URN for Country-Specific Emergency Services
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.
