RE: combination of location and identity

Greetings - this is an extremely interesting and timely topic of
discussion. I look forward to this WG providing invaluable guidance
on ways to deal with the sensitivities of individuals that wish to
have their privacy and security maintained.

As most of you may know the Open GIS Consortium has been and
continues to be vitally interested in the extension of location
information and related services from the infrastructure to the
wireless platform over internet communication pathways.

The WG has devoted the month of July to requirements collection, and
recent emails have raised some fundamental questions concerning
location representations and common understanding about what are
location-based services.

I would like to point WG participants to a URL where you can find
considerable technical information that address questions and
comments posed by Mssrs. Valentin, Hauser, Takahashi and others.
Several days ago the Consortium issued a Call for Participation for
the Open Location Services Testbed. This testbed is open to all. The
Call documents (particularly Annex A) contains technical foundation
information, albeit from an applications perspective, that may relate
to IETF i-d requirements work underway and it is offered as a
resource document for IETF's use.

Annex A presents the architecture for the testbed. The architecture
is based upon a collaborative effort between OpenLS Sponsors
(Hutchison 3G, Sun Microsystems, Oracle with Webraska, ESRI with
SignalSoft and In-Q-Tel) and OGC's OpenLS engineers. The architecture
team used a variety of sources for the preparation of this document,
including: documentation and suggestions from OGC members, results
from previous and ongoing OGC testbeds and pilots, existing OGC
specifications, and publicly available documentation from related
standards initiatives (Parlay, LIF, JAIN, WAP, W3C, and MAGIC).

Section 2 provides definitions for many key terms.

Section 3 describes the Operational Architecture for location
services. Here we describe the high-level system concept and present
representative use cases that illustrate the end-to-end utility of
the Open Location Services Platform defined herein.

Section 4 describes the Open Location Services Platform (a technical
architecture). This architecture is described in terms of two
complimentary perspectives: the Services Framework and the
Information Framework. The Services Framework identifies and
describes the foundational service building blocks of the Open
Location Services Platform. The Information Framework describes the
foundational data/content building blocks of the Open Location
Services Platform.

Section 5 provides a brief discussion on related standards.

Section 6 provides a summary of the services that will be developed
under this project.

I hope this proves helpful so that the work of developing the
necessary privacy and security specs can move out as rapidly as
possible.
