Introduction 62 Nowadays location-based services are widespread. Devices can detect 63 a user location and retrieve all available services in the 64 sourroundings of that location. A particular service can be 65 described by one or multiple terms such as "restaurant", "parking" 66 and "ATM machine". All such terms, however, need to be formally 67 defined so that a registry can be built and used to assure 68 consistency and compatibility between devices and between service 69 providers. Since descriptive terms for services are almost 70 unbounded, such registry would contain the most common terms. In 71 this document we update the policy for defining new terms, that is 72 new service-identifying labels. 74 2. Requirements notation 76 The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 77 "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this 78 document are to be interpreted as described in [RFC2119]. 80 3. Namespace Guidelines 82 [NOTE: Have we agreed on this approach? Do we allow private 83 namespaces?] 85 Whereas one entity applies for the registraton of several new top- 86 level services which are of no interest to the general public, the 87 expert reviewer SHOULD consider the creation of an ad-hoc private 88 namespace (e.g., urn:nena [citation needed]) under which such entity 89 would be free to define its own set of services and service labels. 91 On the other hand, if the new top-level services are of interest to 92 the general public or there is just one single top-level service to 93 be registered, the expert reviewer SHOULD decide for registration in 94 the public namespace domain (i.e., urn:service). 96 Namespaces MAY at their discretion use discovery mechanisms other 97 than the one described in [RFC5222]. 99 4. Guidelines for the creation of new top-level services 101 The number of services that can be defined is very large. New 102 services, however, SHOULD at least satisfy the following guidelines. 104 - The service MUST NOT overlap with any other service previously 105 registered; 107 - The service has to be of general interest; 109 - It should not be specific to a particular country or region; 111 - The language in which the new service is defined MUST be English 112 (this is a protocol token, not meant to be shown to humans); 114 - The newly defined services SHOULD correspond to a standard 115 statistical classification of enterprises or services, such as the 116 North American Industry Classification System (NAICS). 118 5. IANA Considerations 120 This document updates Section 4.1 of [RFC5031] in that the policy for 121 adding top-level service labels is "Expert Review". The expert is 122 designated by the RAI Area Director. [NOTE: Add requirement for 123 external non-IETF document or template here?] 125 6. Security Considerations 127 This document does not raise security issues. 129 7.
