Frequently asked questions

Clarify preview scope, scale and permissions before delivery.

Does the kit contain the full dataset?

Field references and README; no original data records. The public kit is for preview evaluation. Full data requires a confirmed version and delivery list.

Why does catalog scale differ from preview count?

Catalog scale comes from registered sources or official specifications. Public kits contain limited excerpts or references. Verify actual deliverable scale for your selected scope.

Can I use it for training or commercial projects?

Confirm the selected version’s license, provenance and permitted uses. Catalog listing and preview access do not grant training, commercial-use or redistribution rights to the full data.

Evaluation and acceptance checks

Check the actual samples before selecting a batch. These are suggested acceptance criteria, not quality guarantees for the full corpus.
