It is not intended as row-wise tabular training input.57 58Load `schema.nt` and the files under `csharp/` into an RDF-capable store.

Clone Stack2Graph and configure `.env` with service paths and an HF token.832. Start local services:84 85```bash86docker compose up -d87```88 893. Download and prepare the knowledge graph service state:90 91```bash92python -m experiment.sources.hf93```94 95## Quality Notes96 97- Vote information is represented as aggregates, not raw individual vote events.98- Not all moderation context or full revision history is represented.99- Community-generated Stack Overflow content may contain errors, outdated information, bias, or temporal drift.100 101## License And Attribution102 103This dataset is derived from Stack Overflow content and is distributed under `CC-BY-SA-4.0`.104Preserve required attribution and license notices when redistributing derived artifacts.105 106## Citation107 108If you use this dataset, cite the Stack2Graph project and preserve Stack Overflow attribution requirements:109 110- Kleybolte, L.
