1. Introduction
Second-level Node (SLN) Data Escrow is the process by which an SLN
periodically submits data deposits to a third-party called an escrow
Wu, et al. Expires December 21, 2021 [Page 2]
Internet-Draft IIIN-Data-Escrow June 2021
agent. These deposits comprise the minimum data needed by a third-
party to resume operations if the SLN cannot function and is unable
or unwilling to facilitate an orderly transfer of service.
The goal of data escrow is higher resiliency of registration
services, for the benefit of Internet users. The beneficiaries of a
SLN are not just those registering information there, but all
relying parties that need to identify the owners of objects.
This document defines the data escrow structure of the standard set
of objects for Industrial Internet Identifier Nodes which include
Second-level Node (SLN) and Enterprise-level Node (ELN).
This document defines the following object:
o Node: Including the enterprise registration information of the
SLN and the ELN registered in SLN.
This document defines the following pseudo-object:
o Header: Used to specify counters of objects in the database at a
certain point in time (watermark).
In the context of industry identifier namespace, data escrow is a
requirement for SLN. There is also a similar requirement for SLN
accredited identifier registration node.
This document specifies a format for data escrow deposits
independent of the objects being escrowed. A specification is
required for each type of registry/set of objects that is expected
to be escrowed.
2. Model
This document defines XML model be used to deposit data escrow
objects. The XML model includes all the deposit information (meta-
data and data) in an XML document. The definition of the XML format
is fully defined in the XML schemas. As a convention, the objects
represented using the XML model are referenced using INDE and an XML
namespace that is prefixed with "inde". For example, the SLN
enterprise registration information represented using the XML model
can be referred to as the INDE Node with the XML namespace including
indeNode (urn:ietf:params:xml:ns:indeNode-1.0).

3. Conventions used in this document
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.
SECOND-LEVEL NODE (SLN). In the context of this draft the definition
will indicate an organization providing Registry Services for a
second level identifier.
REGISTRY SERVICES. Services offered by the SLN critical to the
following tasks: responding to enterprise node queries for status
information relating to the servers for identifier; responding to
queries for enterprise information concerning identifier
registrations in the SLN. Any other products or services that only
an SLN is capable of providing by reason of its designation as a
SLN. Typical example of Services is: Identifier Resolving.
4. General Conventions
4.1. Date and Time
Numerous fields indicate "dates", such as the creation and expiry
dates for objects. These fields SHALL contain timestamp indicating
the date and time in UTC, specified in Internet Date/Time Format
(see [RFC3339], Section 5.6) with the time-offset specified as "Z".
4.2. IP Address
The syntax for IPv4 addresses described in this document MUST
conform to [RFC5730]. The syntax for IPv6 addresses described in
this document MUST conform to [RFC4291]. Practical considerations
for publishing IPv6 address information in zone files are documented
in [RFC2874] and [RFC3596]. A server MAY reject IP addresses that
have not been allocated for public use by IANA.
4.3. Country names
Country identifiers SHALL be represented using two characters
identifiers as specified in [ISO-3166-1].
4.4. Telephone numbers
Telephone numbers (both voice and facsimile) SHALL be formatted
based on structures defined in [ITU-E164]. Telephone numbers
Wu, et al. Expires December 21, 2021 [Page 4]
Internet-Draft IIIN-Data-Escrow June 2021
described in this specification are character strings that MUST
begin with a plus sign ("+", ASCII value 0x002B), followed by a
country code defined in [ITU-E164], followed by a dot (".", ASCII
value 0x002E), followed by a sequence of digits representing the
telephone number.
4.5. Internationalized and Localized Elements
Some elements MAY be provided in either internationalized form
("int") or provided in localized form ("loc"). This MAY override the
form specified for a parent element. A value of "int" is used to
indicate the internationalized form and a value of "loc" is used to
indicate the localized form. When the internalized form ("int") is
provided, the field value MUST be represented in a subset of UTF-8
that can be represented in the 7-bit US-ASCII character set. When
the localized form ("loc") is provided, the field value MAY be
represented in unrestricted UTF-8.
5. Object Description
This section describes the base objects supported by this
specification:
5.1. Node Object
The node object represents the enterprise registration information
of a Second-level Node or Enterprise-level Node, and this element
supports XML Model.
5.1.1. XML Model
There are two elements used in the data escrow in the node objects
of the XML model including the <indeNode:node>, under the
<inde:contents> element, and the <indeNode:delete> element, under
the <inde:deletes> element.
A <indeNode:node> element substitutes for the
<indeNode:abstractNode> abstract element to define a concrete
definition of a identifier node. The <indeNode:abstractNode> element
can be replaced by other node definitions using the XML schema
substitution groups feature.
5.1.1.1. <indeNode:node> element
The <node> element contains a "type" attribute to identify the node
is a Second-level Node or Enterprise-level Node. If a Second-level
Node (type="sec") is provided, element content MUST be Second-level
Wu, et al. Expires December 21, 2021 [Page 5]
Internet-Draft IIIN-Data-Escrow June 2021
Node information. If an Enterprise-level Node (type="ent") is
provided, element content be Enterprise-level Node information. The
<node> element contains the following child elements:
o A <prefix> element contains the node-unique identifier of the
node object.
o A <name> element contains the name of the enterprise.
o A <nature> element contains the enterprise nature.
o An <addr> element contains the enterprise address information.
This element content MUST be represented in a subset of UTF-8
that can be represented in the 7-bit US-ASCII character set. The
<addr> element contains the following child elements:
One, or two OPTIONAL <street> elements contain the enterprise's
street address
A <city> element contains the enterprise's city.
An OPTIONAL <sp> element contains the enterprise's state or
province.
A <cc> element contains the enterprise's two-letter country
code.
o Zero or more <ipAddr> elements that contain enterprise's IP
address. The <ipAddr> element contains the following child
elements:
An <ip> element contains the IP address.
A <port> element contains the network port.
o A <cred> element. A required "type" attribute is used to identify
the credentials owner: Enterprise or Enterprise Legal Person. If
a (type="ent") is provided, element content MUST be enterprise's
credentials type. If a (type="leg") is provided, element content
MUST be enterprise's legal person credentials type. The <cred>
element contains the following child elements:
A <credType> element contains the credentials Type.
A <credNo> element contains the credentials Number.
o A <legName> element contains the enterprise legal person Name.

