+
+1.  Introduction
+
+   This document defines the formal Uniform Resource Name (URN)
+   Namespace Identifier (NID) for Ad-IDs.
+
+   Ad-ID is the industry standard for identifying advertising assets
+   across all media platforms (e.g., over the air, online, over the top,
+   mobile, and place based).  Ad-IDs are unique codes for each creative
+   advertising asset.  Those unique codes are applied to all media.
+
+   Ad-IDs are an eleven-character ASCII string except for High
+   Definition (HD) or Three-Dimensional (3D) codes, which have an H or D
+   as 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 using the unique code.
+
+   See Appendix A for additional background information.
+
+2.  URN Namespace Definition Template
+
+   Using the template in [RFC3406], the namespace definition is as
+   follows:
+
+   Namespace ID:
+
+      adid
+

+
+      Registering organization:
+         Advertising Digital Identification, LLC

+
+   Declaration of syntactic structure:
+
+      The identifier structure is an Ad-ID that 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
+
+      The URN representation URN-ADID of an Ad-ID conforms to the
+      following syntax (expressed using ABNF [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.

+RFC 8107             Ad-ID URN Namespace Definition           March 2017
+
+
+   Identifier uniqueness considerations:
+
+      The Registrar (Advertising Digital Identification, LLC) is
+      responsible for managing the assignment of the Ad-ID and shall
+      ensure its uniqueness by checking the identifier against the list
+      of existing identifiers.  In addition, each Ad-ID is associated
+      with a its own unique URN-ADID.
+
+      Ad-ID Registrar has assigned "adid" as a unique identifier.  It is
+      associated with a single URN-ADID.
+
+   Identifier persistence considerations:
+
+      The assignment process guarantees that 'adids' will not be
+      reassigned or reused, and the binding between the identifier and
+      its resource is permanent.
+
+      These rules apply to this URN namespace.
+
+   Process of identifier assignment:
+
+      Ad-IDs are generated by the Ad-ID's proprietary registration
+      procedures.
+
+   Process for identifier resolution:
+
+      Ad-ID URNs are resolved via URN resolvers that are maintained by
+      the Ad-ID.
+
+   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 a 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

+
+RFC 8107             Ad-ID URN Namespace Definition           March 2017
+
+
+   Scope:
+
+      Ad-IDs are centrally registered, globally unique identifiers of
+      advertising assets that are used worldwide.
+
+3.  Namespace Considerations
+
+   Ad-IDs are intended for use in Internet applications, where URNs are
+   routinely used to identify audiovisual resources.  There is no direct
+   mapping from Ad-IDs to existing URN namespaces.
+
+4.  Community Considerations
+
+   The primary registrants of Ad-IDs are advertisers and agencies.  Ad-
+   IDs can be used by anyone to unambiguously identify advertising
+   assets and retrieve underlying metadata.  The primary benefits of its
+   use are providing greater transparency and accountability in the
+   advertising marketplace, helping to eliminate costly errors
+   associated with the inconsistent use of advertising-asset identifiers
+   throughout the advertising supply chain, and enabling a 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.  However, note that failure to
+   conform to the syntactic and lexical equivalence rules specified in
+   [RFC3406] when using an Ad-ID as a criterion for accessing restricted
+   resources can result in granting unauthorized access.
+
+6.  IANA Considerations
+
+   This document defines "ad-id" in the "Formal URN Namespaces"
+   registry.

+Appendix A.  Additional Background Information
+
+   Ad-IDs are an eleven-character ASCII string except for High
+   Definition (HD) or Three-Dimensional (3D) codes, which have an H or D
+   as the 12th character.
+
+   Ad-ID may have Complimentary Definition Codes (CDCs), 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
