of Registered Domain
   Names (LORDN), which is maintained by each Registry and uploaded at
   least daily to the TMDB.  Every time there is a DN matching a DNL of
   a PRM, said DN is added to the LORDN, along with further information
   related to its registration.

   The URIs of the yd interface (Section 4.3.7) used to upload the LORDN
   file are:

   *  Sunrise LORDN file:

      https://<tmdb-domain-name>/LORDN/<TLD>/sunrise

   *  Trademark Claims LORDN file:

      https://<tmdb-domain-name>/LORDN/<TLD>/claims

   During a QLP Period, Registries MAY be required to upload Sunrise or
   Trademark Claims LORDN files.  The URIs of the yd interface used to
   upload LORDN files during a QLP Period are:

   *  Sunrise LORDN file (during QLP Period):

      https://<tmdb-domain-name>/LORDN/<TLD>/sunrise/qlp

   *  Trademark Claims LORDN file (during a QLP Period):

      https://<tmdb-domain-name>/LORDN/<TLD>/claims/qlp

   The yd interface (Section 4.3.7) returns the following HTTP status
   codes after an HTTP POST request method is received:

   *  The interface provides an HTTP/202 status code if the interface
      was able to receive the LORDN file and the syntax of the LORDN
      file is correct.

      The interface provides the LORDN Transaction Identifier in the
      HTTP Entity-body that would be used by the Registry to download
      the LORDN Log file.  The LORDN Transaction Identifier is a zero-
      padded natural number in the range 0000000000000000001 to
      9223372036854775807.

      The TMDB uses the <LORDN creation datetime> element of the LORDN
      file as a unique client-side identifier.  If a LORDN file with the
      same <LORDN creation datetime> of a previously sent LORDN file is
      received by the TMDB, the LORDN Transaction Identifier of the
      previously sent LORDN file MUST be provided to the Registry.  The
      TMDB MUST ignore the DN Lines present in the LORDN file if a LORDN
      file with the same <LORDN creation datetime> was previously sent.

      The HTTP Location header field contains the URI where the LORDN
      Log file could be retrieved later, for example:

         202 Accepted

         Location: https://<tmdb-domain-
         name>/LORDN/example/sunrise/0000000000000000001/result

   *  The interface provides an HTTP/400 if the request is incorrect or
      the syntax of the LORDN file is incorrect.  The TMDB MUST return a
      human-readable message in the HTTP Entity-body regarding the
      incorrect syntax of the LORDN file.

   *  The interface provides an HTTP/401 status code if the credentials
      provided do not authorize the Registry Operator to upload a LORDN
      file.

   *  The TMDB MUST return an HTTP/404 status code when trying to upload
      a LORDN file using the https://<tmdb-domain-
      name>/LORDN/<TLD>/sunrise/qlp or https://<tmdb-domain-
      name>/LORDN/<TLD>/claims/qlp interface outside of a QLP Period
      plus 26 hours.

   *  The interface provides an HTTP/500 status code if the system is
      experiencing a general failure.

   For example, to upload the Sunrise LORDN file for TLD "example", the
   URI would be:

      https://<tmdb-domain-name>/LORDN/example/sunrise

   The LORDN is contained in a CSV-formatted file that has the following
   structure:

   *  For Sunrise Period:

      -  first line: <version>,<LORDN creation datetime>,<Number of DN
         Lines>

            Where:

            +  <version>: version of the file.  This field MUST be 1.

            +  <LORDN creation datetime>: date and time in UTC that the
               LORDN was created.

            +  <Number of DN Lines>: number of DN Lines present in the
               LORDN file.

      -  second line: a header line, as specified in [RFC4180]

            With the header names as follows:

            roid,domain-name,SMD-id,registrar-id,registration-
            datetime,application-datetime

      -  One or more lines with: <roid>,<DN registered>,<SMD-id>,<IANA
         Registrar id>,<datetime of registration>,<datetime of
         application creation>

            Where:

            +  <roid>: DN Repository Object IDentifier (DNROID) in the
               SRS.

            +  <DN registered>: DN that was effectively allocated.  For
               IDNs, the A-label form is used.

            +  <SMD-id>: SMD ID used for registration.

            +  <IANA Registrar ID>: IANA Registrar ID.

