I-D ACTION:draft-ietf-geopriv-pdif-lo-profile-00.txt

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)	: H. Tschofenig, et al.
	Filename	: draft-ietf-geopriv-pdif-lo-profile-00.txt
	Pages		: 31
	Date		: 2005-7-5
	
   The GeoPriv 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 so that the number of options that need to be
   implemented in order to make use of it are reduced.  There is growing
   interest in being able to use location information contained in a
   PIDF-LO for message and call routing applications.  For such
   applications to interoperate successfully location information will
   need to be normative and more constrained than is currently described
   in the PIDF-LO specification.  This paper makes recommendations on
   how to constrain, represent and interpret locations in a PIDF-LO.  It
   further looks at existing communications standards that make use of
   geodetic information for routing purposes and recommends a subset of
   GML that MUST be implemented by applications to allow message routing
   to occur.

RFC 4079 on A Presence Architecture for the Distribution of GEOPRIV Location Objects


A new Request for Comments is now available in online RFC libraries.

        RFC 4079

        Title:      A Presence Architecture for the
                    Distribution of GEOPRIV Location Objects
        Author(s):  J. Peterson
        Status:     Informational
        Date:       July 2005
        Mailbox:    jon.peterson <at> neustar.biz
        Pages:      7
        Characters: 16718
        Updates/Obsoletes/SeeAlso:    None

        I-D Tag:    draft-ietf-geopriv-pres-02.txt

        URL:        ftp://ftp.rfc-editor.org/in-notes/rfc4079.txt

GEOPRIV defines the concept of a 'using protocol' -- a protocol that
carries GEOPRIV location objects.  GEOPRIV also defines various
scenarios for the distribution of location objects that require the
concepts of subscriptions and asynchronous notifications.  This
document examines some existing IETF work on the concept of presence,
shows how presence architectures map onto GEOPRIV architectures, and
moreover demonstrates that tools already developed for presence could
be reused to simplify the standardization and implementation of
GEOPRIV.

This document is a product of the Geographic Location/Privacy Working

PIDF-LO and the presence data model

There doesn't seem to be any real specification indicating how exactly 
PIDF-LO and the SIMPLE presence data model interact.

draft-ietf-geopriv-pidf-lo-03 just gives an example, putting it in 
<status> within <tuple>. From the perspective of the data model, that's 
probably the least-liekly place - tuples represent services and seem the 
least related to one one location, compared to devices (presumably 
always have exactly one location) and persons (one true location, 
despite attempts by people to be in two places at the same time).

If a user has multiple service (tuples), it seems odd to have one random 
one indicate a location, or, worse, two conflicting ones.

RFC 4079 describes general architecture, not really protocol bits.

So far, the Data Model draft doesn't mention PIDF-LO.

Did I miss a precise specification anywhere?

Maybe the data model should address this; I'm also happy to add this to 
RPID, but that seems more of a stretch.

This document defines a framework for authorization policies
   controling access to application specific data.  This framework
   combines common location- and presence-specific authorization
   aspects.  An XML schema specifies the language in which common policy
   rules are represented.  The common policy framework can be extended
   to other application domains.
