Re: CC/PP Implementation

Not at all. Those are good questions.

The "Implementation guidelines" unfortunately only exists in various states
of bits and pieces right now. We have not been able to create the actual
document, even though we have had several editors give it a try (I guess
they were too busy implementing :-) ).

However, on the working group mailing list (which you can access, since you
are a member) there are references to implementations by SBC and Keio
University. Ericsson has also done an implementation, which is commercially
available (so you may be able to learn more from SBC or Keio, depending on
how you want to work it).

In my view, there are three things you need to do (and a lot of "that
depends", as you will see).

1. Implement the CC/PP-ex protocol on the client.
2. Implement the CC/PP-ex protocol on the server
Alternative to 1 and 2: Tweak one of the HTTP headers, e.g. user-agent, and
use that to transport information. But it will only work for research
purposes - as will using POST.
3. Implement a heuristic to select/compose document(s) based on CC/PP on the
server. This piece is non-standardized, since it is beyond the scope of the
working group. Essentially, I think you have to create an inference based on
the profile and some built-in heuristics to select documents. One
(minimalistic) way of doing it is to tweak the content negotiation.
4. Run it and tell us if it worked.

Now, this is my personal view, and others may have taken different paths.

I believe there will also be a number of talks about this at WWW10, which I
think will be useful to attend.