            +  <datetime of registration>: date and time in UTC that the
               domain was effectively allocated.

            +  OPTIONAL <datetime of application creation>: date and
               time in UTC that the application was created.  The
               <datetime of application creation> MUST be provided in
               case of a DN effective allocation based on an
               asynchronous registration (e.g., when using auctions).

            datetime,ack-datetime,application-datetime

      -  One or more lines with: <roid>,<DN registered>,<TCNID>,<IANA
         Registrar id>,<datetime of registration>,<datetime of
         acceptance of the TCN>,<datetime of application creation>

            Where:

            +  <roid>: DNROID in the SRS.

            +  <DN registered>: DN that was effectively allocated.  For
               IDNs, the A-label form is used.

            +  <TCNID>: Trademark Claims Notice Identifier, as specified
               in <tmNotice:id>.

            +  <IANA Registrar ID>: IANA Registrar ID.

            +  <datetime of registration>: date and time in UTC that the

6.3.1.  LORDN Log File

   After reception of the LORDN file, the TMDB verifies its content for
   syntactical and semantic correctness.  The output of the LORDN file
   verification is retrieved using the yd interface (Section 4.3.7).

   The URIs of the yd interface (Section 4.3.7) used to retrieve the
   LORDN Log file are:

   *  Sunrise LORDN Log file:

      https://<tmdb-domain-name>/LORDN/<TLD>/sunrise/<lordn-transaction-
      identifier>/result

   *  Trademark Claims LORDN Log file:

      https://<tmdb-domain-name>/LORDN/<TLD>/claims/<lordn-transaction-
      identifier>/result

   A Registry Operator MUST NOT send more than one request per minute
   per TLD to download a LORDN Log file.

   The yd interface (Section 4.3.7) returns the following HTTP status
   codes after an HTTP GET request method is received:

   *  The interface provides an HTTP/200 status code if the interface
      was able to provide the LORDN Log file.  The LORDN Log file is
      contained in the HTTP Entity-body.

   *  The interface provides an HTTP/204 status code if the LORDN
      Transaction Identifier is correct but the server has not finalized
      processing the LORDN file.

   *  The interface provides an HTTP/400 status code if the request is
      incorrect.

   *  The interface provides an HTTP/401 status code if the credentials
      provided do not authorize the Registry Operator to download the
      LORDN Log file.

   *  The interface provides an HTTP/404 status code if the LORDN
      Transaction Identifier is incorrect.

   *  The interface provides an HTTP/500 status code if the system is
      experiencing a general failure.

   For example, to obtain the LORDN Log file in case of a Sunrise LORDN
   file with LORDN Transaction Identifier 0000000000000000001 and TLD
   "example", the URI would be:

      https://<tmdb-domain-
      name>/LORDN/example/sunrise/0000000000000000001/result

   The LORDN Log file is contained in a CSV-formatted file that has the
   following structure:

   *  first line: <version>,<LORDN Log creation datetime>,<LORDN file
      creation datetime>,<LORDN Log Identifier>,<Status flag>,<Warning
      flag>,<Number of DN Lines>

         Where:

         o  <version>: version of the file.  This field MUST be 1.

         o  <LORDN Log creation datetime>: date and time in UTC that the
            LORDN Log was created.

         o  <LORDN file creation datetime>: date and time in UTC of
            creation for the LORDN file that this log file is referring
            to.

         o  <LORDN Log Identifier>: unique identifier of the LORDN Log
            provided by the TMDB.  This identifier could be used by the
            Registry Operator to unequivocally identify the LORDN Log.
            The identified will be a string of a maximum length of 60
            characters from the base64 alphabet.

         o  <Status flag>: whether the LORDN file has been accepted for
            processing by the TMDB.  Possible values are "accepted" or
            "rejected".

         o  <Warning flag>: whether the LORDN Log has any warning result
            codes.  Possible values are "no-warnings" or "warnings-
            present".

         o  <Number of DN Lines>: number of DN effective allocations
            processed in the LORDN file.

         A Registry Operator is not required to process a LORDN Log with
         <Status flag>="accepted" and <Warning flag>="no-warnings".

