Excerpt from RFC 5031 section 4.2.

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 one country only. Examples are the "Reporting spies" emergency service offered in South Korea and the "GAULA (anti-kidnapping)" emergency service offered in Colombia according to http://en.wikipedia.org/wiki/Emergency_telephone_number. Future emergency service might also initially be introduced in one country only.

The policy for registration of sub-services of the service URN with the 'sos' service type, as defined 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.

This document updates section 4.2 of RFC 5031, 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. Problem statement

The policy for registration of sub-services of the service URN with the 'sos' service type, as defined in RFC 5031 [RFC5031], prevents the registration of a sub-service of the service URN with the 'sos' service type for an emergency service that, at the time of registration, is offered in one country only.

4. Requirement

REQ-1: It MUST be possible to register with IANA a sub-service of the service URN with the 'sos' service type as, defined in RFC 5031 [RFC5031], for an emergency service offered in one country only.

5. Update to RFC 5031

5.1. General

This section document updates replaces the text of the section 4.2 (Sub-Services for the 'sos' Service) of RFC 5031 with the text of section 6.3 of this document.

5.2. Original text of section 4.2 of RFC 5031

This section defines the first service registration within the IANA registry defined in Section 4.1, using the top-level service label 'sos'.

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.

urn:service:sos  The generic 'sos' service reaches a public safety
   answering point (PSAP), which in turn dispatches aid appropriate
   to the emergency.  It encompasses all of the services listed
   below.

urn:service:sos.ambulance  This service identifier reaches an
   ambulance service that provides emergency medical assistance and
   transportation.

urn:service:sos.animal-control  Animal control typically enforces
   laws and ordinances pertaining to animal control and management,
   investigates cases of animal abuse, educates the community in
   responsible pet ownership and wildlife care, and provides for the
   housing and care of homeless animals, among other animal-related
   services.

urn:service:sos.fire  The 'fire' service identifier summons the fire
   service, also known as the fire brigade or fire department.

urn:service:sos.gas  The 'gas' service allows the reporting of
   natural gas (and other flammable gas) leaks or other natural gas
   emergencies.

urn:service:sos.marine  The 'marine' service refers to maritime
   search and rescue services such as those offered by the coast
   guard, lifeboat, or surf lifesavers.

urn:service:sos.mountain  The 'mountain' service refers to mountain
   rescue services (i.e., search and rescue activities that occur in
   a mountainous environment), although the term is sometimes also
   used to apply to search and rescue in other wilderness
   environments.

urn:service:sos.physician  The 'physician' emergency service connects
   the caller to a physician referral service.

urn:service:sos.poison  The 'poison' service refers to special
   information centers set up to inform citizens about how to respond
   to potential poisoning.  These poison control centers maintain a
   database of poisons and appropriate emergency treatment.

urn:service:sos.police  The 'police' service refers to the police
   department or other law enforcement authorities.

5.3. New text replacing section 4.2 of RFC 5031

This section defines the first service registration within the IANA registry defined in Section 4.1, using the top-level service label 'sos'.

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 expert review should only approve services that have emergency nature, that are offered in at least one country, that do not match 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.

urn:service:sos  The generic 'sos' service reaches a public safety
   answering point (PSAP), which in turn dispatches aid appropriate
   to the emergency.  It encompasses all of the services listed
   below.

urn:service:sos.ambulance  This service identifier reaches an
   ambulance service that provides emergency medical assistance and
   transportation.

urn:service:sos.animal-control  Animal control typically enforces
   laws and ordinances pertaining to animal control and management,
   investigates cases of animal abuse, educates the community in
   responsible pet ownership and wildlife care, and provides for the
   housing and care of homeless animals, among other animal-related
   services.

urn:service:sos.fire  The 'fire' service identifier summons the fire
   service, also known as the fire brigade or fire department.

urn:service:sos.gas  The 'gas' service allows the reporting of
   natural gas (and other flammable gas) leaks or other natural gas
   emergencies.

urn:service:sos.marine  The 'marine' service refers to maritime
   search and rescue services such as those offered by the coast
   guard, lifeboat, or surf lifesavers.

urn:service:sos.mountain  The 'mountain' service refers to mountain
   rescue services (i.e., search and rescue activities that occur in
   a mountainous environment), although the term is sometimes also
   used to apply to search and rescue in other wilderness
   environments.

urn:service:sos.physician  The 'physician' emergency service connects
   the caller to a physician referral service.

urn:service:sos.poison  The 'poison' service refers to special
   information centers set up to inform citizens about how to respond
   to potential poisoning.  These poison control centers maintain a
   database of poisons and appropriate emergency treatment.

urn:service:sos.police  The 'police' service refers to the police
   department or other law enforcement authorities.

6. IANA Considerations

OPEN ISSUE: Do we need to request IANA to take the updated section into consideration, or is IANA expected to do that by default, as the document updates the RFC 5031 procedures?

7. Change Log

[RFC EDITOR NOTE: Please remove this section when publishing]

Changes from draft-holmberg-ecrit-country-emg-urn-01

• Technical fix: Instead of creating a new sub-tree, the 'sos' registration rules in RFC 5031 are updated, to allow registration of URNs that, at the time of registration, are specific to a single country.

Changes from draft-holmberg-ecrit-country-emg-urn-00

• Editorial fix: cannot be not fulfilled -> cannot be fulfilled

8. Security Considerations

TBD
