PRISSMA is an open source Java/Android RDF rendering engine that selects the most appropriate presentation of RDF triples according to mobile context. PRISSMA is compatible with the Fresnel vocabulary and is based on a graph edit distance algorithm that finds optimal error-tolerant subgraph isomorphisms between RDF context graphs.
Shi3ld is an open source access control module for enforcing authorization on triple stores. Shi3ld protects SPARQL queries and HTTP operations on Linked Data and relies on attribute-based access policies.
A dataset containing malicious triples that could be used to evaluate the resilience of Linked Data applications or to train spam filters.
The work dissects this issue into three research questions: how to declaratively describe context by complying with Linked Data best practices, how to enable context-aware adaptation for Linked Data consumption, and how to protect access to RDF stores from context-aware devices.The PhD Thesis has been co-supervised by Fabien Gandon and Ivan Herman.
