+The afm-system-daemon
+=====================
+
+    version: 1
+    Date:    14 March 2016
+    Author:  José Bollo
+
+
+Organisation of directory of applications
+=========================================
+
+The main path for applivcations are: APPDIR/PKGID/VER.
+
+Where:
+
+ - APPDIR is as defined above
+ - PKGID is a directory whose name is the package identifier
+ - VER is the version of the package MAJOR.MINOR
+
+This organisation has the advantage to allow several versions to leave together.
+This is needed for some good reasons (rolling back) and also for less good reasons (user habits).
+
+Identity of installed files
+---------------------------
+
+All the files are installed as the user "userapp" and group "userapp".
+All files have rw(x) for user and r-(x) for group and others.
+
+This allows any user to read the files.
+
+
+Labelling the directories of applications
+-----------------------------------------
+
+
+Organisation of data
+====================
+
+The data of a user are in its directory and are labelled using the labels of the application
+
+Setting Smack rules for the application
+=======================================
+
+For Tizen, the following rules are set by the security manager for each application.
+
+    System ~APP~             rwx
+    System ~PKG~             rwxat
+    System ~PKG~::RO         rwxat
+    ~APP~  System            wx
+    ~APP~  System::Shared    rxl
+    ~APP~  System::Run       rwxat
+    ~APP~  System::Log       rwxa
+    ~APP~  _                 l
+    User   ~APP~             rwx
+    User   ~PKG~             rwxat
+    User   ~PKG~::RO         rwxat
+    ~APP~  User              wx
+    ~APP~  User::Home        rxl
+    ~APP~  User::App::Shared rwxat
+    ~APP~  ~PKG~             rwxat
+    ~APP~  ~PKG~::RO         rxl
+
+Here, ~PKG~ is the identifier of the package and ~APP~ is the identifier of the application.
+
+What user can run an application?
+=================================
+
+Not all user are able to run all applications.
+How to manage that?
