Abstract

  This document updates the registration guidance provided in Section
  4.2 of RFC 5031, which allows the registration of service URNs with
  the 'sos' service type only for emergency services "that are offered
  widely and in different countries".  This document updates those
  instructions to allow such registrations when, at the time of
  registration, those services are offered in only one country.

1.  Introduction

  The advice to experts for registering sub-services of the service URN
  with the 'sos' service type is provided in Section 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 in RFC 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.

RFC 7163           Country-Specific Emergency Services        March 2014


  This document updates the 2nd paragraph of Section 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 in BCP 14, RFC 2119
  [RFC2119].

3.  Update to RFC 5031

3.1.  General

  Section 3.2 of this document replaces the text of the 2nd paragraph
  of Section 4.2 (Sub-Services for the 'sos' Service) of RFC 5031
  [RFC5031].

3.2.  New Text Replacing the Text of the 2nd Paragraph of Section 4.2 of
     RFC 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 of RFC 5031 [RFC5031]).

5.  Security Considerations

  This document does not update the Security Considerations of RFC
  5031.
