Initial Configuration

These settings will configure your installation for your environment.

Triple-store Configuration

Your OntoPortal Virtual Appliance can run with multiple RDF triple-stores as backend storage.

Starting with version 4.0, the virtual appliance ships with AllegroGraph as the default RDF store. To fully configure it, visit the AllegroGraph Configuration page before you begin uploading content.

If you want to switch to using 4store instead (not recommended), visit the 4store Configuration page for detailed instructions.

OntoPortal can also run with Virtuoso; see the Virtuoso Configuration page. It can also run with GraphDB, which is not yet documented here — see agroportal/project-management#229 for the current status and pointers.

If you use the Virtual Appliance 4.0 based on the AgroPortal codebase, it ships with Virtuoso as the default triple-store.

Adding ontologies

The detailed ontology submission process is described in the Submitting Ontologies section.

To start, since you don’t have any non-administration accounts, you can add an ontology using the OntoPortal Admin User at http://{ip_address_of_appliance}/ontologies/new.

Enabling emails

To let the system send emails for lost passwords, notes, and ontology processing reports, you need to provide a valid mail server (smtp) configuration. The configuration should be provided in the /srv/ontoportal/ontologies_api/current/config/environments/appliance.rb file.

Here are the available settings:

 config.enable_notifications   = true # Set to 'true' to send emails
 config.email_sender           = "admin@example.org" # Default sender for emails
 config.email_disable_override = true # If this is set to 'false', all emails will be sent to the email configured in the 'email_override' setting
 config.email_override         = "admin@example.org"
 config.smtp_host              = "smtp.example.org"
 config.smtp_port              = 25
 config.smtp_auth_type         = :none # :none, :plain, :login, :cram_md5
 config.smtp_user              = "username" # only used if auth_type is not :none
 config.smtp_password          = "password" # only used if auth_type is not :none
 config.smtp_domain            = "example.org"

Once you have changed your settings, you will need to restart the server by running the command

sudo opctl restart

or, if you run a VA before v4.0

/sbin/service unicorn restart
