Abstract Advertising Digital Identification (Ad-ID) Identifiers are used identifying Advertising Assets across all media platforms (over the air, on-line, over the top, mobile, place based). This document defines the formal Uniform Resource Name (URN) Namespace Identifier (NID) for Ad-ID Identifiers. Table of Contents 1. Introduction...................................................2 2.

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. Ad-ID's data model includes the registration of advertising assets using standardized descriptive metadata about ads including advertiser, product, commercial title and other essential data. Ad-ID Identifiers are unique codes for each advertising asset digitally, and applies that code to all media. [Ad-ID-INTRO] provides additional background information. 2. Completed URN Namespace Definition Template The namespace definition according to the template in [RFC3406] is as follows: Wold Expires October 12, 2016 [Page 2] Internet-Draft Ad-ID URN Namespace Definition April 2016 Namespace ID: adid Registration Information: Version 1 2016-03-22 Declared registrant of the namespace: Name: Advertising Digital Identification, LLC Address: 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 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. Wold Expires October 12, 2016 [Page 3] Internet-Draft Ad-ID URN Namespace Definition April 2016 Video Format: H - High Definition D - Three-Dimensional The URN representation URN-ADID of an Ad-ID Identifier conforms to the syntax specified below using ABNF (as specified in IETF RFC 5234): URN-ADID = "urn:adid:" full_adid_identifier full_adid_identifier = adid_prefix adid_code [adid_suffix] adid_prefix = (ALPHA / %x31-39) 3*alphanum ; first character not zero adid_code = 7*alphanum adid_suffix = "H" / "D" alphanum = ALPHA / DIGIT Examples: Standard Definition (SD): urn:adid:ABCD0001000 High Definition (HD): urn:adid:ABCD0001000H Three-dimensional (3D): urn:adid:ABCD00010003 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. Wold Expires October 12, 2016 [Page 4] Internet-Draft Ad-ID URN Namespace Definition April 2016 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. 4. 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 when using an Ad-ID Identifier as a criterion for accessing restricted resources can result in granting unauthorized access. 5. 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. 6. References 6.1.

Informative References [Ad-ID-INTRO] Ad-ID Identifiers are 11 characters except for High Definition (HD) or Three-Dimensional (3D) codes, which have an H or D in the 12th character. Wold Expires October 12, 2016 [Page 6] Internet-Draft Ad-ID URN Namespace Definition April 2016 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.
