SkoHub Reconcile

This repository provides a Reconciliation Service for the the SkoHub core infrastructure.

The module is designed to serve SKOS Vocabularies according to the Reconciliation API specification. It currently supports:

To insert vocabularies to the service, you can use the SkoHub Reconcile Publish module.

The service currently suppports the following reconciliation services of the above mentioned specifications:

Be aware that this is still in proof-of-concept phase.

Additional Endpoints

  • /ping to check if the service is up
  • /vocabs to see all vocabularies and their service manifest urls

Setup

This service uses docker and docker compose to run. To run it, you need to have docker and docker compose installed. Please see the docker installation guide.

Environment Variables

To run the service, you need to have a .env file in the root directory of the project. You can use the provided .sample.env as a template. Run cp .sample.env .env to create the environment file.

Network

The service uses an external network to communicate with the SkoHub Reconcile Publish module, which is used to publish vocabularies to the service.

Before you start the service make sure the network reconcile-backend exists. You can create it with:

docker network create reconcile-backend

Elasticsearch Data Directory

Create the data directory for elasticsearch with mkdir -p data/elasticsearch/data

Run the Service

Then, you can run the service with:

docker compose up

This will start the Reconciliation service on the port specified with APP_PORT_EXPOSED in .env. Add -d to run the service in the background. Note that the Elasticsearch and Kibana services will also be exposed.

If you start the service for the first time an index with the appropriate mapping will be created automatically. If you want to reset the index later, you can use the following command:

docker compose run --rm reconcile npm run reset-index

Development

For development you can start the service with docker compose -f docker-compose.dev.yml. This will mount the ./src-folder into the container and the reconcile service will be started with npm run dev. Nodemon will then listen to file changes in the mounted folder and whenever you change something restart the service.

Credits

The project to add a Reconciliation Service to SkoHub has been initiated by Andreas Wagner and carried out in cooperation with the SkoHub.io team.
