Sherpa
Spark and Sherpa is a Java client API for access to remote SPARQL processors, a style similar to JDBC Java Database Connectivity API, for accessing remote relational databases. SPARQL is a query language for RDF, used to access data in semantic Web applications. Jena and Sesame are paintings of the popular open source Java for working with RDF and SPARQL, however these paintings tend to be both too much and not enough for some common needs. The two frames allow the RDF DataSet model, import and export a variety of formats, plug-in custom storage engine and query with this storage engines patterns.
