1. Introduction
This document describes responses in the JSON [RFC8259] format for
the queries as defined by the Industrial Internet Identifier Data
Access Protocol Query Format [IDENTIFIER-QUERY]. A communication
Ma, et al. Expires June 21, 2024 [Page 2]
Internet-Draft Identifier Data Response Protocol December 21, 2023
protocol for exchanging queries and responses is described in
[IDENTIFIER-HTTP].
1.1. Terminology and Definitions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
The following list describes terminology and definitions used
throughout this document:
TLN: Top-Level Nodes
SLN: Second-Level Nodes
ELN: Enterprise-Level Nodes
member: data found within an object as defined by JSON [RFC8259].
object: a data structure as defined by JSON [RFC8259].
IIIDAP: Industrial Internet Identifier Data Access Protocol
1.2. Data Model
The data model for JSON responses is specified in five sections:
1. simple data types conveyed in JSON strings
2. data structures specified as JSON arrays or objects that are used
repeatedly when building up larger objects
3. arrays of objects representing structured data corresponding to a
search for multiple objects
4. the response to an error
Positive responses take two forms. A response to a lookup of a
single object yields a JSON object, which is the subject of the
lookup. A response to a search for multiple objects yields a JSON
object that contains an array of JSON objects that are the subject
of the search. In each type of response, other data structures are
present within the topmost JSON object.
Ma, et al. Expires June 21, 2024 [Page 3]
Internet-Draft Identifier Data Response Protocol December 21, 2023
2. Use of JSON
2.1. Naming
Clients of these JSON responses SHOULD ignore unrecognized JSON
members in responses.
Clients processing JSON responses need to be prepared for members
representing identifier data specified in this document to be absent
from a response. In other words, servers are free to not include
JSON members containing identifier data based on their own policies.
Finally, all JSON names specified in this document are case
sensitive. Both servers and clients MUST transmit and process them
using the specified character case.
3. Common Data Types
JSON [RFC8259] defines the data types of a number, character string,
boolean, array, object, and null. This section describes the
semantics and/or syntax reference for common, JSON character strings
used in this document.
identifier: Take Handle Protocol [RFC3651] as an example,
Identifier format of TLN is XX; identifier format
of SLD is XX.YY; identifier format of ELD is
XX.YY.ZZ; XX, YY, ZZ are UTF-8 [RFC3629] encoded
character strings, which use any characters from
the Unicode 2.0 standard except the ASCII character
'/' (0x2F).
name: The maximum limit of name field is 255 ASCII
characters.
picture: Pictures need to be Base64 encoded, then
transferred via json.
id: The maximum limit of id field is 32 ASCII
characters.
country codes: Where the identity of a geopolitical nation or
country is needed, these identities are represented
with the alpha-2 or two-character country code
designation as defined in [ISO.3166.1988]. The
alpha-2 representation is used because it is freely
available, whereas the alpha-3 and numeric-3
standards are not.
Ma, et al. Expires June 21, 2024 [Page 4]
Internet-Draft Identifier Data Response Protocol December 21, 2023
dates and times: The syntax for values denoting dates and times is
defined in [RFC3339].
URIs: The syntax for values denoting a Uniform Resource
Identifier (URI) is defined by [RFC3986].
4. Common Data Structures
This section defines common data structures used in responses.
4.1. IIIDAP Conformance
The data structure named "iiidapConformance" is an array of strings,
each providing a hint as to the specifications used in the
construction of the response. This data structure appears only in
the topmost JSON object of a response.
An example iiidapConformance data structure:
"iiidapConformance" :
[
