Extracted elements (6)
RFC 5031 restricted 'sos' sub-service URN registration to emergency services 'offered widely and in different countries,' which blocked registration of country-specific services such as South Korea's 'Reporting spies' and Colombia's 'GAULA (anti-kidnapping)' emergency services. This document relaxes that constraint to allow registration when a service is offered in at least one country at the time of registration.
RFC 7163 replaces only the 2nd paragraph of Section 4.2 of RFC 5031 and does not alter any other part of that specification. Implementations and registrations made under the old 'widely and in different countries' criterion remain valid.
Additional 'sos' 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 for 'sos' sub-service URN registrations should only approve services that are used for emergency purposes, are offered in at least one country, do not duplicate an existing 'sos' service URN, and whose service description and URN are defined as broadly as possible to encourage reuse.
IANA updated the reference for the "'sos' Sub-Services" registry at iana.org/assignments/urn-serviceid-labels to point to RFC 7163 instead of RFC 5031, reflecting the new expert review guidance.
This document does not update the Security Considerations of RFC 5031; all security properties of the 'sos' URN registration process remain as specified there.
