There are two ways to get up and running with the Giles Ecosystem: using Docker or installing it directly on your infrastructure. We recommend to use Docker for evaluation and testing purposes, but to install all components directly on your machines in production.

Giles Ecosystem Components

Note

title	Versions

Versioning in the Giles Ecosystem works as follows. Each component has its own version number in the form MAJOR.MINOR.PATCH. Generally, you should always use the latest versions of all components as it is ensured that they will be compatible with each other. Minor version numbers indicate compatibility, which means that Giles v0.5 is ensured to work with Nepomuk v0.5, but might not work with Nepomuk v0.4.5. However, if there is no version v0.5 for Nepomuk, the latest v0.4.X will be compatible.

You might notice that this rule will sometimes lead to odd gaps in version numbers. For example, if Cepheus has only been patched over several releases, but other components had minor or major updates, a major change in a basic part of the system that requires all components to be updated might cause a version jump from v0.1.X to v0.4 in Cepheus, while other components move from v0.3.X to v0.4.

Giles

Giles needs the following software to be installed:

...

Unpack the war file (e.g. by changing its ending to ".zip" and unzipping it)
Find the file WEB-INF/classes/config.properties and edit the following properties:
- giles_files_tmp_dir: This should be an absolute path to the directory where you want Giles to stores its temporary files (files uploaded by users that haven't been processed yet).
- If your Kafka server is not running on the same machine as Giles, or if it is running on a different port than the default port (9092), you have to change the property
  kafka_hosts to reflect this.
- Status
  colour Blue
  title since v0.5
  db.driver: the driver appropriate for you database (e.g. com.mysql.jdbc.Driver for MySQL or org.postgresql.Driver for PostgreSQL, see this page for more drivers).
- Status
  colour Blue
  title since v0.5
  db.url: connection URL for the used database .
- Status
  colour Blue
  title since v0.5
  db.username: username to connect to database.
- Status
  colour Blue
  title since v0.5
  db.password: password to connect to database.
- Status
  colour Blue
  title since v0.5
  hibernate.dialect: the dialect used for your database (see this page for a list of dialects).
- All other properties can later be changed through the webapp itself.
Find the file WEB-INF/classes/user.properties and edit admin password:
- admin=adminPasswordBCrypted,ROLE_ADMIN,enabled: the password is the first value after the equal sign (adminPasswordBCrypted).
Find the file WEB-INF/classes/META-INF/persistence.xml and change it as follows:
- There are three lines that start with <property name="javax.persistence.jdbc.url". In each line, replace /path/to/giles/dbfiles/folder with the path to the folder that should store Giles' DB files. It should look something like this:
  Code Block
  language xml
  <property name="javax.persistence.jdbc.url" value="/path/to/giles/db/folder/users.odb"/>
  Make sure to keep the file name at the end of each line.

Find the file WEB-INF/spring/spring-security.xml and change the following lines:

Code Block

language	xml

<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
	<beans:property name="url" value="jdbc:mysql://localhost:3306/giles" />
	<beans:property name="username" value="" />
	<beans:property name="password" value="" />
</beans:bean>

Change the values of username and password to the username of your DB user and its password. If you did not name the new DB giles, change the url property to reflect the database name (e.g. if you named the database gilesdb, then instead of jdbc:mysql://localhost:3306/giles, put jdbc:mysql://localhost:3306/gilesdb).
If you are using PostgreSQL instead of MySLQ, make sure to replace the driver class name with org.postgresql.Driver.

Now, generate a new war file from the unpacked and changed files and deploy it in your Tomcat.
Info
If you are on a Unix-based operating system, you can do this for example by running the command jar -cvf giles.war . from inside the unpacked Giles folder.
Once deployed, Tomcat should be accessible at http://your.server/giles.

...

Info

title	Upgrading to v0.5

If you are upgrading from an earlier version to version v0.5, you will have to migrate existing data as follows:

Make sure Giles is running without exceptions.
Reregister the other components with Giles (Nepomuk, Cassiopeia, Cepheus) under "Apps".
Go to http://your.giles.server/giles-root/admin/migrate
Enter the username of the user who's data you want to migrate. The username will be a combination of username and provider id. For example for GitHub: githubusername_github. Depending on how much data the user has uploaded, this might take a while.
Once the migration is done for a user, you will see some statistics about how many objects were migrated.

