RDFC Pipeline to ingest Hamburg mobility counting data

This repository includes a RDFC Pipeline that converts a provided observation list from the SensorThings API, and converts it into an RDF Linked Data Event Stream using the RDF-Connect framework.

Configure

The configuration of the data published as an LDES is found in docker-compose.yml. Concretely, the parameters are passed as environment variables to the relevant docker container. The pageSize indicates the size of the pages retrieved from the SensorThings API. The URL parameter is the URL of the Observations page that is to be converted to an LDES.


  hamburg:
    ...
    environment:
      - URL=<URL>
      - pageSize=<pageSize>

Setup

To run this, you need to have docker-compose installed

docker-compose up

Consume

To run the client, run

bash client/run.sh

Todo

  • Implement socket solution to keep streaming new members as the underlying stream is updated.
