        The Named Information (ni) URI Scheme: Optional Features
                 draft-hallambaker-decade-ni-params-02

Abstract

   This document specifies optional things that one can do with "ni"
   URIs and related names.  Those include an additional hash algorithm
   for handling dynamic content, some specific query-strong parameters
   for ni URIs and a mechanism for embedding ni URIs into QR codes.

1.  Introduction

   The ni URI scheme [nischeme] supports extensibility in terms of the
   algorithm used to derive a value (normally, but not always a strong
   digest algorithm) and via support for a query-string thay can contain
   a list of key=value pairs.  This document defines some uses for both
   of these extensibility points and creates IANA registries that can be
   used to register additional algorithms and key strings for use in the
   query part of an ni name.  We [[will]] also define a way to embed ni
   names in QR codes.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   [[Comments are included in double-square brackets, like this.]]

   [[Note that the features here are less mature than the specification
   in the [nischeme] document.  The intent is to develop these as
