A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Geographic Location/Privacy Working Group of the IETF.


	Title           : GEOPRIV PIDF-LO Usage Clarification, Considerations and Recommendations
	Author(s)       : J. Winterbottom, et al.

The Presence Information Data Format Location Object (PIDF-LO)
specification provides a flexible and versatile means to represent
location information.  There are, however, circumstances that arise
when information needs to be constrained in how it is represented.
In these circumstances the range of options that need to be
implemented are reduced.  There is growing interest in being able to
use location information contained in a PIDF-LO for routing
applications.  To allow successful interoperability between
applications, location information needs to be normative and more
tightly constrained than is currently specified in the RFC 4119
(PIDF-LO).  This document makes recommendations on how to constrain,
represent and interpret locations in a PIDF-LO.  It further
recommends a subset of GML that is mandatory to implement by
applications involved in location based routing.

NOTE:   The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
