I-D Action:draft-ietf-geopriv-sip-lo-retransmission-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           : Implications of <retransmission-allowed> for SIP Location Conveyance
	Author(s)       : T. Hardie, et al.
	Filename        : draft-ietf-geopriv-sip-lo-retransmission-00.txt
	Pages           : 17
	Date            : 2008-07-03

This document explores an ambiguity in the interpretation of the
<retransmission-allowed> element of the Presence Information Data
Format for Location Objects (PIDF-LO) in cases where PIDF-LO is
conveyed by the Session Initiation Protocol (SIP).  It provides
recommendations for how the SIP location conveyance mechanism should
adapt to these ambiguities.

Documents standardizing the SIP location conveyance mechanisms will
be standards-track documents processed according to the usual SIP
process.  This document is intended primarily to provide the SIP
working group with a statement of the consensus of the GEOPRIV
working group on this topic.  It secondarily provides tutorial
information on the problem space for the general reader.

	Title           : HTTP Enabled Location Delivery (HELD)
	Author(s)       : M. Barnes, et al.
	Filename        : draft-ietf-geopriv-http-location-delivery-08.txt
	Pages           : 48
	Date            : 2008-07-10

A Layer 7 Location Configuration Protocol (L7 LCP) is described that
is used for retrieving location information from a server within an
access network.  The protocol includes options for retrieving
location information in two forms: by value and by reference.  The
protocol is an extensible application-layer protocol that is
independent of session-layer.  This document describes the use of
HyperText Transfer Protocol (HTTP) and HTTP over Transport Layer
Security (HTTP/TLS) as transports for the protocol.

This draft is a work item of the Geographic Location/Privacy Working Group of the IETF.

	Title           : Discovering the Local Location Information Server (LIS)
	Author(s)       : M. Thomson, J. Winterbottom
	Filename        : draft-ietf-geopriv-lis-discovery-02.txt
	Pages           : 27
	Date            : 2008-07-10

A method is described for the discovery of a Location Information
Server.  The method uses a Dynamic Host Configuration Protocol (DHCP)
option.  DHCP options are defined for both IPv4 and IPv6 DHCP.  A
URI-enabled NAPTR (U-NAPTR) method is described for use where the
DHCP option is unsuccessful.  This document defines a U-NAPTR
Application Service for a LIS, with a specific Application Protocol
for the HTTP Enabled Location Delivery (HELD) protocol.  The held:
URI scheme, the product of the discovery process, is defined by this
document.

	Title           : A Document Format for Filtering and Reporting Location Notications in the Presence Information

This document describes filters which limit asynchronous location
notifications to compelling events.  The resulting location
information is conveyed in existing location formats wrapped in
GEOPRIV privacy extensions to the Presence Information Document
Format (PIDF-LO)

RE: Review of draft-ietf-geopriv-http-location-delivery-07

Hi Eric,

I've snipped the thread to just include the issues (3 total) that I'm
uncertain as to whether they've been adequately addressed in the -08:

Thanks,

Items of cross group interest

This message is heavily crossposted. It is set to reply-to geopriv.
If you manually reply-to, please reply there.

There are some questions about how to best provide location for some  
applications. To date, the answer from GEOPRIV has been to use  
Presence as defined by SIMPLE and extended by GEOPRIV. (We've spent  
time arguing that in GEOPRIV more than once).

There are some new proposals, perhaps with new information, that push  
at that answer again, and in some cases, if they move forward, its not  
clear what the best venue to vet them in is. But we have to start  
somewhere, and the plan at the moment is to have a framing discussion  
in GEOPRIV.

Please review the following drafts, comment on the GEOPRIV list if you  
have an opinion, and plan to attend this section of the GEOPRIV  
meeting if you have an interest in how the conversation turns out.

GEOPRIV and ECRIT experiments at IETF 72

I wanted to let folks know about an experiment that some folks from the
GEOPRIV and ECRIT working groups have been working to set up at IETF 71 
to see if we can deliver some basic location-based applications 
(including emergency calling), using the IETF network as a platform.

The prinicpal challenge in creating location-based applications is 
getting location in the first place.  This experiment is getting 
location via the IETF network: When you send the location server a 
request for your location, it looks up which AP you're connected to and 
returns the location of that AP (if it knows it).

Based on this location platform, we've created a few different 
applications, including
-- Basic location mapping
-- ECRIT emergency calling
-- Location-enhanced Jabber presence
-- LoST-based discovery of nearby points of interest (e.g., museums)

Much more information is available on the web page we've created at the 
following URI:
<http://geopriv.googlepages.com/>

Please feel free to send email to me if you're interested in 
participating or helping out in any way, or if you have any feedback on 
the experiment.

Thanks
--Richard

Chillout, IETF#72

In case you are still in Dublin on Friday evening and if you are 
interested to hang around with other IETF folks please drop me a note.
