I'd better explain the specific implementation. Anyone's profile page is
viewable on the web by anyone. But you can specify if the detail is
hidden. You can also hide parts of the data such as email address, real
address and phone numbers. The FOAF data for this followed the same
rules so the same data is available to anyone in XML or HTML.
Your network of friends is available to anyone who's logged in.
Initially I exposed this as well as XML but still obeying the same rules
as above for each friend. This means that data that was only available
to logged in members was now available in XML which is probably a step
too far. What I ought to do is to have some authentication in the XML
URL but I'm unsure of how to do this "properly". As a short cut I've now
added a switch to say whether your detail is exposed in XML and it only
shows friends who have also turned on this switch.
Most of the complaints from the active members were not really about
this FOAF XML at all. Rather they were about the philosophy behind it
and they're feelings about exposing their rolodex to the world. This is
partly because these are people who make money from their rolodex and
hence see it as a valuable personal possession not to be shared. This is
almost diametrically opposed to the geek position ;-) of JFDI!
What's a bit sad about all this is that I threw the code up to stimulate
debate about what we would do with it, not to argue about the code
itself. My Bad!
I've also pointed Adrian Scott of Ryze at the FOAF web pages and he
seems interested. Ryze has the same issues in that the profile page is
publicly accessible but the friends list is only visible once you've
