SAFERWATER tackles critical challenges in water management, including climate change, population growth, and rising cyber threats to essential infrastructure. The project aims to modernize dams and water supply systems by leveraging digitalization to boost security, resilience, and operational efficiency.
Our team’s contribution focuses on deploying PADME, our decentralized analytics platform. PADME enables secure, sovereignty-preserving model training across diverse data sources in the water sector. To streamline this process, we integrate heterogeneous data as Virtual Knowledge Graphs (VKGs), reducing complexity for decentralized analytics and simplifying data querying. VKGs allow non-RDF data sources (e.g., SQL databases) to be accessed via SPARQL, the standard query language for linked data.
We are developing a novel tool to support stakeholders throughout the data access and allocation lifecycle. This tool will:
- Simplify provisioning and maintenance of VKG engines (e.g., Ontop), ensuring seamless SPARQL-based access to non-RDF data.
- Enhance data governance through access logging and policy enforcement, aligning with regulatory and organizational requirements
- Experience in software development with Java
- Experience with Docker
- Basic experience in frontend development
- Ideally: Experience in the Java RDF-Stack (e.g. rdf4j)
