           IANA Registry for RTCWeb Constrainable Properties
              draft-burnett-rtcweb-constraints-registry-05

Abstract

   Specifications in W3C's Media Capture Task Force and WebRTC Working
   Group have need of a registry in which to maintain a list of
   constrainable properties for HTML media and other constrainable
   objects.  This document defines this registry.

1.  Introduction

   There is currently one W3C specification (Media Capture and Streams
   [W3C.WD-mediacapture-streams-20130903]) that has need of a registry
   in which to represent constrainable properties, and it is expected
   that others will as well.  The specification makes use of a data
   structure representing a list of constraints on the HTML media or
   media connection to be established.  Additionally, the specification
   defines methods that are used to query the web browser about its
   capabilities.  The returned data structure specifies the browser's
   capabilities in terms of constraints that it can satisfy.  The data
   structures and their use are defined as the Constrainable interface
   in the aforementioned specification.  This document specifies the
   registry used to define individual constrainable property names,
   their allowed values, and their meanings.

2.  Requirements Language

   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].

3.  IANA Considerations

   This document defines a registry "RTCWeb Constrainable Properties"
   for use by W3C specifications needing to indicate constrainable
   properties on HTML Media and other constrainable objects, both as
   used by web application authors to indicate preferences and as used
   by web browsers to indicate constrainable properties they can
   satisfy.
