Subject: RE: IETF work related to work of this TC
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.

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.

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.

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.
