SPARQL-RML Rewriter

Given a set of RML mappings which maps RDF data (source) to RDF data (target), and given a SPARQL query formulated in terms of the target RDF data, rewrite the SPARQL query to a SPARQL query formulated in terms of the source RDF data.

Usage

Docker

Create a Docker image and run it based on the provided Dockerfile.

Compiling

Build with Maven:

mvn clean package.

The result is a CLI program. Run the program to get the help information:

java -Djava.library.path=<path-to-jpl7-library> -jar <srr-filename>

Where <path-to-jpl7-library> is the folder containing libjpl.dylib libswipl.dylib. This is to be found in the swipl installation directory.

Dependencies

This software uses four libraries: + Apache Jena ARQ for SPARQL manipulation + JPL7 to interface with SWI-Prolog + JGraphT for some graph analysis used in the rewriting + PicoCLI for the Command Line Interface (embedded source code)

Limitations

RML mappings may only use specific templates for termmaps. The templates must: + contain only one variable + the variable must occur at the end of the template

Future

  • Add support for general templates
  • Replace prolog unification with Clojure.core.logic unification
