   4 - xdg-app
   5 - ostro

   7 ## Organization of directory of applications
   8
   9 The main path for applications are: APPDIR/PKGID/VER.
  10
  11 Where:
  12
  13 - APPDIR is as defined above
  14 - PKGID is a directory whose name is the package identifier
  15 - VER is the version of the package MAJOR.MINOR
  16
  17 The advantage of such an organization is to allow several versions to live together.
  18 This is required for multiple reasons (ie: roll back) and to comply with developers habits.
  19
  20 ### Identity of installed files
  21
  22 All the files are installed as user "userapp" and group "userapp".
  23 All files have rw(x) for user and r-(x) for group and others.
  24
  25 This allows any user to read files.
  26
  27 ### Labeling the directories of applications
  28
  29 ## Organization of data
  30
  31 The data of a user are contain within its directory and are labeled using the application labels
  32
  33 ## Setting Smack rules for the application
  34
  35 For Tizen, the following rules are set by the security manager for each application.
  36
  37     System ~APP~             rwx
  38     System ~PKG~             rwxat
  39     System ~PKG~::RO         rwxat
  40     ~APP~  System            wx
  41     ~APP~  System::Shared    rxl
  42     ~APP~  System::Run       rwxat
  43     ~APP~  System::Log       rwxa
  44     ~APP~  _                 l
  45     User   ~APP~             rwx
  46     User   ~PKG~             rwxat
  47     User   ~PKG~::RO         rwxat
  48     ~APP~  User              wx
  49     ~APP~  User::Home        rxl
  50     ~APP~  User::App::Shared rwxat
  51     ~APP~  ~PKG~             rwxat
  52     ~APP~  ~PKG~::RO         rxl
  53
  54 Here, ~PKG~ is the identifier of the package and ~APP~ is the identifier of the application.
  55
  56 ## What user can run an application`?`
  57
  58 Not all user are able to run all applications.
  59 How to manage that?
