MOBIUSI INCThis dataset focuses on paintings' historical owners, collecting institutions, transfer events, and related documentary records. It contains questions that require linking multiple provenance nodes and dates, along with answers, provenance chains, reasoning steps, and evidence links. The text-based data supports training and evaluating provenance tracing and evidence-based reasoning in painting heritage research, without requiring image input.

| question_text | string | Question to answer by tracing the painting's provenance across multiple source nodes and points in time. |
| evidence_links | array | Specific documentary evidence supporting the answer and inferences made along the provenance chain. |
| reasoning_steps | array | Ordered explanation showing how the answer follows from linking provenance nodes, dates, and source evidence. |