"iiidap_level_0"
]
Figure 1
The string literal "iiidap_level_0" signifies conformance with this
specification.
4.2. Links
The "links" array is found in data structures to signify links to
other resources on the Internet. The relationship of these links is
defined by the IANA registry described by [RFC8288].
The following is an example of the link structure:
{
"value" : "http://example.com/context_uri",
"rel" : "self",
"href" : "http://example.com/target_uri",
"hreflang" : [ "en", "ch" ],
Ma, et al. Expires June 21, 2024 [Page 5]
Internet-Draft Identifier Data Response Protocol December 21, 2023
"title" : "title",
"media" : "screen",
"type" : "application/json"
}
Figure 2
The JSON name/values of "rel", "href", "hreflang", "title", "media",
and "type" correspond to values found in Section 5 of [RFC8288]. The
"value" JSON value is the context URI as described by [RFC8288]. The
"href" JSON value MUST be specified. All other JSON values are
OPTIONAL.
This is an example of the "links" array as it might be found in an
notice:
"links" :
[
{
"href" : "http://example.com",
"title" : ""Terms of Use""
}
]
Figure 3
4.3. Notices and Remarks
The "notices" and "remarks" data structures take the same form. The
notices structure denotes information about the service providing
IIIDAP information and/or information about the entire response,
whereas the remarks structure denotes information about the
identifiers that contains it.
Both are arrays of objects. Each object contains an optional "title"
string representing the title of the object, an optional "type"
string denoting a registered type of remark or notice, an array of
strings named "description" for the purposes of conveying any
descriptive text, and an optional "links" array as described in
Section 4.2.
Ma, et al. Expires June 21, 2024 [Page 6]
Internet-Draft Identifier Data Response Protocol December 21, 2023
An example of the notices data structure:
"notices" :
[
{
"title" : "Terms of Use",
"description" :
[
"Service subject to The Registry of the Moon's TOS.",
"Copyright (c) 2020 LunarNIC"
],
"links" :
[
{
"value" : "http://example.net/entity/XXXX",
"rel" : "alternate",
"type" : "text/html",
"href" : http://www.example.com/terms_of_use.html
}
]
}
]
Figure 4
It is the job of the clients to determine line breaks, spacing, and
display issues for sentences within the character strings of the
"description" array. Each string in the "description" array contains a
single complete division of human-readable text indicating to clients
where there are semantic breaks.
An example of the remarks data structure:
"remarks" :
[
{
"description" :
[
"She sells sea shells down by the sea shore.",
"Originally written by Terry Sullivan."
]
}
]
Figure 5
Ma, et al. Expires June 21, 2024 [Page 7]
Internet-Draft Identifier Data Response Protocol December 21, 2023
Note that objects in the "remarks" array may also have a "links" array.
While the "title" and "description" fields are intended primarily for
human consumption, the "type" string contains a well-known value to be
registered with TLN for programmatic use.
An example of the remarks data structure:
"remarks" :
[
{
"type" : "information truncated due to authorization",
"description" :
[
"Some identifier data may not have been given.",
"Use proper authorization credentials to see all of it."
]
}
]
Figure 6
4.4. Language Identifier
This data structure consists solely of a name/value pair, where the
name is "lang" and the value is a string containing a language
identifier as described in [RFC5646].
"lang" : "mn-Cyrl-MN"
5. Nodes
An identifier appears throughout this document and is an appropriate
response for the /identifier/XXXX query defined in "Industrial
Internet Identifier Data Access Protocol (IIIDAP) Query Format"
[IDENTIFIER-QUERY]. It represents the information of a SLN or ELN.
All of these representations are expected to represent in JSON
[RFC8259].
The following is an example of an entity.
{
"iiidapConformance" :
[
"iiidap_level_0"
],
"notices" :

