Attention: This repo is outdated. The tools in this repo were written for RDF* before Apache Jena included support for RDF* and now for RDF-star. The conversion as implemented by the tools in this repo is not in line with the semantics of RDF-star as defined in the RDF-star spec. Unfortunately, we currently don't have the resources to update and to maintain these tools anymore. For an RDF programming framework for Java that has up-to-date support for RDF-star consider Apache Jena or Eclipse RDF4J.

This package provides a collection of command line tools and Java libraries to process RDF* data and SPARQL* queries.

New to RDF* and SPARQL*? If you want to know what RDF* and SPARQL* are about, please refer to our short position statement: "The RDF* and SPARQL* Approach to Annotate Statements in RDF and to Reconcile RDF and Property Graphs."

The command line tools available in this collection are:

• a tool to convert RDF data into RDF* data,
• a tool to convert RDF* data into RDF data,
• a tool to rewrite SPARQL* queries into SPARQL queries,
• a tool to execute SPARQL* queries over RDF* data, and
• a tool to execute SPARQL* queries over RDF reification data in a SPARQL endpoint.

The core components of the Java source code of the aforementioned tools are RDF*/SPARQL*-aware extensions for the Apache Jena framework for building RDF-based applications. Hence, the source code in this repository may also be used as a Java library for building RDF*-based and/or SPARQL*-based applications. In particular, the source code contains the following components:

• a parser for the Turtle* format,
• a simple Turtle*-like serializer, and
• a parser for SPARQL* queries.

For a collection of command line tools and Java libraries that connect the RDF* data model and Property Graphs refer to our RDFstarPGConnectionTools.

Have Docker installed then at a bash command prompt run:

docker run --rm -it -v RDFstarTools_m2:/root/.m2 -v `pwd`:/mnt maven:3.8-jdk-8 /mnt/entry.sh
