Jena is one in Java written open source - Framework for semantic networks . It offers a programming interface for loading and saving data in Resource-Description-Framework - Graphs (RDF). Jena is one of the most popular RDF frameworks.
functionality
Jena represents RDF graphs as abstract models in memory or in data sources such as files or databases. These can also be based on Web Ontology Language (OWL). The models can be queried using SPARQL and changed using SPARUL . Jena works internally with various reasoners and can also be operated by external reasoners (such as the Pellet Reasoner).
Jena supports the serialization of RDF graphs according to:
Fuseki
The Jena subproject Fuseki is an RDF Java EE server. The goal of Fuseki is to provide an HTTP interface on RDF data. It supports SPARQL for querying and updating the data. Fuseki can run as a stand-alone server, but comes pre-configured with the Jetty web server .
