FORTH and CNR entered in signing a Service Level Agreement, that grants limited access to CNR in using proprietary software developed by FORTH. More specifically, the agreement defines that CNR is allowed to use the binaries of MatWare software (version 3.0) only for the purposes of operating the Global Record of Stocks and Fisheries VRE powered by the D4Science infrastructure. MatWare is a framework, developed by FORTH, that automates the process of constructing semantic warehouses. It is capable of automatically fetching the contents from the underlying data sources using several access methods (i.e. SPARQL endpoints, HTTP-accessible files, JDBC, etc.), transforming them into RDF descriptions with respect to a top level ontology, ingest them into a semantic warehouse, and evaluate its connectivity by exploiting a connectivity metrics.
