Foreword
--------
-This document describes what we intend to do. It may happen that our
-current implementation and the content of this document differ.
-
-In case of differences, it is assumed that this document is right
-and the implementation is wrong.
-
+This document describes application framework fundamentals.
+FCF (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 the components to install and uninstall applications
-and to run it in a secured environment.
+provides components to install and uninstall applications
+as well as to run them in a secured environment.
-The goal is to manage applications and to hide the details of
-the security framework to the applications.
+The goal of the framework is to manage applications and hide security details
+to applications.
-For the reasons explained in introduction, we did not used the
-application framework of Tizen as is but used an adaptation of it.
+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.
-The basis is kept identical: the applications are distributed
-in a digitally signed container that must match the specifications
-of widgets (web applications). This is described by the technical
-recomendations [widgets] and [widgets-digsig] of the W3 consortium.
+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.
-This model allows the distribution of HTML, QML and binary applications.
+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 signatures of the widget packages
-This basis is not meant as being rigid and it can be extended in the
-futur to include for example incremental delivery.
+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).
Comparison to other frameworks
### ostro
-Organisation of directory of applications
+organization of directory of applications
=========================================
-The main path for applivcations are: APPDIR/PKGID/VER.
+The main path for applications are: APPDIR/PKGID/VER.
Where:
- 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).
+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
---------------------------
-All the files are installed as the 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 the files.
+This allows any user to read files.
-Labelling the directories of applications
+labeling the directories of applications
-----------------------------------------
-Organisation of data
+organization of data
====================
-The data of a user are in its directory and are labelled using the labels of the application
+The data of a user are contain within its directory and are labeled using the application labels
Setting Smack rules for the application