o A <contact> element contains the enterprise's contact
information. The <contact> element contains the following child
elements:
A <name> element contains the contact name.
A <phone> element that contains the contact phone.
A <email> element that contains the contact email address.
o A <crDate> element contains the enterprise's node register date.
o Zero or One <upDate> element contains the enterprise's node

5.1.1.2. <indeNode:delete> object
The <indeNode:delete> element contains the SLN identifier that was
deleted.
Example of <indeNode:delete> object:
...
<inde:deletes>
...

</indeNode:delete>
<indeNode:delete>
<indeNode:prefix>86.200.1</indeNode:prefix>
</indeNode:delete>
...
</inde:deletes>
...
5.2. Header Object
The Header Object is a pseudo-object that is used to specify the
number of objects in the repository at a specific point in time
(watermark) regardless of the type of deposit: differential or full.
The Header Object may also be used to provide additional information
Wu, et al. Expires December 21, 2021 [Page 9]
Internet-Draft IIIN-Data-Escrow June 2021
on the contents of the deposit. The Header Object is only defined as
XML, but one header object MUST always be present per escrow deposit
regardless of using XML Model. The Header Object is defined using
the <indeHeader:header> element.
5.2.1. <indeHeader:header> object
The <indeHeader:header> contains the following elements:
o A choice of one of the elements defined in the
"repositoryTypeGroup" group element that indicates the unique
identifier for the repository being escrowed. Possible elements:
A <indeHeader:slnp> element that defines Second-level Node
Prefix being escrowed.
A <indeHeader:node> element that defines Enterprise-level Node
prefix registered in Second-level.
A <indeHeader:reseller> element that defines the provider ID
corresponding to a Reseller data escrow deposit.
o A <count> element that contains the number of objects in the SLN
System at a specific point in time (watermark) regardless of the
type of deposit: differential or full. The <count> element
supports the following attributes:
An "uri" attribute to reflect the XML namespace URI of the
primary objects of the XML Model. For example, the "uri" is set
to "urn:ietf:params:xml:ns:indeNode-1.0" for Node objects using
the XML Model.
An OPTIONAL "inp" attribute indicates the identifier node
prefix of the object included in the <count> element.
o An PTIONAL <contentTag> element that contains a tag that defines
the expected content in the deposit. The producer and consumer of
the deposits will coordinate the set of possible <contentTag>
element values
Example of <indeHeader:header> object referencing only the XML Model
objects:
...
<indeHeader:header>
Wu, et al. Expires December 21, 2021 [Page 10]
Internet-Draft IIIN-Data-Escrow June 2021
<indeHeader:slnp>86.200</indeHeader:slnp>
<indeHeader:count
uri="urn:ietf:params:xml:ns:indeNode-1.0">2
</indeHeader:count>
</indeHeader:header>
...
6. Profile
Different business models of SLN exist, therefore the SLN is
responsible to define a profile that matches its particular business
model. The profile mechanism allows an SLN to extend this
specification.
A profile is the process of:
o Extending base objects with the mechanisms defined for XML model.
For XML model, abstract elements could be used to extend the
object <node> using XML schema substitution groups feature.
o Adding new escrowed objects using the <inde:contents> and
<inde:deletes> elements.
o Providing the XML schemas to third parties that require them to
validate the escrow deposits.
7. Data escrow agent extended verification process
A Data Escrow Agent SHOULD perform an extended verification process
that starts by creating a dataset to be tested.
o If a full deposit is to be tested, the full deposit is the
dataset.
o If a differential deposit is to be tested, the dataset is created
by using the differential deposit plus all the required deposits
leading to the last previous full deposit.
The following are the minimum suggested tests on the dataset:
Wu, et al. Expires December 21, 2021 [Page 11]
Internet-Draft IIIN-Data-Escrow June 2021
o Validate the escrow deposits using the definition agreed with the
SLN.
In the case of the XML model, the contents of the escrow
deposits MUST be validated using the XML schemas of the
profile.
o Count the objects and validate that the number of objects is
equal to the number objects reported in the <header> element of
the escrow deposit of that point in time (watermark).
o The elements listed as required in the <policy> element MUST be
present.
o Providing the XML schemas to third parties that require them to
validate the escrow deposits.
o The watermark is not in the future.

