BODC LDES Demo documentation

This repository contains the documentation for the BODC LDES Demo.

Requirements and technologies used

The python script used in this project requires Python 3.X. To install the required dependencies, run the following command:

pip install -r requirements.txt

Usage

To run the script, run the following command:

python BODC_LDES_Demo.py

Diagram of BODC LDES Demo

The python file can be broken down into the following components:

• Input :

  • ./pykg2tbl/SPARQL_query_with_parameters.SPARQL: SPARQL file with parameters to be filled in by ./pykg2tbl/params.json
  • ./pykg2tbl/params.json: Parameters to be filled in ./pykg2tbl/SPARQL_query_with_parameters.SPARQL
  • ./pysubyt/LDES_fragment_template.ttl: ttl file that will be populated by the output of the SPARQL query

• pykg2tbl

  • getTriples():
    • Runs the SPARQL query with the parameters in ./pykg2tbl/params.json
    • Returns the output of the SPARQL query as a list of triples

• pysubyt

  • makeLDESFragments():
    • Takes the list of triples from pykg2tbl.getTriples() and populates the ./pysubyt/LDES_fragment_template.ttl file
    • Returns the populated ./pysubyt/LDES_fragment_template.ttl file

• Output

  • LDES_fragments.ttl:
    • The output of the script, a populated ./pysubyt/LDES_fragment_template.ttl file
