BCI Report's open register has 487 dataset rows and 48 rows for models and papers, each with the furthest of five steps checked; for datasets: listed, read, traced, run, in the matrix. All 293 Hub rows are at step 1 (listed) so far: none of their files has been opened yet.
From a snapshot of the Hub on 19 October:
- 1,922 listings for 28 search terms and 20 tags; 737 are EEGDash mirrors, kept as one row.
- 368 uploads marked as brain-signal data after a classifier pass and a re-check. 146 of them carry no licence tag.
- 28 rows match an existing dataset by metadata. In 27 of them, the stated terms differ from the source's own.
- 15 match corpora that require a signed agreement, a request or a registration; 10 of those can be downloaded from the Hub without a request.
Matches use metadata only: names, sizes, counts. None of the matched uploads' files is downloaded, an uploader may hold permissions the register cannot see, and every row has a correction route, open to uploaders and dataset authors.
