Presence and IntComm WG

[Candace Holman <>]

Dear PIC Members,

Based on yesterday's conference discussion, I've made some updates to the 
requirements list for packaging presence for longer term trials.  Please 
review and post any modifications or questions.  I've listed some names 
with some tasks, please check to see if this is correct, or let me know if 
you're interested in helping with unassigned tasks.

Truly,
Candace

Requirements for Longer Term PALS Trial Packaging
12/20/04

Updates
-------
02/25/05 - Phase 1 packaging refinements for Spring MM

Introduction
------------
All members of the working group invite longer term trial participation - 
hopefully from schools, hospitals, and other institutions that have a 
predetermined desire for presence technologies.  However, we realize that 
it is difficult to sell the idea of a trial without a package.  This 
document starts the process of packaging a presence trial based on current 
client and server implementations.

To package a trial we have to agree on the basic representation of a trial. 
This initial document assumes that we will provide documentation, server 
code, and installation and simulation scripts to potential trial 
participants.  For Phase 1 packaging, we will most likely develop a basic 
ser/pa RPM set; suggest the use of SIP.edu; provide documentation for 
installation, user provisioning and testing; and provide recommendations 
for at least two clients that support audio, presence, and IM.

The rest of the document describes a semi-chronological listing of tasks to 
support Longer Term Trial Packaging.


Preliminaries
-------------
Agree upon several scenarios for longer term trial deployment - choose from 
each category:
a. Servers: SIP.edu service, I2 PALS server, Local ser/pa server configured 
by PIC-WG script
(Phase 2+: Local ser/pa server customized for local use, Local custom 
(geopriv-based?) location server)
b. Data collection: manual (Phase 2+: HP Skiffs, custom solutions based on 
APs, manual PUBLISH)
c. Data Aggregation:  none (Phase 2+: HP Data Aggregator, custom solutions)
d. Client: choose 2 that do audio, basic presence and IM, and make sure 
there is an option for Macs.  Xten eyeBeam, pulver Communicator, wavethree 
Session, etc (Phase 2+: video, group presence, rich presence)
e. Protocol options: XCAP/PIDF, PUBLISH
f. Client modes: IM, rich-presence, sip-voice (Phase 2+: gatewayed-voice, 
and/or video)
g. User provisioning modes: manual (Phase 2+: ldap)

Research (Jamey?)
--------
Determine basic components of an ser/pa install, including:
- configure network settings
- configure access control
- configure user accounts
- configure maps and access point locations (?)

Server
------
in progress: Stabilize the current PA version to most recent chosen RFCs/I-Ds
todo: Create bug list, prioritize solutions, enlist help
in progress: Ensure the current stable version is available in the ser cvs 
repository
todo: Create RPMs for closest approximation of one-button setup
todo: Testing installation instructions and RPMs outside of 
pals.internet2.edu (Jeremy, Art)

Client
------
done: Cannot use SIPc for basic IM and Voice because of licensing
in-progress: Find some other clients that use the PUBLISH method for 
presence/loc updates
in-progress: Create bug list, prioritize solutions, enlist help

Loc/Presence Aggregation (not required for Phase 1)
------------------------
done: Determine intellectual property rights of current package
todecide: Possibly create a middleware system to do RFC3903 (event  stuff
todecide: Determine standard map image upload and mapped location tracking 
requirements

Coding
------
todo: Write script that tests the PUBLISH capability of PALS, confirms 
local network viability like a basic echo test (Candace)
todo: Write RPMs for the ser server and pa module

Documentation
-------------
in-progress: Write a document about presence/location data handling in the 
PA module
- methods and hardware to publish data
- methods to gather and aggregate data
- how to test virtual location aggregation

todo: Update Jamey and Xiaotaow's client requirements document
todo: Write a server requirements document
todo: Write an "adherance to current standards" document
