GraphQL-LD

GraphQL-LD is a way to query Linked Data using GraphQL.

Instead of querying GraphQL interfaces, Linked Data interfaces are queried, such as SPARQL endpoints, TPF interfaces, Linked Data documents, ... This is done by semantifying GraphQL queries using a JSON-LD context.

Try it out from your browser: http://query.linkeddatafragments.org/

Alternatively, install GraphQL-LD or Comunica SPARQL and execute GraphQL-LD queries on your machine

:myFriends {
  ex:Alice foaf:knows ex:Bob.
  ex:Alice foaf:knows ex:Carol.
}

Remove a single quad

1. Make sure Node.js (>=8.0.0) is installed: https://nodejs.org/en/
2. Install Comunica: npm install -g @comunica/actor-init-sparql
3. Execute the following command:
