@shandongfx @arw36 keep an "Opportunistic Database of Biodiversity Databases" (ODBD) https://docs.google.com/spreadsheets/d/1qsK1MNLsi-QjK9VptgeV2HfrB7mWUVxjZdaj_P9Qs-Y/edit#gid=975168115 I suspect that some of these might overlap with trait datasets registered with the open trait network https://opentraits.org/datasets . Suggest to explore ways to link into ODBD from opentraits.org .
