Abstract
MQTT2RDF is a reusable semantic integration framework integrates real-time Knowledge Graph Population with MQTT4SSN, supporting end-to-end semantic analytics. Further, it addresses the description of heterogeneous payload formats and character encodings. The framework provides artifacts for ontology population. MQTT2RDF is build upon the MQTT4SSN ontology, that represents MQTT with its network entities and control packets.
Description
The framework provides the following artifacts that capture live MQTT traffic from the broker, enable RDF instantiation, and subsequently stream the resulting triples to an RDF store:
- MQTT4SSN Ontology
- Node-Red Flows
- RML-based mapping files and scripts
- Jupyter Notebook for semantic analysis
- Docker environment
