Libraries and Tools

Software libraries, tools, and integrations for working with CAC Ontology.

Python Tools

The CAC Ontology repository includes Python tools for working with the ontology:

Installation

git clone https://github.com/Project-VIC-International/CAC-Ontology.git
cd CAC-Ontology
pip install -r requirements.txt

Usage

Python tools are available in the repository for:

• Ontology validation
• File processing
• Data transformation
• Analysis and querying

Docker Tools

Validation Infrastructure

Docker-based validation using SHACL:

docker compose -f testing/docker-compose.yaml up -d

This sets up validation infrastructure that automatically validates all ontology files.

SPARQL Tools

Query Examples

Example SPARQL queries are available in the example_SPARQL_queries/ directory:

• Common investigation patterns
• Analytics queries
• Data extraction queries
• Relationship mapping queries

SPARQL Endpoints

SPARQL endpoints can be set up using standard RDF triple stores that support SPARQL queries.

RDF Libraries

CAC Ontology files are standard RDF/OWL, compatible with:

Python

• rdflib - Python library for working with RDF
• owlready2 - OWL ontology manipulation in Python

Java

• Apache Jena - Java framework for building Semantic Web applications
• OWL API - Java API for working with OWL ontologies

JavaScript/TypeScript

• rdf-ext - RDF/JS interface implementation
• N3.js - Lightning fast, asynchronous, streaming Turtle/N3 RDF library

.NET

• dotNetRDF - .NET library for working with RDF data

Validation Tools

SHACL Validation

CAC Ontology includes comprehensive SHACL validation:

• Validation shapes for all major modules
• Business rule enforcement
• Data quality checks

RDF Validators

Standard RDF validators can be used:

• W3C RDF Validator
• Apache Jena validation tools
• Custom validation using SHACL processors

Integration Libraries
