Notes

Figshare marks the deposited index files CC BY 4.0. The record exposes URLs and WeChat article identifiers rather than redistributing image files, so original content permissions still need separate review.

Access preflight and acquisition

CLI

# Read-only preflight
eyehub download ophthalwechat --data-dir ./data --dry-run --json

# Explicit transfer, only when preflight reports supported behavior
eyehub download ophthalwechat --data-dir ./data

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('ophthalwechat')
print(preflight_dataset(ds, './data'))  # no transfer
