Updating the federation

• Before running the API, you should update the docker-compose.yml file to reflect the available sources and their corresponding endpoint
• By convention, the endpoints of sources specified in the SOURCES environment variable are upper-cased, e.g. the endpoint of DBpedia is specified with the environment variable ENDPOINT_DBPEDIA

Important directories

• The API source is located at ./api/pipe
• The client source is located at ./client/src

Todos

• Include engine dependency compilation as part of the API Dockerfile
• Add a lock to ensure only one query is executed at once
