Port Marmotta to Eclipse RDF4J

Apache Marmotta has become one of the most prominent projects within the open source community of Linked Data. It brings together the standards of the Semantic Web (RDF, SPARQL) and a set of new and innovative technologies of Linked Data such as: LDP, LDCache, LDPath, etc. Currently Apache Marmotta relies on the Sesame Framework for handling data as RDF internally within its modules. However, Sesame is undergoing a deprecation process and it’s being replaced by its successor Eclipse RDF4J. In order to keep Apache Marmotta updated and insurance its compatibility with new developments, it is a fundamental need to port Apache Marmotta to the new version of this Framework.
