1.  Introduction

   This document profiles the Metadata Query Protocol
   [I-D.young-md-query] for use with SAML metadata [SAML2Meta].

   The Research and Education Federations group ([REFEDS]) is the voice
   that articulates the mutual needs of research and education identity
   federations worldwide.  It aims to represent the requirements of
   research and education in the ever-growing space of access and
   identity management.

   From time to time REFEDS will wish to publish a document in the
   Internet RFC series.  Such documents will be published as part of the
   RFC Independent Submission Stream [RFC4844]; however the REFEDS
   working group sign-off process will have been followed for these
   documents, as described in the REFEDS Participant's Agreement
   [REFEDS.agreement].

   This document is a product of the REFEDS Working Group process.
