Hello,

   As a way to get the read-write-web started we want to get the simplest and most basic linked and secure social web going.

 The University of Leipzig - who are organising the Linked Data 2 - have the cool address book in Android I mentioned in a previous post here [1], as well as one that works in html5. On the server side we have
  - Joe Presbrey's data.fm
  - Alex Bertails scala based read-write-web to which I have just added WebID support (see the webid branch )
  - others want to join?

So the idea is to make it possible for these servers allow the same address book to do some of the following tasks, without knowing what is on the server:

  1- of course GET foaf, in order to walk the social web
  2- create a new directory perhaps for a user 
  3- PUT a WebID Profile there (i.e., some public foaf with a public key)
  4- Be able to update statements in that graph (say when wanting to add a new key)
  5- Create a non public foaf file
  6- add access control rules in the right place about that non public foaf file
  7- be able to notify someone when one is speaking about them - or when one wants to add a friend request


So those are some of the things that need to be done. The idea then is that we should be able to put up these servers in different universities, and allow people using the address books to develop their up-to-date social networks. 

  So as a starting point, which I am not too satisfied with I have the following test case for read-write-web
https://dvcs.w3.org/hg/read-write-web/file/9ca474c333e8/src/test/scala/auth/CreateWebIDSpec.scala

Here are some perhaps arbitrary decisions:

 1. POSTing a SPARQL query or update on an rdf resource updates it
 2. that resource should have a Link: </.meta>; rel=meta so that the client knows where it can update the metada
    if it is allowed to update it of course
 3. if that resource is an RDF query then it should be possible to update the access control to it

Btw. in my test cases I made the WebID profile only readable by myself, and was then wondering why I could not access it! :-) The server is using open http access probably and could not itself gain access to that file to test the webid...

   Anyway, I propose we discuss this a bit here, and then have a conf call sometime soon to work out which are the lowest hanging fruits we want to solve first, so that the Address Book people can implement these things, and test them against our implementations.

	Henry
