Yesterday during the GIS SC teleconference I mentioned that there are a
number of IETF RFCs that could have an impact/synergy with the work of this TC.
The majority of the work by the IETF membership WRT location has to do with
either delivery of services in an EM siutation or 2.) protection of privacy and
privacy encoding rules for location payloads on the internet.
I am enclosing information on a number of recent RFC
submissions/updates.

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 : A Presence-based GEOPRIV Location
Object Format Author(s) : J. Peterson Filename :
draft-ietf-geopriv-pidf-lo-02.txt Pages : 24 Date : 2004-6-30 This
document describes an object format for carrying geographical
information on the Internet. This location object extends
the Presence Information Data Format (PIDF), which was designed
for communicating privacy-sensitive presence information and
which has similar properties. A URL for this

A New Internet-Draft is available from the on-line Internet-Drafts
directories. This draft is a work item of the Session Initiation Proposal
Investigation Working Group of the IETF. Title : Requirements for Session
Initiation Protocol Location Conveyance Author(s) : J. Polk, B.
Rosen Filename : draft-ietf-sipping-location-requirements-01.txt Pages :
45 Date : 2004-7-19 This document presents the framework and
requirements for usage of the Session Initiation Protocol (SIP)
[RFC 3261] to convey user location information from a Session
Initiation Protocol (SIP) user agent to another SIP
entity. We consider cases where location information is
conveyed from end to end, as well as cases where message
routing by intermediaries is influenced by the location of the
session initiator. We offer a set of solutions to the
requirements, based on the scenario(s) being addressed. A URL for this

directories. This draft is a work item of the Geographic Location/Privacy
Working Group of the IETF. Title : A Document Format for Expressing
Privacy Preferences Author(s) : H. Schulzrinne, et al. Filename :
draft-ietf-geopriv-common-policy-01.txt Pages : 40 Date :
2004-7-21 This document defines a framework for authorization
policies controling access to application specific data. This
framework combines common location- and SIP-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. A

directories. Title : Advertising Interactive Connectivity
Establishment (ICE) Services with Presence Author(s) : J.
Peterson Filename : draft-peterson-pidf-ice-00.txt Pages : 10 Date :
2004-7-13 Many presence applications use availability information about
a presentity to show a watcher their readiness to
communicate. In the case of real-time multimedia
communications, the readiness of the presentity to communicate
does not entail that the network topography will permit
communication to occur. Accordingly, this document
specifies a means to integrate Interactive Connectivity
Establishment (ICE) with presence. Presentities employing
the Presence Information Data Format (PIDF) can use the
extensions in this draft to advertise their ability to undergo a
preliminary ICE check, and thus allow watchers to instigate ICE
tests to ascertain whether or not the intervening network is
friendly to real-time multimedia communication. In a
presence application, the results of this test could be
displayed to watchers as the relative "connectivity status" of
the presentity. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-peterson-pidf-ice-00.txtOGC: Helping the world to communicate geographically...
