Ontology Coverage Dashboard

SvelteKit application for comparing an instantiated ontology against an originating ontology with a project-managed competency-query set executed server-side with Comunica.

Stack

• SvelteKit + TypeScript
• Flowbite-Svelte + Tailwind CSS
• @comunica/query-sparql
• Vitest + Playwright

Setup - Docker

This repository includes two Docker Compose files:

• compose.yaml: standard/runtime setup
• dev-compose.yaml: development-oriented setup

Before running either setup, configure your environment file:

cp env .env

Then edit .env and set values for your environment.

• SPARQL_ENDPOINT_URL (required): URL to the SPARQL endpoint (e.g. http://ontop:8080/sparql) or empty for examples
• PORT (optional): port to expose the dashboard on (default: 3000)

Example commands:

# Run the default setup
docker compose -f compose.yaml up

# Run the development setup
docker compose -f dev-compose.yaml up --build

Environment

• SPARQL_ENDPOINT_URL (optional): absolute URL to the SPARQL endpoint that should be queried by Comunica (for example http://ontop:8080/sparql)
• If SPARQL_ENDPOINT_URL is not set, analysis falls back to the selected bundled example ontology.
• Analysis requests now use JSON rather than form submissions, so Docker deployments do not need a build-time trusted-origins setting for SvelteKit CSRF protection.

What it does

• Uses a bundled AIdoc-AP originating ontology together with a configured SPARQL endpoint source
• Runs server-side coverage analysis against bundled competency queries
• Shows a traffic-light summary with counts and coverage percentage
• Supports filtering and per-query detail inspection
• Returns actionable validation and query-set error feedback
