I believe that this Charter is poorly suited to developing solutions to the problem faced by disabled users of realtime emergency services.
In the case of access to emergency services by the disabled, the goal is not "selection of the best-fit language", but rather, routing of the call and media so as to pull together the services best fitting the emergency situation and the disabilities of the caller, as well as the capabilities of the device and intermediaries which may sit between the caller and the PSAP. Not only are media and language intrinsically linked, but also, the ways in which calls are routed is influenced and in some cases prescribed by regulation and national standards. Simply put, draft-gellens-slim-negotiating-human-language lacks appropriate consideration of the problem context. Specifying it as the starting point is therefore inappropriate. As an example, today the call flow described in Section 4.5 would most likely result in rejection of the video portion of the call by the PSAP, leaving the dispatcher with no means of communicating with the hearing-impaired caller, thus leaving the caller worse off than they are today attempting to make an emergency call within the (cumbersome and error/delay-prone) Video Relay Service. A fuller consideration of the problem context would involve consideration of current operation of relay services and proposals for their evolution. Attempting to develop this problem context within a WG that is also attempting to deal with language-selection in email would be frustrating at best. A sensible Charter would also probably include liaisons with disability rights organizations, groups specifying the operation of relay services, and groups considering next steps for access to emergency services. > From: iesg@xxxxxxxx > To: new-work@xxxxxxxx > Date: Fri, 26 Jun 2015 08:36:05 -0700 > Subject: [new-work] WG Review: Selection of Language for Internet Media (slim) > > A new IETF working group has been proposed in the Applications and > Real-Time Area.
