Technical Summary

   The ALTO protocol as specified in RFC 7285 allows to only query results for one single ALTO cost metric in a given ALTO request. This document specifies an extension that implements new service to allow a client to retrieve several cost metrics with one request.

Working Group Summary

  There is clear support and consensus in the ALTO WG, and it provides a very useful extension to the base ALTO protocol. A WGLC has successfully been passed, and extensive reviews were provided by various members of the WG and have all been addressed.
