1 to 1 chat #22

We have to resolve to issues

1. discovery of the chat url --> private typeIndex of each party
2. user notifications of chat one2one chat URL --> (?) chatInvite to inbox
3. chat ressources permissions --> ACL

A solution is with using chatRoot/.acl and privateIndex on each side.
You should have :

• create private chat with
  • a query for webId of the otherParty
  • storing the chat link in owner privateIndex (logged-in)
  • create chatRoot/.acl
    • owner with Read Append Control or Read Append Write
    • restricted with Read Append for the other chat party

@prefix : <#>.
@prefix acl: <http://www.w3.org/ns/auth/acl#>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.
@prefix tes: <./>.
@prefix c: </profile/card#>.

:AppendRead
    a acl:Authorization;
    acl:accessTo tes:;
    acl:agent <an agent webid>;
    acl:default tes:;
    acl:mode acl:Append, acl:Read.
:AppendControlRead
    a acl:Authorization;
    acl:accessTo tes:;
    acl:agent c:me;
    acl:default tes:;
    acl:mode acl:Control, acl:Read, acl:Append.

• You can send an chatInvite in the otherParty inbox
• join to a privateChat
  • asking for chatLink to join
  • and storing the link in the logged-in user privateIndex
