BIM property server

ASI - Propertyserver

This repository contains the source code of the BIM property server of Austria.

The ASI - Propertyserver is used by Austrian Standards International and is part of the ÖNORM A 6241-2.

It has been (and will be further) developed by DBIS - Databases and Information Systems of the University of Innsbruck, Department of Computer Science. It has been (and is currently) funded by the Tyrolean Regional Government via three consequent projects:

• freeBIM
• freeBIM 2
• freeBIM - connect

The ASI - Propertyserver is therefore also known as the 'freeBIM-Propertyserver'.

You will find more information about the project and all project partners at: https://www.freebim.at (in german)

You'll find a running instance of this application at: http://db.freebim.at

Setting up the project

Create a directory for the project, we'll use <BASEDIR> for this directory in this document.

$ mkdir <BASEDIR>
$ cd <BASEDIR>

GIT-Clone the project:

$ git clone https://github.com/asi-propertyserver/source.git

Adjust the properties

$ cd source/freebim-parent/freebim-webapp/src/main/resources
$ ls
application.properties	freebim.properties	log4j.properties

In the freebim.properties -file you will find the admin, neo4j and backup configuration.
You should set a new password for the admin user at least.

Javascript minifier

A C-program is used to minify the javascript files. Since it was compiled under Mac OS it may be possible that it does not work on your machine. Just check the output when building. It says something like, there is a format error in the jsmin.exe-file. When you encounter this problem just use gcc to compile source/freebim-parent/freebim-webapp/jsmin.c and replace the jsmin.exe file. To make sure everything works on your first run, you can do this also beforehand.

Logging

Create a file asi-propertyserver.log in the /var/log/ directory or adjust the logging configuration in the log4j.properties - file.

Build the application

cd into the freebim-parent project to build the application.

$ cd <BASEDIR>/source/freebim-parent
$ mvn clean -Prelease javadoc:javadoc install

Maven will automatically run all the Unit-Tests of the project. Execution of Unit-Tests could be disabled by passing an additional argument to Maven:

$ mvn clean -Prelease javadoc:javadoc install -Dmaven.test.skip=true

Maven will build the sub-projects and create the final ROOT.war file in the target directory of the freebim-webapp project. This file can now be deployed to an existing tomcat.

$ ls freebim-webapp/target/
ROOT			antrun			generated-sources	javadoc-bundle-options	maven-status		surefire		test-classes
ROOT.war		classes			generated-test-sources	maven-archiver		site			surefire-reports

Setting up the environment

Configure Apache

First you have to make sure the following things are not commented out (activated) in the httpd.conf file from the apache webserver:

LoadModule proxy_module libexec/apache2/mod_proxy.so
LoadModule proxy_ajp_module libexec/apache2/mod_proxy_ajp.so
LoadModule vhost_alias_module libexec/apache2/mod_vhost_alias.so
LoadModule rewrite_module libexec/apache2/mod_rewrite.so

If you have a newer version of the web-server (apache), the httpd.conf might not exist. On his place there is a apache2.conf. Just make sure that the modules are present in the mods-enabled/ folder or enable them with a2enmod.

sudo a2enmod proxy
sudo a2enmod proxy_ajp
sudo a2enmod vhost_alias
sudo atenmode rewrite

Still in the same file we have to include the virtual hosts file:

Include /private/etc/apache2/extra/httpd-vhosts.conf

If this file does not exists you can create an empty one on your own.

The next step is to create a directory for the war- and the apache configuration-file. This directory can be anywhere. Also the name of the directory db.freebim.at is not fixed, just make sure to adjust the name in the configuration-files. Additionally you have to make sure that the apache user can read the directory and the files in it.

$ cd <directory>
$ mkdir db.freebim.at
$ cd db.freebim.at
$ mkdir conf
$ touch conf/httpd.conf

Now that we have created the httpd.conf file we can add our apache web-service configuration.

# Web-Application:
<VirtualHost *:80>
   DocumentRoot "<directory>/db.freebim.at"
   ServerName <server-name>
# Proxy specific settings
   ProxyRequests Off
   ProxyPreserveHost On
   ProxyPass / ajp://localhost:8009/
   ProxyPassReverse / ajp://localhost:8009/
    LogLevel debug
   <Directory <directory>/db.freebim.at>
       Options Indexes FollowSymLinks MultiViews
       AllowOverride None
       Order allow,deny
       allow from all
   </Directory>
</VirtualHost>
# Web-Service:
<VirtualHost *:80>
   ServerAdmin <email-address>
   DocumentRoot "<directory>/db.freebim.at"
   ServerName <ws-server-name>
   ProxyRequests Off
   ProxyPreserveHost On
   ProxyPass / http://localhost:8081/
   ProxyPassReverse / http://localhost:8081/
</VirtualHost>

Include the configuration-file it in the httpd-vhosts.conf-file.

Include <directory>/db.freebim.at/conf/httpd.conf

Configure Tomcat

Edit the server.xml-file which is located in the tomcat conf - directory. Enable AJP:

<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

Add a new host:

<Engine ...>
	...
	<Host ...>
	</Host>
	<Host appBase="<directory>/db.freebim.at" autoDeploy="true" name="<server-name>" unpackWARs="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/>
	</Host>
</Engine>

Now that everything is configured you can simply copy the ROOT.war-file in the appBase directory and fire everything up.

$ cp <>/freebim-webapp/target/ROOT.war <directory>/db.freebim.at/

Start the application

Restart Apache-Webserver after you configured it.

$ sudo apachectl restart

Start tomcat. It may be necessary to start tomcat as root when he has not permissions to read or write in the directory that we created before (**/db.freebim.at/).

$ sudo catalina run

Content

A newly created instance of this application will contain

• Two users: admin and guest (as you named them in the freebim.properties - file).
• One Contributor (which is referenced internally)
• One Library Ifc4 with the basic IFC data structure.

For the impatient we provide an anonymized backup of all data stored in our running application at http://db.freebim.at

1. download the backup data from https://github.com/asi-propertyserver/content
2. put the backup into your configured freebim.backup.dir - directory.

/etc/asi-propertyserver/backup
└── 20190330_085328
    ├── nodes
    └── relationships

3. log in as admin
4. press the 'restore backup' button
5. wait and watch the server logs. After restoreBackup has finished you have to reload the app in the browser.

...
2019-03-31 09:12:01,844  INFO SpectroomBackupServiceImpl:241 - restore relationships finished.
2019-03-31 09:12:01,844  INFO SpectroomBackupServiceImpl:243 - restoreBackup finished.
...

Since this is a full backup restore these steps will also override your configured admin and guest user settings.
The login-data used in the backup are:

Username	Password
admin	password

Don't forget to change the password of admin afterwards.
