ODS-YARRRML-Toolkit

A Python3 implementation of YARRRML Mapper and SPARQL Querying for OpenDataSoft-API data.

Installation

First, clone the repository:

git clone https://github.com/benjimor/ods-yarrrml-toolkit.git

Then, assuming you already have Python3 and Pip installed, install the dependencies:

Running in a virtual environment is recommended

pip3 install -r requirements.txt

Run It

Transform an ODS API result (JSON) into RDF

Transform an ODS json api result file into an RDF (ttl) file using a YARRRML Mapping with the following command:

python3 YARRRMLMapper.py <source> <destination> <mapping>

example:

Files are in root directory of this project

python3 YARRRMLMapper.py example/rap_world_data.json example/rdf_result_data.ttl example/rap_world_mapping.yml

Query the resulting file using with SPARQL

Query the resulting ttl file with a SPARQL query using the following command:

python3 SPARQL.py <source> <query>

example:

Files are in root directory of this project

python3 SPARQL.py example/rdf_result_data.ttl example/query.sparql
