Introduction 62 This document defines the formal Uniform Resource Name (URN) 63 Namespace Identifier (NID) for Ad-ID Identifiers. 65 Ad-ID is the industry standard for identifying advertising assets 66 across all media platforms. Ad-ID's data model includes the 67 registration of advertising assets using standardized descriptive 68 metadata about ads including advertiser, product, commercial title 69 and other essential data. Ad-ID Identifiers are unique codes for 70 each advertising asset digitally, and applies that code to all 71 media. 73 [Ad-ID-INTRO] provides additional background information. 74 2. URN Namespace Definition Template 76 The namespace definition according to the template in [RFC3406] is 77 as follows: 79 Namespace ID: 81 adid 83 Registration Information: 85 Version 1 86 2016-03-22 88 Declared registrant of the namespace: 90 Name: 92 Advertising Digital Identification, LLC 94 Address: 96 Advertising Digital Identification, LLC 97 11020 David Taylor Drive, Suite 305 98 Charlotte, NC 28262-1103 99 USA 101 Contact: 103 URL: http://www.ad-id.org/contact 104 Email: cs@ad-id.org 106 Declaration of syntactic structure: 108 The identifier structure is as follows: 110 An Ad-ID Identifier consists of a unique eleven character string 111 or a unique twelve character string (video codes only). 113 This string is divided into three parts: 115 1. A four-character alphanumeric Company Prefix, not starting 116 with "0" 117 2. A seven-character alphanumeric code 118 3. An optional one-character Video Format Identifier. 119 H - High Definition 120 D - Three-Dimensional 122 The URN representation URN-ADID of an Ad-ID Identifier 123 conforms to the syntax (expressed using ABNF (as specified in 124 [RFC5234]) : 125 URN-ADID = "urn:adid:" full-adid-identifier 126 full-adid-identifier = 127 full-adid-prefix full-adid-code [full-adid-suffix] 128 full-adid-prefix = (alpha / %x31-39) 3*alphanum 129 full-adid-code = 7*alphanum 130 full-adid-suffix = "H" / "D" 131 alphanum = alpha / digit 133 Examples: 135 Standard Definition: urn:adid:ABCD0001000 136 High Definition: urn:adid:ABCD0001000H 138 Relevant ancillary documentation: 140 [SMPTERP2092-1] specifies Advertising Digital Identifier (Ad-ID) 141 Representations. 143 Identifier uniqueness considerations: 145 The Registrar (Advertising Digital Identification, LLC) is 146 responsible for managing the assignment of the Ad-ID Identifier 147 and shall ensure the uniqueness by checking the identifier against 148 the list of existing ids. 150 Ad-ID assigns the identifier, adid, in such a way that the 151 uniqueness of the 'adid' will be maintained. Furthermore, an Ad- 152 ID Identifier is associated with a single URN-ADID. 154 Identifier persistence considerations: 156 The assignment process guarantees that 'adids' are not reassigned 157 or reused and the binding between the id and its resource is 158 permanent. 160 By reference this URN namespace inherits those rules 162 Process of identifier assignment: 164 Ad-IDs are generated by Ad-ID's proprietary registration 165 procedures. 167 Process for identifier resolution: 169 Ad-ID URNs are resolved via URN resolvers run under Ad-ID's 170 responsibility. 172 Rules for Lexical Equivalence: 174 Lexical equivalence of URN-ADID is defined by case-insensitive 175 string match. 177 Conformance with URN Syntax: 179 As specified above, the syntax of URN-ADID is a subset of the URN 180 syntax specified in [RFC2141]. 182 Validation mechanism: 184 The validity of an URN-ADID can be checked using Ad-ID's web 185 services. For more information on Ad-ID's web services, please 186 refer to the following links: 187 http://www.ad-id.org/user-support/faqs/faq-category/web-services 188 http://www.ad-id.org/ad-id-web-services-api-guide 190 Scope: 192 Ad-ID Identifiers are centrally registered, globally unique 193 identifiers of advertising assets, used worldwide. 195 3. Namespace Considerations 197 Ad-ID Identifiers are intended for use in Internet applications, 198 where URNs are routinely used to identify audiovisual resources. 199 There is no direct mapping from Ad-ID Identifiers to existing URN 200 namespaces 202 4. Community Considerations 204 The primary registrants of Ad-ID Identifiers are advertisers and 205 agencies. Ad-ID Identifiers can be used by anyone to unambiguously 206 identify advertising assets and retrieve underlying metadata. The 207 primary benefits of its use are greater transparency and 208 accountability in the advertising marketplace, help eliminate costly 209 errors associated with the inconsistent use of advertising asset 210 identifiers throughout the advertising supply chain, and enable more 211 granular audience measurement across multiple platforms. 213 5. Security Considerations 215 This document specifies the syntax of the Ad-ID-URN namespace and 216 makes no security representations. Note however that failure to 217 conform to the syntactic and lexical equivalence rules specified 218 when using an Ad-ID Identifier as a criterion for accessing 219 restricted resources can result in granting unauthorized access. 221 6. IANA Considerations 223 This document defines a URN NID registration that is to be entered 224 into the IANA registry of URN NIDs. It specifically requests the 225 Ad-ID NID. 227 7.