Nepomuk

Nepomuk needs the following software to be installed:

Tomcat 8

You can either build Nepomuk from source by downloading Nepomuk's source code or download the war files uploaded for a release. This page explains how to install Nepomuk using the provided war file. The download page is https://github.com/diging/giles-eco-nepomuk/releases. In most cases, you should choose the latest release.

Once downloaded follow these steps:

Unpack the war file (e.g. by changing its ending to ".zip" and unzipping it)
Find the file WEB-INF/classes/config.properties and edit the following properties:
- app_base_url: The base URL of Nepomuk such as https://your.nepomuk.server/nepomuk.
- If your Kafka server is not running on the same machine as Nepomuk, or if it is running on a different port than the default port (9092), you have to change the property
  kafka_hosts to reflect this.
Find the file WEB-INF/classes/user.properties and edit admin password:
- admin=adminPassword,ROLE_ADMIN,enabled: the password is the first value after the equal sign (adminPassword).

Find the file WEB-INF/spring/root-contextx.xml and change the property baseDirectory of following bean definitions:

Code Block

language	xml

<bean id="imageStorageManager"
	class="edu.asu.diging.gilesecosystem.nepomuk.core.files.impl.FileStorageManager">
	<property name="baseDirectory" value="/path/to/image/parent/folder/" />
	<property name="fileTypeFolder" value="images"></property>
</bean>

<bean id="pdfStorageManager"
	class="edu.asu.diging.gilesecosystem.nepomuk.core.files.impl.FileStorageManager">
	<property name="baseDirectory" value="/path/to/files/parent/folder/" />
	<property name="fileTypeFolder" value="pdfs"></property>
</bean>

<bean id="textStorageManager"
	class="edu.asu.diging.gilesecosystem.nepomuk.core.files.impl.FileStorageManager">
	<property name="baseDirectory" value="/path/to/files/parent/folder/" />
	<property name="fileTypeFolder" value="texts"></property>
</bean>

<bean id="otherStorageManager"
	class="edu.asu.diging.gilesecosystem.nepomuk.core.files.impl.FileStorageManager">
	<property name="baseDirectory" value="/path/to/files/parent/folder/" />
	<property name="fileTypeFolder" value="others"></property>
</bean>

Each base directory needs to point to a folder to store images, pdfs, texts, or other files.

Now, generate a new war file from the unpacked and changed files and deploy it in your Tomcat.
Info
If you are on a Unix-based operating system, you can do this for example by running the command jar -cvf nepomuk.war . from inside the unpacked Nepomuk folder.
Once deployed, Tomcat should be accessible at http://your.server/nepomuk.

Cepheus

Cepheus needs the following software to be installed:

Tomcat 8

You can either build Cepheus from source by downloading Cepheus' source code or download the war files uploaded for a release. This page explains how to install Cepheus using the provided war file. The download page is https://github.com/diging/giles-eco-cepheus/releases. In most cases, you should choose the latest release.

Once downloaded follow these steps:

Unpack the war file (e.g. by changing its ending to ".zip" and unzipping it)
Find the file WEB-INF/classes/config.properties and edit the following properties:
- cepheus_url: The base URL of Cepheus such as https://your.cepheus.server/cepheus.
- If your Kafka server is not running on the same machine as Cepheus, or if it is running on a different port than the default port (9092), you have to change the property
  kafka_hosts to reflect this.
- If you want Cepheus to

...

- create a different image format than tiffs, use a different dpi value, or a different type of image than RGB, you can change those settings in this file as well.
Find the file WEB-INF/classes/user.properties and edit admin password:
- admin=AdminPassword,ROLE_ADMIN,enabled: the password is the first value after the equal sign (AdminPassword).

Find the file WEB-INF/spring/root-contextx.xml and change the property baseDirectory of following bean definitions:

Code Block

language	xml

<bean id="fileStorageManager" class="edu.asu.diging.gilesecosystem.util.files.impl.FileStorageManager">
	<property name="baseDirectory" value="/path/to/cepheus/folder/" />
	<property name="fileTypeFolder" value="tmp"></property>
</bean>

The base directory property needs to point to a folder where Cepheus will store temporary files.

Now, generate a new war file from the unpacked and changed files and deploy it in your Tomcat.
Info
If you are on a Unix-based operating system, you can do this for example by running the command jar -cvf cepheus.war . from inside the unpacked Cepheus folder.
Once deployed, Tomcat should be accessible at http://your.server/cepheus.
