RFC 8107

Advertising Digital Identifier (Ad-ID) URN Namespace Definition

📅 published March 2017, from ietf

📚 Advertising Digital Identifier (Ad-ID) URN Namespace Definition 🎀

Okay bestie, this one is a whole vibe 💖 It's RFC 8107, written by J. Wold and published in March 2017 as an Informational document 🦋 It's about the URN namespace "adid" for Ad-IDs, which are the codes that identify advertising assets. Ad-IDs are the industry standard across all media platforms 📺 It's not on the Standards Track, so it's just here to inform, not to set rules for the Internet 🌸 Nothing in the title block says it obsoletes or updates any other RFC, so it's a clean slate ✨

Here's the status of this memo, plus the copyright stuff, because yes, we read the boring parts too 🙈

1. Introduction ✨

1. Introduction

Okay so 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, like over the air, online, over the top, mobile, and place based 📺 Ad-IDs are unique codes for each creative advertising asset, and those codes get 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 gives you descriptive metadata about the ad 💖 That includes the advertiser, brand, product, commercial title, product categorization, and other essential data. You can retrieve the metadata using the unique code 🧚

See Appendix A for more background info 🌈

2. URN Namespace Definition Template 💜

Using the template in [RFC3406], the namespace definition goes like this 🍓

Namespace ID:

adid

Registration Information:

Version 1, 2016-03-22

Declared registrant of the namespace:

Registering organization: Advertising Digital Identification, LLC, 11020 David Taylor Drive, Suite 305, Charlotte, NC 28262-1103, USA

Contact: URL http://www.ad-id.org/contact, Email cs@ad-id.org 📮

Declaration of syntactic structure:

The identifier structure is an Ad-ID made of a unique eleven-character string or a unique twelve-character string (video codes only) 🎬

This string is split 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 follows this syntax (written in 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:

Identifier uniqueness considerations:

The Registrar (Advertising Digital Identification, LLC) is responsible for managing the assignment of the Ad-ID and MUST 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 info on those, check these 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-IDs are centrally registered, globally unique identifiers of advertising assets that are used worldwide 🌍

3. Namespace Considerations 🌈

Ad-IDs are meant for 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 the underlying metadata. The main benefits are greater transparency and accountability in the advertising marketplace, fewer costly errors from inconsistent use of advertising-asset identifiers across the supply chain, and more granular audience measurement across multiple platforms 📊✨

5. Security Considerations 🔐

⚠️ This is the serious part, so pay attention 💀

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 a high-definition format would have a single code for each format:

Standard: ABCD1234000
High Definition: ABCD1234000H
