RML2SHACL

A tool to generate SHACL shapes from RML mapping files for RDF graphs validation.

Prerequisite

Install the required dependencies:

pip install -r requirements.txt

Usage

General usage info:

usage: main.py [-h] [-logLevel LOGLEVEL] MAPPING_FILE

positional arguments:
  MAPPING_FILE          RML mapping file to be converted into SHACL shapes.

optional arguments:
  -h, --help            show this help message and exit
  -logLevel LOGLEVEL, -l LOGLEVEL
                        Logging level of this script
                        Possible values: INFO,DEBUG,WARN
  -o ONTOLOGY_DIR       Directory/path with additional ontology files to be converted 
                        into SHACL shapes.
  -o SCHEMA_DIR         Directory/path with schemas to be converted into SHACL shapes.
                        Currently supports: XSD
  

To generate your shacl shapes:

python3 main.py MAPPING_FILE

An example with an additional folder containing ontology-files as well as a folder containing schemas:

python3 main.py -o ONTOLOGIES_PATH -s SCHEMA_PATH MAPPING_FILE

For more clarity to locate the generated shape file, please delete the shapes/ directory that came with this repo first. Otherwise, the generated shape file will have the same parent paths as the mapping file but under the shapes/.

Eg:

If you execute the following:

python3 main.py evaluation/astrea_test/ssn/mapping.ttl

The generated shape file will then be located here: shapes/evaluation/astrea_test/ssn/mapping.ttl-output-shape.ttl
