P3P Interoperability Testing Day Agenda

21 June 2000
32 Avenue of the Americas, New York, NY

**20 June,1-5 pm setup and rehearsal [for all 10:30-11:15 demonstrators]**

(agenda subject to minor changes)

10:00 - 12:30 Public Presentation and Interoperability Demonstrations

10:00 - 10:10: Welcome, Daniel Weitzner, W3C

10:10 - 10:30: Introduction to P3P, P3P Spec and POWG WG Chairs

• Harriet Pearson, IBM -- Why P3P is important
• Deirdre Mulligan, CDT -- History and Background
• Lorrie Cranor, AT&T -- P3P in a nutshell and demo

10:30 - 11:45: Interoperability Demonstrations

• Reading a single policy: Simple Client - Server interaction
• Comparing policies on multiple sites - showing off various site policies
• Configuring a site to be P3P compliant: statement generator, posting P3P on a site, viewing policy with one or more user agents.

Seven 10-minute demos from companies who have implemented P3P

11:45 - 12:15Q&A

12:15- 1:30 Open P3P Interop demo & idea exchange and lunch

Interoperable implementation demos -- A table will be setup for people to bring laptops to demo interoperable P3P implementations (based on May 10 P3P working draft). Internet connections will be provided at this table. User agents should work properly with W3C testbed and with policies provided by participating companies. W3C staff will setup a testbed by June 9 so companies can test their user agent implementations against a variety of P3P policies. They will also setup web-based validators for P3P policies and policy reference files and create a web site with pointers to P3P policies posted by participants. Implementors must send us a one paragraph description of what they will present to w3c-p3p-interopcall@w3.org by June 5.

P3P demos and idea exchange -- People with P3P implementation plans may bring laptops to demo partial implementations or posters to illustrate implementation plans. These demos and posters may include ideas in their preliminary stages that implementors are looking for feedback on. Posters should be mounted on a foam core board or other stiff board (posters must stand by themselves on a tabletop or stand on a table or the floor and lean against a wall). Presenters may bring an easel to display their posters, but freestanding exhibit booths will not be permitted. Implementors must send us a one paragraph description of what they will present to w3c-p3p-interopcall@w3.org by June 5.

1:30-4:30 pm -- P3P Specification Working Group Open Meeting

The P3P Specification Working Group will hold a meeting to discuss the demos shown at the interop. Implementors and observers are invited to participate. This will be a working meeting to exchange implementation ideas, discuss whether further modifications to the P3P specification are needed, and discuss whether further documentation for P3P is needed (in the spec or in separate guidelines documents). This meeting will also include a discussion of open issues that have already been raised.

1. Review of demos from morning session (demos will still be setup so we can look at them again if we want).
   • Evaluation of each implementation based on interop testing criteria
   • Questions and feedback for implementors
   • Generate list of issues for Specification Working Group to address
2. Presentation and discussion of A P3P Preference Exchange Language (APPEL). We need feedback on how to proceed with APPEL. Should we continue to work on it? Does it need major changes or should we push it to last call in its current form?
3. Previously raised issues (as time permits)
   • Implementation guides -- what sort of implementation guides are needed? Which ones should be the group's top priority?
   • Is it necessary to allow web sites to use the HTTP header extension mechanism to advertise the location of their policy reference files (or are p3p.xml file and HTML LINK tag methods sufficient)?
   • Inline policies and policy summaries
   • Should we define a P3P content type as suggested in Tom Hubbard's public comment?
   • Should we add a new guiding principle about informing users about changes to a site's policy and not retroactively changing how it handles data already collected? Suggested by Noboru Shimizu
   • Are additional changes to the P3P vocabulary needed? (Are there policies that cannot be adequately expressed with the current vocabulary?)
4. New issues (as time permits)
