RML-Validator

Validator for [R2]RML mapping documents.

It is implemented in Java based on RDFUnit test cases applied to mappings defined with RML.

Clone

You can clone the RML- Validator (and its subprojects)

git clone https://github.com/RMLio/RML-Validator.git

Installation

You can install RML-Validator using Maven, so make sure you have installed it first: http://maven.apache.org/download.cgi and java 1.7

bin/RML-Validator

Usage

The RML-Validator can be run using Maven. You can run a validation process by executing the following command.

mvn exec:java -Dexec.args=-m "<mapping_file> [-mqa -dqa -mdqa]"

Or using the JAR file

java -jar RMLValidator-1.0.jar -m "<mapping_file> [-mqa -dqa -mdqa]"

With

<mapping_file> = The RML mapping file conform with the [RML specification](http://semweb.mmlab.be/ns/rml)
-mqa = Triggers the Mapping Quality Assessment (the RML mapping document conform with skolemized and inferred statements).
-dqa = Triggers the RDF Dataset Quality Assessment.
-mdqa = Triggers both the Mapping and the RDF Dataset Quality Assessment.
add -V to validate it using RDFUnit	

Remark

On OSX, it might be needed to export JAVA_HOME=$(/usr/libexec/java_home)
