  "introducing_source": "wiki/sources/u-cast-2025.md",
  "dataset_type": "high-dimensional multivariate time-series forecasting benchmark suite",
  "temporal_structure": "regularly sampled numeric multivariate time series with aligned channels inside each dataset; frequencies range from milliseconds to days",
  "actions_or_interventions": "none; passive forecasting benchmark without controllable action or intervention channels",
  "suitability_note": "anchor benchmark for HDTSF; strongest when the question is channel count, cross-channel dependency, latent hierarchy, and scalability rather than action-conditioned operations modeling",
  "license_note": "Hugging Face dataset page lists Apache-2.0; dataset-card provenance fields are sparse and should be checked against the paper and source datasets before operational use",
