## UniRef90

`representatives/uniref90.fasta` derives from UniRef release 2023_02. UniProt
applies [CC BY 4.0](https://www.uniprot.org/help/license) to copyrightable
database content. Attribute the UniProt Consortium / UniRef, retain its notice,
link to the source where practical, and state the processing changes.

## MGnify

`representatives/mgnify.fasta` derives from the official MGnify Protein Database
2023_02 archive. It remains governed by the
[EMBL-EBI Terms of Use](https://www.ebi.ac.uk/about/terms-of-use/) and applicable
original-owner rights. Attribute EMBL-EBI MGnify and the original contributors.
Lumin Science does not apply a new Creative Commons license to these records.

## OMG/IMG

`representatives/omg_img.fasta` contains numeric-accession JGI/IMG protein CDS
rows from [`tattabio/OMG`](https://huggingface.co/datasets/tattabio/OMG), after
removing its `ERZ` MGnify-origin rows. The direct distribution declares CC
BY-SA 4.0. Attribute the OMG authors/TattaBio, JGI/IMG, and original
contributors; retain the license and modification notices.

## Derived cluster maps

`clusters/**`, receipts, manifests, and build documentation are Lumin Science
derived database metadata offered under CC BY-SA 4.0. The cluster maps contain
SHA-256 digests rather than member sequences or original accessions. Applying
the maps to upstream data does not replace the upstream terms for the recovered
records.

## Processing changes

Records were normalized, quality filtered, globally exact-deduplicated with
source membership retained, and clustered independently per source at 70%
sequence identity and 80% shorter-sequence coverage. The data in this RAW
repository have not yet been evaluation-decontaminated.