9. Internationalization Considerations
Data escrow deposits are represented in XML, which provides native
support for encoding information using the Unicode character set and
its more compact representations including UTF-8. Conformant XML
processors recognize both UTF-8 and UTF-16. Though XML includes
provisions to identify and use other character encodings through use
of an "encoding" attribute in an <?xml?> declaration, use of UTF-8
is RECOMMENDED.
10. Security Considerations
This specification does not define the security mechanisms to be
used in the transmission of the data escrow deposits, since it only
specifies the minimum necessary to enable the rebuilding of an IIIN
from deposits without intervention from the original IIIN.
Depending on local policies, some elements or most likely, the whole
deposit will be considered confidential. As such the IIIN
transmitting the data to the escrow agent SHOULD take all the
Wu, et al. Expires December 21, 2021 [Page 23]
Internet-Draft IIIN-Data-Escrow June 2021
necessary precautions like encrypting the data itself and/or the
transport channel to avoid inadvertent disclosure of private data.
It is also of the utmost importance the authentication of the
parties passing data escrow deposit files. The escrow agent SHOULD
properly authenticate the identity of the IIIN before accepting data
escrow deposits. In a similar manner, the IIIN SHOULD authenticate
the identity of the escrow agent before submitting any data.
Additionally, the IIIN and the escrow agent SHOULD use integrity
checking mechanisms to ensure the data transmitted is what the
source intended. Validation of the contents by the escrow agent is
RECOMMENDED to ensure not only the file was transmitted correctly
from the IIIN, but also the contents are also "meaningful".
11. IANA Considerations
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688]. Four URI
assignments need to be registered by the IANA.
Registration request for the INDE namespace:
URI: urn:ietf:params:xml:ns:indeNode-1.0
URI: urn:ietf:params:xml:ns:indeHeader-1.0
Registrant Contact: See the "Author's Address" section of this
document.
XML: None. Namespace URIs do not represent an XML specification.
Registration request for the INDE XML schema:
URI: urn:ietf:params:xml:schema:indeNode-1.0
URI: urn:ietf:params:xml:schema:indeHeader-1.0
Registrant Contact: See the "Author's Address" section of this
document.
XML: See the "Formal Syntax" section of this document.
12. Privacy Considerations
This specification defines a format that may be used to escrow
personal data. The process of data escrow is governed by a legal
Wu, et al. Expires December 21, 2021 [Page 24]
Internet-Draft IIIN-Data-Escrow June 2021
document agreed by the parties, and such legal document must
regulate the particularities regarding the protection of personal
data.
