LINDAS Cube Manager

A web application for cleaning up old cube versions in a LINDAS-compatible RDF triplestore. It identifies cube versions older than the N most recent per base cube, backs them up, and deletes them.

Features

• Interactive deletion wizard (select graph → preview → backup → delete → summary)
• Chunked SPARQL DELETE to handle large cube versions without proxy timeouts
• ZIP backup with selective restore per cube
• Orphan SHACL shape detection and cleanup
• Supports Apache Fuseki, Stardog, and GraphDB

Quick Start

cd web-app
npm install
ENABLE_DESTRUCTIVE_API=true node server.js

Open http://localhost:3001.

Docker

docker-compose up -d

The destructive API is disabled by default. Uncomment ENABLE_DESTRUCTIVE_API=true in docker-compose.yml to enable deletions.

Environment Variables

Variable	Default	Description
PORT	3001	Web server port
ENABLE_DESTRUCTIVE_API	false	Must be true to run deletions
API_AUTH_TOKEN	(none)	Optional bearer token for destructive endpoints

Infrastructure Note

When running against Stardog behind a reverse proxy, set the proxy read timeout to at least 300 seconds for SPARQL UPDATE endpoints. The default 30-second timeout causes failures on large cube versions.
