Abstract

   This document creates a registry for describing the types of services
   available at a specific location.  The registry is expected to be
   referenced by other protocols that need a common set of service terms

   as protocol constants.  In particular, we define location-based
   service as either a point at a specific geographic location (e.g.,
   bus stop) or a service covering a specific region (e.g., pizza
   delivery).

1.  Introduction

   Many mobile devices are now equipped to determine the user's
   geographic location, either through GPS, cell-tower mapping or a
   network-based triangulation mechanism.  Once location information is
   available, it is natural to want to look up near-by places that
   provide a specific service, sometimes called points-of-interest
   (POI).  Examples of such services include restaurants, stores,
   hospitals, automatic teller machines and museums.

   To allow such systems to operate across large geographic areas and
   for multiple languages, it is useful to define a common set of terms,
   so that the same service is labeled with the same token regardless of
   who created a particular location service.  The number of different
   labels is clearly potentially very large, but only a relatively small
   subset of common services is of particular interest to mobile users,
   such as travelers and commuters.  This document focuses on labels
   commonly found on maps or in navigation devices.

   This document creates a registry of service labels and an initial set
   of values.  The registry is protocol-agnostic and should work for all
   protocols that can handle alphanumeric strings, including LoST
   [RFC5222].

2.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
