Linked Data Interactions For Apache NiFi

Apache Nifi is an easy to use, powerful, and reliable system to process and distribute data.

Set up NiFi instance with LDI processors

The processors can be imported into a NiFi docker instance via volume binding:

1. Create a docker-compose.yml file with the following content in a new directory

    services:
      nifi:
        image: apache/nifi:2.0.0
        environment:
          SINGLE_USER_CREDENTIALS_USERNAME: admin
          SINGLE_USER_CREDENTIALS_PASSWORD: ctsBtRBKHRAx69EqUghvvgEvjnaLjFEB
        ports:
          - 8443:8443
        volumes:
          - ./nifi-ext:/opt/nifi/nifi-current/nar_extensions:rw
   

2. Create a directory nifi-ext in your current directory.
3. Download either the ...-nar-bundle.jar and unpack this or download the individual required processors (.nar extension) from the nexus repository. Next, place the required processors in the nifi-ext directory.
4. Finally, start your instance.

    docker compose up
   

5. Log in at https://localhost:8443/nifi with the credentials mentioned in step 1
6. All downloaded extensions are available under the be.vlaanderen.informatievlaanderen.ldes.ldi.nifi group.

All documentation and notes about configuration are available in the NiFi component itself.