   *  second line: a header line, as specified in [RFC4180]

         With the header names as follows:

         roid,result-code

   *  One or more lines with: <roid>,<result code>

         Where:

         o  <roid>: DNROID in the SRS.

         o  <result code>: result code, as described in Section 6.3.1.1.

   Example of a LORDN Log file:

6.3.1.1.  LORDN Log Result Codes

   The classes of result codes (rc) are listed below.  The classes in
   square brackets are not used at this time but may come into use at
   some later stage.  The first two digits of a result code denote the
   result code class, which defines the outcome at the TMDB:

   *  ok: Success.  The DN Line is accepted by the TMDB.

   *  warn: A warning is issued.  The DN Line is accepted by the TMDB.

   *  err: An error is issued.  The LORDN file is rejected by the TMDB.

   In cases where a DN line is processed and the error result code is
   45xx or 46xx, the LORDN file MUST be rejected by the TMDB.  If the
   LORDN file is rejected, DN Lines that are syntactically valid will be
   reported with a 2001 result code.  A 2001 result code means that the
   DN Line is syntactically valid; however, the DN Line was not
   processed because the LORDN file was rejected.  All DNs reported in a
   rejected LORDN file MUST be reported again by the Registry because
   none of the DN Lines present in the LORDN file have been processed by
   the TMDB.

   LORDN Log Result Code Classes:

              +======+============================+=========+
              | Code | Class                      | Outcome |
              +======+============================+=========+
              | 20xx | Success                    | ok      |
              +------+----------------------------+---------+
              | 35xx | [ DN Line syntax warning ] | warn    |
              +------+----------------------------+---------+
              | 36xx | DN Line semantic warning   | warn    |
              +------+----------------------------+---------+
              | 45xx | DN Line syntax error       | err     |
              +------+----------------------------+---------+
              | 46xx | DN Line semantic error     | err     |

6.4.  Signed Mark Data (SMD) File

   This section defines the format of the SMD File.  After a successful
   registration of a mark, the TMV returns an SMD File to the TMH.  The
   SMD File can then be used for registration of one or more DNs covered
   by the PRM during the Sunrise Period of a TLD.

   Two encapsulation boundaries are defined for delimiting the
   encapsulated base64-encoded SMD: "-----BEGIN ENCODED SMD-----" and "
   -----END ENCODED SMD-----".  Only data inside the encapsulation
   boundaries MUST be used by Registries and Registrars for validation
   purposes, i.e., any data outside these boundaries as well as the
   boundaries themselves MUST be ignored for validation purposes.

   The structure of the SMD File is as follows.  All the elements are
   REQUIRED and MUST appear in the specified order.

   1.  Marks: <marks>

   2.  smdID: <SMD-ID>

   3.  U-labels: <comma separated list of U-label or NR-LDH labels (see
       [RFC5890])>

   4.  notBefore: <begin validity>

   5.  notAfter: <end validity>

   6.  -----BEGIN ENCODED SMD-----

   7.  <encoded SMD (see [RFC7848])>

   8.  -----END ENCODED SMD-----

   Example of an SMD file:

   Marks: Example One
   smdID: 1-2
   U-labels: example-one, exampleone
   notBefore: 2011-08-16 09:00
   notAfter: 2012-08-16 09:00

6.5.  Trademark Claims Notice (TCN)

   The TMDB MUST provide the TCN to Registrars in XML format, as
   specified below.

   The enclosing element <tmNotice:notice> describes the Trademark
   Notice to a given label.

   The child elements of the <tmNotice:notice> element include:

   *  A <tmNotice:id> element that contains the unique identifier of the
      Trademark Notice.  This element contains the TCNID.

         The TCNID is a string concatenation of a TCN Checksum and the
         TMDB Notice Identifier.  The first 8 characters of the TCNID is
         a TCN Checksum.  The rest is the TMDB Notice Identifier, which
         is a zero-padded natural number in the range of
         0000000000000000001 to 9223372036854775807.

         Example of a TCNID:

            370d0b7c9223372036854775807.

         Where:

         o  TCN Checksum=370d0b7c

         o  TMDB Notice Identifier=9223372036854775807

         The TCN Checksum is an 8-character-long base16-encoded output
         of computing the CRC32 of the string concatenation of: label +
         unix_timestamp(<tmNotice:notAfter>) + TMDB Notice Identifier.

