docs(data): evaluate richer taste sources (FartDB, PlantMolecularTasteDB) — both excluded on diligence - #51
Merged
Conversation
Investigated the two richest extra taste datasets to sharpen the heads; both fail the commercial-clean test, for different reasons. No source added — taste stays on ChemTastesDB + SweetenersDB. The diligence is the deliverable. - FartDB (HuggingFace, ~31k tastants, largest public set): MIT badge over a composite of FlavorDB (CC-BY-NC-SA) + SciFinder (CAS, proprietary) + Tas2R-DB (ACS). The badge can't relicense data FartLabs doesn't own — the OpenPOM GS-LF trap. - PlantMolecularTasteDB (Gradinaru 2022, Front. Pharmacol.): the ARTICLE is CC-BY, but the DATABASE is web-only + i-Depot IP-registered with no open data license — verified by checking the source before merge (article-CC-BY != database-CC-BY). Documented in SOURCES.md + DATA-SOURCES.md; build_taste_dataset.py warns off both. Signed-off-by: Austin L. <86896075+rvnminers-A-and-N@users.noreply.github.com>

Item from the 'sharpen taste' track: investigated the two richest extra taste datasets. Both fail commercial-clean diligence — no source added. Taste stays on ChemTastesDB + SweetenersDB. The rigorous negative result is the deliverable (and it protects the commercial path).
FartDB — excluded
FartLabs/FartDB(~31k molecules, the largest public tastant set, behind the 2025 npj Science of Food model) wears an MIT badge over a composite of FlavorDB (CC-BY-NC-SA) + SciFinder (CAS, proprietary) + Tas2R-DB (ACS). The badge can't relicense data FartLabs doesn't own — the OpenPOM GS-LF trap.PlantMolecularTasteDB — excluded (caught by verifying before merge)
Initially looked clean (Frontiers 2022, CC-BY). But checking the source first: the article is CC-BY, while the database is web-only (plantmoleculartastedb.org), carries no open data license, and the authors registered an i-Depot IP/authorship claim. Article-CC-BY ≠ database-CC-BY — same family as Pyrfume/OpenPOM. Would need an explicit commercial grant from the authors.
Changes
SOURCES.md+DATA-SOURCES.md: both sources documented as evaluated-and-excluded, with the precise reason; priority note updated ("no additional commercial-clean taste source currently available").build_taste_dataset.py: docstring warns the next contributor off both. (An earlier draft of this PR added a PlantMolecularTasteDB loader; removed once the source proved unclean.)ruffclean;build_taste_dataset.pyimports fine.
