The installation of the ORR is greatly facilitated with the use of Docker container technology. Your target machine should have the following:

The Docker images comprising the ORR system are:

Image Name Purpose
mmisw/orr ORR The ORR system itself
mongo MongoDB Persist all data
franzinc/agraph AllegroGraph Triple store and SPARQL endpoint

Note: You don't need to manually download these images. With the docker-compose.yml file described below, Docker Compose takes care of pulling and running these images.

Configuring and Launching the ORR System

To further facilitate this task, we have put together a template that you can get from Expand the zip or tarball under a location of your choice.

If you have a Git client, you can alternatively clone the orr-instance-template repository; see README file there for details.

The template mainly consists of configuration files and the docker-compose.yml specification to be passed to Docker Compose. The template contents are:

├── config
│   ├── notifyemails
│   └── orront.conf
├── docker-compose.yml

From the template, edit the following files (please see the contents of the files for additional details):

  • to indicate a number of required settings via environment variables;
  • config/orront.conf, the master configuration for your ORR instance;
  • config/notifyemails, to specify email addresses that should be notified whenever there is a registration event (user, organization, or ontology). This is optional.

With these pieces in place, you can now launch the ORR:

$ source
$ docker-compose up -d
Starting agraph
Starting mongo
Starting orr

To inspect the ORR log:

$ docker logs -f --tail=100 orr

Open the ORR in your browser. For example, with 9090 as the associated host port (value of ORR_HOST_PORT in, you can now open http://localhost:9090/ont/. You can login with the username "admin" and the password indicated via the admin.password entry in orront.conf.

To stop and restart individual containers:

$ docker stop orr
$ docker start orr
$ docker restart orr

To shutdown the whole ORR:

$ docker-compose down
Stopping orr ... done
Stopping mongo ... done
Stopping agraph ... done
Removing orr ... done
Removing mongo ... done
Removing agraph ... done

A crontab like the following could be defined for a complete ORR start at reboot time:

@reboot sleep 30 && docker start mongo agraph orr


The above Docker set-up should in general be complemented with appropriate mechanisms toward a production environment. Aspects to consider include: making your ORR instance externally visible, re-starting the containers to reflect configuration and image updates, logging, backups, etc. Also, depending on the target platform, the user performing the deployment should have the relevant Docker privileges. For example, via a command like: sudo usermod -a -G docker username. Please check with your sysadmin.

Apache HTTPD proxy configuration

Just as a suggestion (please check with your sysadmin), the following is a possible Apache proxy configuration to externally expose the ORR itself and the SPARQL endpoint through the /ont and /sparql context paths under your main HTTP server:

ProxyPass        /ont http://localhost:9090/ont
ProxyPassReverse /ont http://localhost:9090/ont

ProxyPass        /sparql http://localhost:10035/repositories/mmiorr
ProxyPassReverse /sparql http://localhost:10035/repositories/mmiorr
