Introduction

These are some pages under development to document the Protege 4 Server. We are hoping to release an early alpha soon. <p/>

Videos

Here is the first of several videos that I am going to make to demonstrate server features:

• Protege OWL Client-Server Basics

Installation details

The purpose of these pages is to allow people to know what is installed by the server installation and what options the user can change. The installation setup is slightly different depending on whether the operating system in question is Linux, OS X or Windows. The Protege Server should run on other platforms as well though we don't yet support its installation. The key things that need to be figured out for an installation to some other platform is obtaining a version of Java that is at least Java 1.6 and determining how to make the Protege 4 Server start at boot time.

Linux

On a linux system the following files and directories are created:

• /usr/local/protege which contains the core server installation in the subdirectory server, the users data files in the subdirectory data and some command line utilities in the bin subdirectory.
• /etc/init.d/protege which is a script that ensures that the Protege server is started at boot time.
• /etc/default/protege which is a properties file that configures the init.d script above. The user will have to modify this file before the server will run correctly.

An example/etc/default/protege file looks like this:

#
# This file goes into /etc/default/protege and holds the default
# settings for the Protege Server.
#

HOSTNAME=`hostname`
PROTEGE_SERVER_PREFIX=/usr/local/protege
PROTEGE_SANDBOX_USER=tredmond
JAVA_CMD=/usr/local/java/jdk1.7.0_06/bin/java
PID=/var/log/protege/PID

The HOSTNAME property tells the Protege 4 server
