1. Introduction
This document defines the formal Uniform Resource Name (URN)
Namespace Identifier (NID) for Ad-ID Identifiers.
Ad-ID is the industry standard for identifying advertising assets
across all media platforms (over the air, on-line, over the top,
mobile, place based). Ad-ID Identifiers are unique codes for each
creative advertising asset. Those unique codes are applied to all
media.
Ad-ID Identifiers are an eleven character ASCII string except for
High Definition (HD) or Three-Dimensional (3D) codes, which have an
H or D in the 12th character.
Ad-ID also provides descriptive metadata about the advertisement.
The metadata includes the advertiser, brand, product, commercial
title, product categorization, and other essential data about the
advertisement. The metadata can be retrieved by using the unique
code.
[Ad-ID-INTRO] provides additional background information.
2. URN Namespace Definition Template
The namespace definition according to the template in [RFC3406] is
as follows:
Namespace ID:

Declaration of syntactic structure:
The identifier structure is as follows:
An Ad-ID Identifier consists of a unique eleven character string
or a unique twelve character string (video codes only).
This string is divided into three parts:
1. A four-character alphanumeric Company Prefix, not starting
with "0"
2. A seven-character alphanumeric code
3. An optional one-character Video Format Identifier.
H - High Definition
D - Three-Dimensional

Internet-Draft Ad-ID URN Namespace Definition November 16, 2016
The URN representation URN-ADID of an Ad-ID Identifier
conforms to the syntax (expressed using ABNF (as specified in
[RFC5234]) :
URN-ADID = "urn:adid:" full-adid-identifier
full-adid-identifier =
full-adid-prefix full-adid-code [full-adid-suffix]
full-adid-prefix = (ALPHA / %x31-39) 3*alphanum
full-adid-code = 7*alphanum
full-adid-suffix = "H" / "D"
alphanum = ALPHA / DIGIT
Examples:
Standard Definition: urn:adid:ABCD0001000
High Definition: urn:adid:ABCD0001000H
Relevant ancillary documentation:
[SMPTERP2092-1] specifies Advertising Digital Identifier (Ad-ID)
Representations.
Identifier uniqueness considerations:
The Registrar (Advertising Digital Identification, LLC) is
responsible for managing the assignment of the Ad-ID Identifier
and shall ensure the uniqueness by checking the identifier against
the list of existing ids.
Ad-ID assigns the identifier, adid, in such a way that the
uniqueness of the 'adid' will be maintained. Furthermore, an Ad-
ID Identifier is associated with a single URN-ADID.
Identifier persistence considerations:
The assignment process guarantees that 'adids' are not reassigned
or reused and the binding between the id and its resource is
permanent.
By reference this URN namespace inherits those rules
Process of identifier assignment:

Internet-Draft Ad-ID URN Namespace Definition November 16, 2016
Ad-IDs are generated by Ad-ID's proprietary registration
procedures.
Process for identifier resolution:
Ad-ID URNs are resolved via URN resolvers run under Ad-ID's
responsibility.
Rules for Lexical Equivalence:
Lexical equivalence of URN-ADID is defined by case-insensitive
string match.
Conformance with URN Syntax:
As specified above, the syntax of URN-ADID is a subset of the URN
syntax specified in [RFC2141].
Validation mechanism:
The validity of an URN-ADID can be checked using Ad-ID's web
services. For more information on Ad-ID's web services, please
refer to the following links:
http://www.ad-id.org/user-support/faqs/faq-category/web-services
http://www.ad-id.org/ad-id-web-services-api-guide
Scope:
Ad-ID Identifiers are centrally registered, globally unique
identifiers of advertising assets, used worldwide.
3. Namespace Considerations
Ad-ID Identifiers are intended for use in Internet applications,
where URNs are routinely used to identify audiovisual resources.
There is no direct mapping from Ad-ID Identifiers to existing URN
namespaces

4. Community Considerations
The primary registrants of Ad-ID Identifiers are advertisers and
agencies. Ad-ID Identifiers can be used by anyone to unambiguously
identify advertising assets and retrieve underlying metadata. The
primary benefits of its use are greater transparency and
accountability in the advertising marketplace, help eliminate costly
errors associated with the inconsistent use of advertising asset
identifiers throughout the advertising supply chain, and enable more
granular audience measurement across multiple platforms.
5. Security Considerations
This document specifies the syntax of the Ad-ID-URN namespace and
makes no security representations. Note however that failure to
conform to the syntactic and lexical equivalence rules specified in
[RFC3406] when using an Ad-ID Identifier as a criterion for
accessing restricted resources can result in granting unauthorized
access.
6. IANA Considerations
This document defines a URN NID registration that is to be entered
into the IANA registry of URN NIDs. It specifically requests the
Ad-ID NID.

[Ad-ID-INTRO]
Ad-ID Identifiers are an eleven character ASCII string except for
High Definition (HD) or Three-Dimensional (3D) codes, which have an
H or D in the 12th character.
Ad-ID may have Complimentary Definition Codes (CDC's), which are
matching SD, HD and/or 3D codes where only the 12th character of the
code varies. This only applies to Video codes.
For example, a video with a standard format and high definition
format would have a single code for each format.
Standard: ABCD1234000
High Definition: ABCD1234000H
