Dutch key registers — property ownership, persons, commercial registries — can be linked to increase their value. But not all data is public, and managing access in a linked data context is non-trivial: SPARQL’s free querying makes it hard to enforce fine-grained access rights.
This paper, presented at the International Conference on Formal Ontology in Information Systems (FOIS 2024), describes an experiment where authorisation rules are modelled in an ontology, and a demonstrator that rewrites SPARQL queries at runtime so that access rights are enforced automatically.
