Add bibliographicCitation & Fix broken links
#18
by netzhang - opened
Summary
- Added
bibliographicCitationcolumn toprovenance.parquet, sourced from GBIF occurrence data (2024-05-01 snapshot) - about 5.3M GBIF records (~2.5%) have citation values; non-GBIF records (EOL, BIOSCAN, FathomNet) have null values
- Fixed broken provenance link in dataset card (missing
dataset/prefix in path) - Updated dataset card to document the new column
Details
- Join key:
provenance.source_id = occurrence.gbifID(GBIF rows only) - Citation coverage is limited by what GBIF publishers provide — only ~5% of the full occurrence snapshot has
bibliographicCitationpopulated, and most of those are not Still Image records - File recompressed with ZSTD to match original compression (8.76 GB vs original 8.71 GB)
- Row count unchanged: 213,937,319
