The IESG contact persons are Jon Peterson and Cullen Jennings. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ecrit-lost-10.txt Technical Summary This document describes an XML-based protocol for mapping service identifiers and geodetic or civic location information to service contact URIs. In particular, it can be used to determine the location-appropriate PSAP for emergency services. Working Group Summary There is consensus in the WG to publish this document. Protocol Quality The LoST protocol has been implemented during the development of the specification. Two public implementations are available and other company-internal implementations have been reported to the chairs. Tests have been performed between two public implementations and useful feedback was provided to the working group. The LoST specification has experienced extensive review, including reviews by other SDOs. The protocol is an important building block in the NENA i3 architecture.
