Lemon-KG: Research-centered ontology and SHACL

• ontology: OWL/Turtle modules (core, diversity, energy, context, align)
• shapes: SHACL shapes for validation
• data: Example instances (hypotheses)
• queries: SPARQL queries for analysis
• mappings: Per-project mappings to Lemon-KG
• tools: Python tooling (rdflib, pyshacl, loaders, metrics)
• graphdb: Helper scripts and notes for GraphDB

Quick start

1. Assemble all ontology and data into build/lemon-kg.ttl
   • python3 tools/assemble.py
2. Validate with SHACL
   • python3 tools/validate.py
3. Load to GraphDB (env GRAPHDB_URL, REPO_ID)
   • ./graphdb/load.sh build/lemon-kg.ttl

Using bundled cc-sdd (local, no upstream changes)

Prereqs: Node 18+

# Run the vendored CLI in this repo only
./tools/vendor/cc-sdd/dist/cli.js \
  --agent cursor \
  --profile minimal \
  --yes \
  --overwrite skip \
  --backup="/tmp/cc-sdd-backup"

Outputs here (safe):

• .cursor/commands/kiro/*
• .kiro/settings/*
• AGENTS.md

Update the vendor snapshot later (optional):

# Refresh from your local cc-sdd clone (keeps upstream untouched)
rsync -a /Volumes/lemon/cursor/cc-sdd/tools/cc-sdd/dist/ tools/vendor/cc-sdd/dist/
rsync -a /Volumes/lemon/cursor/cc-sdd/tools/cc-sdd/templates/ tools/vendor/cc-sdd/templates/

Guardrails:

• Do not modify upstream cc-sdd here.
• Commit the vendored tree if you refresh it, so CI is reproducible.
