onto-viewer

onto-viewer is an open-source Java application that provides a number of REST API endpoints to access the content of OWL ontologies. If run together with html-pages frontend, it will visualise them as a web application.

How to run onto-viewer

How to customise your ontology to be properly displayed by onto-viewer

1. We require each ontology IRI to follow the convention described in Vocabularies that use a 'slash namespace', i.e. end with a forward slash character / (e.g., https://www.omg.org/spec/Commons/Classifiers/).
2. We require that all ontologies are "registered" in the meta file(s), which store the relevant metadata, in particular allow for custom modularisation - see https://github.com/edmcouncil/idmp/blob/master/ISO/MetadataISO.rdf for an example of such file.
3. We recommend that all imported ontologies and locally cached and their local references are listed in catalog-v001.xml file.

How to run it locally

To run the onto-viewer locally:

• Download the file named "onto-viewer.zip" from the latest release.
• Unzip the file.
• In the command prompt of your operating system run the following command in the folder with the last release:

java -jar app-v-LAST_VERSION_NUMBER.war

e.g.,

java -jar app-v-0.1.0.war

How to run it using docker

Requirements:

• git (install)
• docker - install:
  • Docker Desktop or ...
  • Docker Engine with Docker Compose plugin

... with FIBO

How to start: Clone the edmcouncil/onto-viewer repository to the onto-viewer directory, go to the onto-viewer directory (run all subsequent commands inside this directory), then build the images (or pull from the registry if available) and run the containers:

# clone the repository
git clone https://github.com/edmcouncil/onto-viewer onto-viewer

# got to the onto-viewer directory
cd onto-viewer

# build images
docker compose build
# alternatively pull images from registry if available
#docker compose pull --ignore-pull-failures

# run the containers
docker compose up -d

After some time, check the status of running containers:

docker compose ps

if they work correctly, the following message will appear:

NAME                        IMAGE                           COMMAND                  SERVICE             CREATED             STATUS                   PORTS

onto-viewer-fibo-viewer-1   edmcouncil/onto-viewer:latest   "sh entrypoint.sh"       fibo-viewer         7 minutes ago       Up 6 minutes (healthy)

The services provide endpoints at the following URLs:

• http://localhost:8080 :- html-pages home page
• http://localhost:8080/fibo :- html-pages general template for FIBO ontology
• http://localhost:8080/fibo/ontology :- onto-viewer for FIBO ontology
• http://localhost:8080/fibo/strapi/admin :- Strapi admin panel for for FIBO ontology (Email: [email protected], Password: devDBonly1)

It is also possible to build (or pull from the registry, if available) Docker images with tag names other than the default develop - use environment variables:

• VIEWER_BRANCH for edmcouncil/onto-viewer, e.g. for edmcouncil/onto-viewer:build-dev:

  echo VIEWER_BRANCH=build-dev >> .env

• HTML_BRANCH for edmcouncil/html-pages, e.g. for edmcouncil/html-pages:build-dev:

  echo HTML_BRANCH=build-dev >> .env

... with an ontology of your choice

It is possible to run containers with any ontology (instead of FIBO):

• place the ontology files of your choice in the onto-viewer-web-app/ontologies subdirectory and the config files in the onto-viewer-web-app/config subdirectory

• using the docker-compose.dev.yaml compose file (instead of the default docker-compose.yaml), build the images,then run the containers:

  echo COMPOSE_FILE=docker-compose.dev.yaml >> .env
  docker compose build
  docker compose up -d

  once all services are up and running, onto-viewer with your ontology will be available at http://localhost:8080/dev/ontology

If you want to see the logs use:

# to view continuous log output for <SERVICE>=dev-viewer
docker compose logs --follow dev-viewer

# to view *100* latest log lines for <SERVICE>=dev-viewer
docker compose logs --tail 100 dev-viewer

Stop the services with the command:

docker compose down

Remove all images and volumes with the command:

docker compose down --rmi all -v