         The TMDB MUST use the Unix time conversion of the
         <tmNotice:notAfter> in UTC to calculate the TCN Checksum.  Unix
         time is defined as the number of seconds that have elapsed
         since 1970-01-01T00:00:00Z, not counting leap seconds.  For
         example, the conversion of 2010-08-16T09:00:00.0Z to Unix time
         is:

            unix_time(2010-08-16T09:00:00.0Z)=1281949200

         The TMDB uses the <tmNotice:label> and <tmNotice:notAfter>
         elements from the TCN along with the TMDB Notice Identifier to
         compute the TCN Checksum.

         A Registry MUST use the leftmost DNL of the DN being
         effectively allocated, the expiration datetime of the TCN
         (provided by the Registrar), and the TMDB Notice Identifier
         extracted from the TCNID (provided by the Registrar) to compute
         the TCN Checksum.  For example, if the DN "xn--mgbachtv.xn--
         mgbh0fb" is being effectively allocated, the leftmost DNL would
         be "xn--mgbachtv".

         An example computation of the TCN Checksum is:

            CRC32(example-one12819492009223372036854775807)=370d0b7c

   *  A <tmNotice:notBefore> element that contains the start of the
      valid date and time of the TCN.

   *  A <tmNotice:notAfter> element that contains the expiration date
      and time of the TCN.

   *  A <tmNotice:label> element that contains the DNL covered by a PRM.

   *  One or more <tmNotice:claim> elements that contain the Trademark
      Claims.  The <tmNotice:claim> element contains the following child
      elements:

      -  A <tmNotice:markName> element that contains the mark text
         string.

      -  One or more <tmNotice:holder> elements that contain the
         information of the holder of the mark.  An "entitlement"
         attribute is used to identify the entitlement of the holder;
         possible values are: owner, assignee, or licensee.  The child
         elements of <tmNotice:holder> include:

         o  An OPTIONAL <tmNotice:name> element that contains the name
            of the holder. <tmNotice:name> MUST be specified if
            <tmNotice:org> is not specified.

         o  An OPTIONAL <tmNotice:org> element that contains the name of
            the organization holder of the mark. <tmNotice:org> MUST be
            specified if <tmNotice:name> is not specified.

         o  A <tmNotice:addr> element that contains the address
            information of the holder of a mark. <tmNotice:addr>
            contains the following child elements:

            +  One, two, or three OPTIONAL <tmNotice:street> elements
               that contain the organization's street address.

            +  A <tmNotice:city> element that contains the
               organization's city.

            +  An OPTIONAL <tmNotice:sp> element that contains the
               organization's state or province.

            +  An OPTIONAL <tmNotice:pc> element that contains the
               organization's postal code.

            +  A <tmNotice:cc> element that contains the organization's
               country code.  This a two-character code from
               [ISO3166-2].

         o  An OPTIONAL <tmNotice:voice> element that contains the
            organization's voice telephone number.

         o  An OPTIONAL <tmNotice:fax> element that contains the
            organization's facsimile telephone number.

         o  An OPTIONAL <tmNotice:email> element that contains the email
            address of the holder.

      -  Zero or more OPTIONAL <tmNotice:contact> elements that contain
         the information of the representative of the mark registration.
         A "type" attribute is used to identify the type of contact;
         possible values are: owner, agent, or third party.  The child
         elements of <tmNotice:contact> include:

         o  A <tmNotice:name> element that contains the name of the
            responsible person.

         o  An OPTIONAL <tmNotice:org> element that contains the name of
            the organization of the contact.

         o  A <tmNotice:addr> element that contains the address
            information of the contact.  <tmNotice:addr> contains the
            following child elements:

            +  One, two, or three OPTIONAL <tmNotice:street> elements
               that contain the contact's street address.

            +  A <tmNotice:city> element that contains the contact's
               city.

            +  An OPTIONAL <tmNotice:sp> element that contains the
               contact's state or province.

            +  An OPTIONAL <tmNotice:pc> element that contains the
               contact's postal code.