6. Error Response Body
Some non-answer responses may return entity bodies with information
that could be more descriptive.
The basic structure of that response is an object containing an
error code number (corresponding to the HTTP response code) followed
by a string named "title" and an array of strings named
"description".
This is an example of the common response body.
{
"errorCode": 418,
"title": "Your Beverage Choice is Not Available",
"description":
[
"I know coffee has more ummppphhh.",
"Sorry, dude!"
]
}
Figure 8
This is an example of the common response body with an
iiidapConformance and notices data structures:
{
"iiidapConformance" :
[
"iiidap_level_0"
],
"notices" :
[

"lang" : "en",
"errorCode": 418,
"title": "Your beverage choice is not available",
"description":
[
"I know coffee has more ummppphhh.",
"Sorry, dude!"
]
}
Figure 9
7. Responding to Help Queries
The appropriate response to /help queries as defined by [IDENTIFIER-
QUERY] is to use the notices structure as defined in Section 4.3.
This is an example of a response to a /help query including the
iiidapConformance data structure.
{
"iiidapConformance" :
[
"iiidap_level_0"
],
"notices" :
[
{
"title" : "Authentication Policy",
"description" :

"rel" : "alternate",
"type" : "text/html",
"href" : "http://www.example.com/auth_policy.html"
}
]
}
]
}
Figure 10
8. Responding To Searches
[IDENTIFIER-QUERY] specifies the pattern of searches through the
names of SLN and ELN. Responses to searches take the form of an
array of identifier objects. These arrays are contained within the
response object.
The following is an elided example of a response to a /names search.
{
"iiidapConformance" :
[
"iiidap_level_0"
],
...
"NodeSearchResults" :
[
{
"identifier" : "86.100.1",
"regTime" : "2019-12-12T08:57:32.0Z",
"status" : "ok",
...
},
{
"identifier" : "86.100.2",
"regTime" : "2018-12-12T08:57:32.0Z",
"status" : "ok",
...

]
}
Figure 11
9. Indicating Truncated Responses
In cases where the data of a response needs to be limited or parts
of the data need to be omitted, the response is considered
"truncated". A truncated response is still valid JSON, but some of
the results in a search set or some of the data in an object are not
provided by the server. A server may indicate this by including a
typed notice in the response object.
{
"iiidapConformance" :
[
"iiidap_level_0"
],
"notices" :
[
{
"title" : "Search Policy",
"type" : "result set truncated due to authorization",
"description" :
[
"Search results are limited to 25 per day per querying IP."
],
"links" :
[
{
"value" : "http://example.net/help",
"rel" : "alternate",
"type" : "text/html",
"href" : "http://www.example.com/search_policy.html"
}
]
}
],
"domainSearchResults" :
[
...
]
}
Figure 12

Internet-Draft Identifier Data Response Protocol December 21, 2023
A similar technique can be used with a typed remark where a single
object has been returned and data in that object has been truncated.
The following is an elided example of a truncated data.
{
"identifier" : "86.100.1",
"regTime" : "2019-12-12T08:57:32.0Z",
"status" : "ok",

11. Security Considerations
This specification model information serialized in JSON format. As
JSON is a subset of JavaScript, implementations are advised to

Internet-Draft Identifier Data Response Protocol December 21, 2023
follow the security considerations outlined in Section 6 of
[RFC8259] to prevent code injection.
Though not specific to JSON, IIIDAP implementers should be aware of
the security considerations specified in [IDENTIFIER-HTTP] and the
security requirements and considerations in [IDENTIFIER-SECURITY].
Finally, service operators should be aware of the privacy mechanisms
noted in Section 13.
12. Internationalization Considerations
12.1. Character Encoding
The default text encoding for JSON responses in IIIDAP is UTF-8
[RFC3629], and all servers and clients MUST support UTF-8.
12.2. URIs and IRIs
[IDENTIFIER-HTTP] defines the use of URIs and IRIs in IIIDAP.
13. Privacy Considerations
This specification suggests some of values to identifier information
that has been marked as private and/or has been removed or obscured,
except:
o identifer
o name of a node
o type of a node
o introduce of a node
A few of the status values indicate that there are privacy concerns
associated with the identifier object. The following status codes
SHOULD be used to describe data elements of a response when
appropriate:
o private -- The object is not be shared in query responses, unless
the user is authorized to view this information.
o removed -- Data elements within the object have been collected
but have been omitted from the response. This option can be used
to prevent unauthorized access to associated identifier objects
without the need to mark them as private.

Internet-Draft Identifier Data Response Protocol December 21, 2023
o obscured -- Data elements within the object have been collected,
but the response value has been altered so that values are not
easily discernible. A value changed from "1212" to "XXXX" is an
example of obscured data. This option may reveal privacy
sensitive information and should only be used when data
sensitivity does not require a more protective option like
"private" or "removed".
