Abstract

   A Thing-to-Thing Bulletin Board is a RESTful, hypermedia-driven Web
   application that can be used in Thing-to-Thing communication to
   publish information such as thing descriptions, configurations,
   resource descriptions or sleep schedules at a central location.

1.  Introduction

   The CoRE Lighting [I-D.hartke-core-lighting] draft defines a
   "bulletin board" application that can be used for sharing the thing
   descriptions of sensor and actuator nodes.  This document generalizes
   the bulletin board to support representations in any media type and
   defines means for creating, reading, observing, updating, deleting
   and finding items in a bulletin board.

   The generalization to any media type provides two advantages: The
   first is media type agility: applications won't be stuck forever with
   the media types of CoRE Lighting.  The second is that it may be
   useful to share also other information than thing descriptions, such
   as default configurations for new devices, service locations or sleep
   schedules.

   Findings items is a powerful mechanism for retrieving a subset of
   items from a bulletin board.  In CoRE Lighting, a configurator has to
   download the whole set of thing descriptions, filter the set and
   configure compatible devices.  It may be more efficient to filter the
   set at the bulletin board server.  To make this work with any media
   type, a search request needs to specify both the media type of the
   desired items and a media type-specific filter query.

   The generalized bulletin board is presented as a CoRE Application
   Description [I-D.hartke-core-apps].  That is, the focus of the
