Introducing RDQLPlus

RDQLPlus is a tool for querying RDF graphs, featuring graphical results in a zoomable user interface (ZUI). It can work with existing RDF files,Jena2 RDF databases, and a native-Java database called Mckoi (included).

RDQLPlus does its job by interpreting commands written in a simple command language, called RIDIQL. Here are a few of the things you can do with the RIDIQL command set:

• INSERT and DELETE statements into/from RDF graphs ("Models")
• CREATE and DROP entire models in RDF storage locations ("Stores")
• DUMP and LOAD models in RDF/XML, N-TRIPLES, and N3 format
• Copy RDF graphs (or sub-graphs) from one model to another
• Query and work with inference models (using one of Jena's reasoners) given an ontology and an instance model
• Output query results in text form
