  • Research on the topic of heterogeneous data integration using semantics, under the title “S3-AI approach for Premarpol (marine-weather) Open Data”, can be obtained from here.
  • Experimental 3-years data (in .csv) from marine (underwater) and weather sensors, can be obtained from here.
  • Experimental queries (using D2R Server, Apache Fuseki server and SPARQL endpoints):
    Unified view of 2 SPARQL endpoints mapped to a shared ontology. Two experimental sites (different local RDBs of marine-weather applications) are virtualized (RDF graphs) by 2 different SPARQL endpoints, named Samos_station (data from sensors in Samos port) and Karlovasi_station (data from sensors in Karlovasi port) respectively (try browsing and querying those by clicking on those names).
