Data validation

This repository contains the data validation module for the TEC Toolkit.

Getting Started

These instructions explain how to run and customise the Data Validation module.

Prerequisites

• RDFox (> v.6) ¹

In the following, we assume that it is installed and added to the PATH.

Running (RDFox)

The main entry point is the master script.

This data validation module reads the RDF files and checks if some constraints are verified.

How to execute it:

RDFox sandbox <root> master

where <root> is the "scripts" folder (. if you are inside it).

Functionalities

Check if the data are "valid"

1. Run the data validation module
2. Check that all queries have 0 answers

Add another validation check

1. Add a file "check-CUSTOM_NAME-rules" with the rules to check
2. Add a file "check-CUSTOM_NAME-queries" with the ASK queries
   • Note that the queries must return no answer if the check is passed
3. Add a new command exec check CUSTOM_NAME in the "validate" file
