Introduction   The advice to experts for registering sub-services of the service URN   with the 'sos' service type is provided inSection 4.2 of RFC 5031   [RFC5031] as follows:      The 'sos' service type describes emergency services requiring an      immediate response, typically offered by various branches of the      government or other public institutions.  Additional sub-services      can be added after expert review and must be of general public      interest and have a similar emergency nature.  The expert is      designated by the ECRIT working group, its successor, or, in their      absence, the IESG.  The expert review should only approve      emergency services that are offered widely and in different      countries, with approximately the same caller expectation in terms      of services rendered.  The 'sos' service is not meant to invoke      general government, public information, counseling, or social      services.   Some existing emergency services are, at least initially, offered in   only one country.  Examples are the "Reporting spies" emergency   service offered in South Korea and the "GAULA (anti-kidnapping)"   emergency service offered in Colombia according to [WIKIPEDIA].   Future emergency service might also initially be introduced in only   one country.   The advice to experts of sub-services of the service URN with the   'sos' service type provided inRFC 5031 [RFC5031] prevents the   registration of a sub-service of the service URN with the 'sos'   service type for a service that, at the time of registration, is   offered in one country only.Holmberg & Sedlacek          Standards Track                    [Page 2]

RFC 7163           Country-Specific Emergency Services        March 2014   This document updates the 2nd paragraph ofSection 4.2 of RFC 5031   [RFC5031], in order to allow the registration of service URNs with   the 'sos' service type for emergency services that, at the time of   registration, are offered in one country only.2.  Conventions   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this   document are to be interpreted as described inBCP 14,RFC 2119   [RFC2119].3.  Update toRFC 50313.1.  GeneralSection 3.2 of this document replaces the text of the 2nd paragraph   ofSection 4.2 (Sub-Services for the 'sos' Service) ofRFC 5031   [RFC5031].3.2.  New Text Replacing the Text of the 2nd Paragraph ofSection 4.2 ofRFC 5031   The 'sos' service type describes emergency services requiring an   immediate response, typically offered by various branches of the   government or other public institutions.  Additional sub-services can   be added after expert review.  The expert is designated by the ECRIT   working group, its successor, or, in their absence, the IESG.  The   designated expert should only approve services that are to be used   for emergency purposes, that are offered in at least one country,   that do not match the description of any existing service URN with   the 'sos' service type, and where the service description and the URN   are defined as broadly as possible to encourage reuse.  The 'sos'   service is not meant to invoke general government, public   information, counseling, or social services.4.  IANA Considerations   This document updates the advice to the expert of the "'sos' Sub-   Services" registry.  IANA has updated the reference for that registry   <http://www.iana.org/assignments/urn-serviceid-labels> to point to   this document (instead ofRFC 5031 [RFC5031]).5.  Security Considerations   This document does not update the Security Considerations ofRFC5031.Holmberg & Sedlacek          Standards Track                    [Page 3]
