The MODERN working group will define a set of Internet-based mechanisms for the
purposes of managing the acquisition and resolution of telephone numbers (TNs)
in an IP environment. Devices, applications, and network tools increasingly
need to request and acquire TN delegations from authorities. The output of the
working group should make distribution, acquisition, and management of TNs
simpler for all entities involved.

The working group will define an information management framework for the roles
and functions involved in associating information with one or more TNs in an IP
environment.  The working group will also identify protocol mechanisms to
support the interactions between the functions defined by the framework. This
includes either recommending or defining protocol mechanisms for acquiring,
associating and resolving TNs, with a preference for use of existing protocol
mechanisms. TNs may either be managed in a hierarchical tree, or in a
distributed registry. The protocol mechanism for acquiring TNs will provide an
enrollment process for the entities that use and manage TNs.

The protocol mechanism for resolving TNs will allow entities such as service
providers, devices, and applications to access data related to TNs. Maintaining
reliability, real-time application performance, and security and privacy for
both the data and the protocol interactions are primary considerations. The
working group will take into consideration existing IETF work including STIR,
ENUM, SPEERMINT, DRINKS and SCIM as well as work in other relevant standards

The work of this group will focus on TNs, as defined in RFC3966, and blocks of
TNs, that are used to initiate communication with another user of a service.
The group acknowledges ITU Plenipotentiary Conference Resolution 133 which
recognizes the existing role and sovereignty of ITU Member States with respect
to allocation and management of their country code numbering resources as
enshrined in Recommendation ITU-T E.164, and is cognizant of other related
ITU-T Recommendations, including E.164.1 and E.190. There is an expectation
that aspects of the architecture and protocols defined by the working group
will be reusable for other user-focused identifiers. Any such extensions or
reuse of MODERN mechanisms are out of scope for the MODERN working group.
Solutions and mechanisms created by the working group will be flexible enough
to accommodate different policies for TN assignment and management, for example
those established by different regulatory agencies.
