OPAL Web-Service
This component is part of the demo project. It requires opaldata to access data. It provides data for the web-ui.
How to run
To be able to run you must provide a .env file in the root folder of the project that is similar to
# Elasticsearch configuration
OPAL_ELASTICSEARCH_URL=localhost
OPAL_ELASTICSEARCH_PORT=9200
ES_INDEX=opal
# SPARQL endpoint for previously crawled dataset
SPARQL_ENDPOINT_PREVIOUS=http://localhost:3030/2020-06/
# SPARQL endpoint for latest crawled dataset
SPARQL_ENDPOINT_LATEST=http://localhost:3030/2020-10/
# Will be added as parameter 'urlPrefix' in GEO_REDIRECT URL
GEO_URL_PREFIX=http://localhost:3000/view/datasetView?uri=
# URL to redirect to when map bounding box was selected by user
GEO_REDIRECT=http://localhost:8081/getGeoDatasetsHtml
Then, by running the command
docker-compose up -d
you have the demo containers running and the demo is available on port 8081 (you can set any port that you want in the docker-compose.yml) of your server.
Check the running Docker container by opening http://localhost:8081/opalinfo
