-Foreword
---------
-
-This document describes application framework fundamentals.
-FCS (Fully Conform to Specification) implementation is still under development.
-It may happen that current implementation somehow diverges with specifications.
-
-Overview
---------
-
-The application framework on top of the security framework
-provides components to install and uninstall applications
-as well as to run them in a secured environment.
-
-The goal of the framework is to manage applications and hide security details
-to applications.
-
-For the reasons explained in introduction, it was choose not to reuse Tizen
-application framework directly, but to rework a new framework inspired from Tizen.
-
-fundamentals remain identical: the applications are distributed
-in a digitally signed container that should match widget specifications
-normalized by the W3C. This is described by the technical
-recommendations [widgets] and [widgets-digsig] of the W3 consortium.
-
-As today this model allows the distribution of HTML, QML and binary applications
-but it could be extended to any other class of applications.
-
-The management of widget package signatures.
-Current model is only an initial step, it might be extended in the
-future to include new feature (ie: incremental delivery).

-### Organization of directory of applications ###
+## Organization of directory of applications
The main path for applications 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
+- APPDIR is as defined above
+- PKGID is a directory whose name is the package identifier
+- VER is the version of the package MAJOR.MINOR
-The advantage of such an organization is to allow several versions to live together.
+The advantage of such an organization is to allow several versions to live together.
This is required for multiple reasons (ie: roll back) and to comply with developers habits.
-#### Identity of installed files ####
+### Identity of installed files
-All the files are installed as user "userapp" and group "userapp".
+All the files are installed as 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 files.
+### Labeling the directories of applications

-### Organization of data ###
+## Organization of data
The data of a user are contain within its directory and are labeled using the application labels
-### Setting Smack rules for the application ###
+## Setting Smack rules for the application
For Tizen, the following rules are set by the security manager for each application.
Here, ~PKG~ is the identifier of the package and ~APP~ is the identifier of the application.
-### What user can run an application? ###
+## What user can run an application`?`
-Not all user are able to run all applications.
+Not all user are able to run all applications.
How to manage that?
