RODI Relational-to-Ontology Mapping Quality Benchmark

RODI Relational-to-Ontology Mapping Quality Benchmark

RODI is a benchmark suite for testing the quality of (semi-)automatically generated, RDB2RDF (relational database to RDF) mappings.

When referring to this work, please always cite our most recent publication (currently [1]). For an overview of the first prototype, please see [2].

Requirements

RODI is implemented in Java and requires JRE 1.8 or later.

For developers, to compile and run the workspace, a corresponding JDK is needed. Eclipse is recommended for development and an Eclipse project is pre-configured. RODI also relies on a number of publicly available JAR libraries that are not included with in the repository (see below).

Download and Installation

For use by non-developers, there is a complete pre-packaged distribution of the latest RODI release available from the University of Oxford. It runs directly from the command line.

Development requires a clone of this git repository. You may either use the pre-configured Eclipse project, in which case several external libraries need to be added manually. Please refer to manual.pdf for a full list of required libraries including download instructions. As an alternative, you may use the included Maven to automatically download dependencies. To generate a RODI JAR file from the command line using Maven, run: mvn package

Usage

RODI can be run as an Eclipse project, or from the command line using the latest release. When starting from Eclipse (or from a Maven-generated JAR), the Main type to execute is com.fluidops.rdb2rdfbench.Main. Try --help for command line options.

For further usage documentation, please refer to the user's manual (manual.pdf) included with the release distribution.

Experiments with Karma tool

Dear All,

I would like to test the Karma tool that, according the last version of the RODI paper, is included among the benchmark experiments.

Is there a bash script available to test Karma in RODI?

Thank you.

Failed to create Sesame repository

Hi,

I updated the maven dependency for slf4j-log4j12 to this updated version since it was giving an error regarding the 1.7.4 version:

org.slf4j slf4j-log4j12 1.7.21

After running the main.java I received this error:
