Selected research items:
- The ETSI SAREF development framework and open portal;
- The W3C Semantic Sensor Network recommendation;
- The SEAS ontologies: modularized and versioned OWL 2 DL ontologies developed for the ITEA 2 SEAS project: (> 30 modules, > 300 classes, > 300 properties). See for instance:
- The seas:FeatureOfInterest module describes feature of interests and their properties;;
- The seas:EvaluationOntology module describes evaluations of these properties;
- The seas:SystemOntology module describes virtually isolated systems that share connections with other systems;
- The seas:ElectricPowerSystemOntology module instantiates these concepts to describe systems that exchange electricity.
- SPARQL-Generate: an extension of SPARQL 1.1 to generate RDF from an RDF dataset and a set of documents in heterogenous formats. Our current open-source implementation on top of Apache Jena generates RDF from documents in XML, JSON, CSV, HTML, CBOR, plain text, ...
- Lindt: Supporting Arbitrary Custom Datatypes in RDF and SPARQL
- Guidelines for custom datatype publishers;
- Implementation of these guidelines for a custom datatype that describe lengths;
- Extension of the Jena RDF processor and the ARQ SPARQL engine to support the on-the-fly recognition of custom datatypes.
- RDF Presentation and RDF Presentation negotiation:
- An ontology to describe RDF graphs and how they can be validated or presented as documents;
- Some principles for a web where clients and servers can use their preferred format, while letting the other party the possibility to fall back to the RDF world;
- An first implementation of these principles in an extension of Java Jersey;
- A demonstration of this implementation and the principles.
- PhD: Representation of the Meaning-Text Theory Lexical Semantics, and development of the Unit Graphs knowledge representation formalism
