Introduction
The Axiomatics Language for Authorization (ALFA) is a
domain-specic language for a high-level
description of XACML policies. It is designed for ease of use by
developers. In addition, it presents
domain specic information such as attribute identiers in compact
form and it can be compiled into
XACML 3.0.
This document explains how to install it.
Conventions
On Microsoft Windows, the actual path separator is the backslash
character (\) and on Linux the forward
slash (/).
Throughout this guide, the forward slash is used to denote a le
system path separator although the actual
separator may be different on the target platform.
Prerequisites
An editor and compiler for ALFA are delivered as an Eclipse
plugin. ALFA has been tested with the

ALFA may work with other architectures but it has only been
tested with those listed above.
Note: The following step is needed only for Eclipse Indigo.
Later versions do not require it.
The ALFA Plugin for Eclipse has a dependency on the Xtext
library, so the following update site must be
enabled in your eclipse conguration:
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/
This is done in Eclipse on the menu Help -> Install New
Software
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/

Testing the ALFA plugin
The ALFA plugin for Eclipse is now installed. To try it out,
create a new project in Eclipse and make a
folder called src. Then create a le with the extension alfa, for
instance test.alfa, in the src folder.
Eclipse will ask you to add the Xtext nature to the project.
Select yes.
Copy the le system.alfa from the ALFA distribution into the
project. This le contains denitions for the
standard XACML functions. Next put the le called
standard-attributes.alfa into the project. It contains
attribute ID denitions for the standard attributes from the
XACML specication.
Enter the following text into the le test.alfa:

The compiler should have produced an XML le with an XACML policy
in a folder called src-gen.