            +  A <tmNotice:cc> element that contains the contact's
               country code.  This a two-character code from
               [ISO3166-2].

         o  A <tmNotice:voice> element that contains the contact's voice

6.6.  Sunrise List (SURL)

   This section defines the format of the list containing every DNL that
   matches a PRM eligible for Sunrise.  The list is maintained by the
   TMDB and downloaded by Registries in regular intervals (see
   Section 5.4.2.1).  The Registries use the Sunrise List during the QLP
   Period to check whether a requested DN matches a DNL of a PRM
   eligible for Sunrise.

   The Sunrise List contains all the DNLs covered by a PRM eligible for
   Sunrise that are present in the TMDB at the datetime it is generated.

   The Sunrise List is contained in a CSV-formatted file that has the
   following structure:

   *  first line: <version>,<Sunrise List creation datetime>

         Where:

         o  <version>: version of the file.  This field MUST be 1.

         o  <Sunrise List creation datetime>: date and time in UTC that
            the Sunrise List was created.

   *  second line: a header line, as specified in [RFC4180]

         With the header names as follows:

         DNL,insertion-datetime

   *  One or more lines with: <DNL>,<DNL insertion datetime>

         Where:

         o  <DNL>: a Domain Name Label covered by a PRM eligible for
            Sunrise.

         o  <DNL insertion datetime>: datetime in UTC that the DNL was
            first inserted into the Sunrise List.  The possible two
            values of time for inserting a DNL to the Sunrise List are
            00:00:00 and 12:00:00 UTC.

   Example of a Sunrise List:

   1,2012-08-16T00:00:00.0Z
   DNL,insertion-datetime
   example,2010-07-14T00:00:00.0Z
   another-example,2012-08-16T00:00:00.0Z
   anotherexample,2011-08-16T12:00:00.0Z

                      Figure 17: Example Sunrise List

   To provide authentication and integrity protection, the Sunrise List
   will be PGP signed by the TMDB (see Section 5.1.1.4).  The PGP
   signature of the Sunrise List can be found in the similar URI but
   with extension .sig, as shown below.

   The URLs of the dy interface (Section 4.3.3) are:

   *  https://<tmdb-domain-name>/dnl/surl-latest.csv

   *  https://<tmdb-domain-name>/dnl/surl-latest.sig

8.  IANA Considerations

   The code point assigned in support of this document is taken from the
   wrong point in the registration tree.  Unfortunately, the code point
   has already been deployed in the field without following the proper
   registration review process.  The designated experts for the registry
   have considered the issues that correcting this action would cause
   for deployed implementations and have consented to the continued use
   of the code point.

   This document uses URNs to describe XML namespaces and XML schemas
   conforming to a registry mechanism described in [RFC3688].  IANA has
   registered two URI assignments as follows.

   Trademark Claims Notice namespace:

   URI:  urn:ietf:params:xml:ns:tmNotice-1.0
   Registrant Contact:  IETF <iesg@ietf.org> and ICANN
      <globalsupport@icann.org>
   XML:  None.  Namespace URIs do not represent an XML specification.
   Note:  Note that this assignment is made from the wrong point in the
      tree in order to be consistent with deployed implementations.

   Trademark Claims Notice XML schema:

   URI:  urn:ietf:params:xml:schema:tmNotice-1.0
   Registrant Contact:  IETF <iesg@ietf.org> and ICANN
      <globalsupport@icann.org>
   XML:  See Section 7.1 of RFC 9361.
   Note:  Note that this assignment is made from the wrong point in the
      tree in order to be consistent with deployed implementations.

9.  Security Considerations

   This specification uses HTTP Basic Authentication to provide a simple
   application-layer authentication service.  HTTPS is used in all
   interfaces in order to protect against most common attacks.  In
   addition, the client identifier is tied to a set of IP addresses that
   are allowed to connect to the interfaces described in this document,
   providing an extra security measure.

   The TMDB MUST provide credentials to the appropriate Registries and
   Registrars.

   The TMDB MUST require the use of strong passwords by Registries and
   Registrars.

   The TMDB, Registries, and Registrars MUST use the best practices
   described in [RFC9325] or its successors.

10.  Privacy Considerations

   This specification defines the interfaces to support the
   [RPM-Requirements].  Legal documents govern the interactions between
   the different parties, and such legal documents must ensure that
   privacy-sensitive and/or personal data receives the required
   protection.
