+# DataSpace
+
+DataSpace is a benchmark for data agents that perform verifiable analytics over
+heterogeneous, task-local workspaces. Each task provides a natural-language
+question and a workspace containing a combination of CSV, JSON, SQLite,
+Markdown, PDF, and video artifacts. The required output is a complete tabular
+result.
+
+DataSpace is also the official benchmark of the
+[KDD Cup 2026 Data Agent Track](https://dataagent.top).
+
+## Release policy
+
+This release makes all 410 task inputs public. It includes `gold.csv` and the
+frozen evaluation configuration for a representative set of 60 tasks, allowing
+end-to-end local development and validation. References for the other 350 tasks
+are withheld for official full-benchmark evaluation.
+
+The public-reference set was selected by deterministic constrained coverage
+optimization over source domains, question--workspace language combinations,
+evidence-carrier combinations, required modalities, analytical operations,
+answer shapes, numeric comparison modes, and ordering behavior. It covers all
+six modalities, all annotated analytical-operation families, and all
+evidence-carrier groups without repeated source samples.
+
+## Benchmark summary
+
+| Property | Value |
+| --- | ---: |
+| Task inputs | 410 |
+| Public reference packages | 60 |
+| Context files | 7,439 |
+| Uncompressed context size | 15.0 GB |
+| CSV files | 2,809 |
+| JSON files | 1,927 |
+| SQLite databases | 402 |
+| Markdown documents | 1,024 |
+| PDF documents | 1,088 |
+| Videos | 189 |
+
+Chinese and English may occur across both the question and workspace artifacts.
+Tasks may require evidence discovery, structured extraction, joins across
+representations, filtering, aggregation, ranking, temporal reasoning, and
+document or video understanding.

+`data/tasks.jsonl` is a lightweight index for the Hugging Face Dataset Viewer.
+It contains questions, workspace paths, available modality composition, file
+inventories, and a public-reference availability flag. It does not expose
+answer or solution-path metadata for withheld tasks.
+
+## Download
+
+Install the Hugging Face Hub client and download the complete release:
+
+```bash
+pip install -U huggingface_hub
+hf download HKUSTDial/DataSpace \
+  release/DataSpace-Benchmark.zip \
+  release/DataSpace-Benchmark.zip.sha256 \
+  --repo-type dataset \
+  --local-dir .
+```
+
+Verify and extract it:
+
+```bash
+cd release
+sha256sum --check DataSpace-Benchmark.zip.sha256
+unzip DataSpace-Benchmark.zip
+```
+
+For task `task_N`, the agent receives:
+
+```text
+DataSpace-Benchmark/input/task_N/task.json
+DataSpace-Benchmark/input/task_N/context/
+```
+
+and should write:
+
+```text
+predictions/task_N/prediction.csv
+```
+
+## Loading the task index
+
+```python
+from datasets import load_dataset
+
+tasks = load_dataset("HKUSTDial/DataSpace", split="test")
+task = tasks[0]
+print(task["question"])
+print(task["workspace_path"])
+```
+
+Resolve `workspace_path` relative to the extracted
+`DataSpace-Benchmark/` directory.
+
+## Evaluation
+
+The official evaluator and baseline implementations are maintained in the
+[DataSpace GitHub repository](https://github.com/BugMaker-Boyan/DataSpace).
+Local evaluation is available for the 60 public-reference tasks. Official
+full-benchmark submissions are scored once over all 410 tasks, and missing
+predictions count as incorrect. Submission and leaderboard instructions will
+be published on the benchmark website.
+
+## Construction and quality control
+
+DataSpace is constructed from EHRSQL and BULL Text-to-SQL source instances.
+The construction pipeline applies cross-language transformation,
+constraint-aware data sampling, modality routing and artifact rendering, and
+human review and data repair. Eleven domain experts cross-reviewed task
+solvability, question clarity, workspace evidence, reference answers, and
+evaluation configurations.
