Sources and acknowledgements
About › Sources & acknowledgements
Everything on this site is derived from public archives and open literature; this page names those sources and their terms, the software and models the pipeline uses, the funding, and the other projects that curate human-microbiome metadata — with an honest assessment of what each could add to the catalog and how it would join.
About this page
Last reviewed 2026-09-28.
Development of Microbiome Repo is supported by a grant from Anthropic to the Olm Lab (University of Colorado Boulder) for organising human microbiome metadata.
Data sources
| source | what we take from it | terms |
|---|---|---|
| European Nucleotide Archive (ENA) / INSDC (SRA, DDBJ) | Study, sample, run and BioSample records and attributes for every registry study (portal API); the archive metadata is route R1. | INSDC: free and unrestricted access to all records. |
| NCBI BioProject and BioSample | BioProject records (titles, descriptions, publications, organisations) and BioSample attributes; E-utilities. | NCBI public-domain data policy. |
| Europe PMC | Paper ↔ accession links, abstracts, open-access full text (JATS) and supplementary files behind routes R2, R3 and R4; author lists. | Europe PMC open-access subset; individual article licences apply to reuse of text. |
| Sandpiper (SingleM community profiles of public metagenomes) | Per-run community profiles and the count of profiled runs per study; profiles shown for the infant studies. | CC-BY (Woodcroft et al. 2025). |
| curatedMetagenomicData (cMD) | Gold standard for the infant-field extraction evaluation (age, delivery mode, preterm status precision) and the 22 infant BioProjects used for study-level recall. | Artistic-2.0 (Bioconductor package); data via ExperimentHub. |
| UBERON | Anchors of the body-site vocabulary (config/vocab/body_sites.yaml). | CC-BY 3.0. |

Software and models
| component | role | licence |
|---|---|---|
| DuckDB-WASM | In-browser SQL over the parquet tables (sample and registry explorers); pinned 1.29.0 from jsDelivr. | MIT. |
| DataTables and jQuery | Sortable study, cohort and scope tables. | MIT. |
| Apache Parquet / Arrow, pandas, DuckDB, Jinja2, Python-Markdown | Pipeline and site generator (microbiome_repo-pipeline). | Apache-2.0 / BSD / MIT (see the repository). |
| Anthropic Claude models | Model-assisted classification (registry), key triage (R1), value normalisation, cohort-statement extraction (R3, R4) and adjudication — always with a verbatim evidence quote; roles and model ids in config/models.yaml and on every model-derived row. | Anthropic usage policies. |
External curated resources incorporated
Each resource, what it offers, how we join it and the projects that use it: External resources.
Other groups have curated human microbiome metadata before us. Where their per-sample or per-study annotations join our samples through archive accessions, we incorporate them as route R2 evidence rows — evidence_source = external.<resource>, the locator a link to the record at the source, the quote the source's raw value — after the study's own supplementary tables in precedence (a sample's own archive attribute always wins). We are grateful to these projects; please cite them when you use values that carry their evidence source.
Acknowledgement. We gratefully acknowledge the teams behind African Human Microbiome Portal (H3ABioNet), BugSigDB, curatedMetagenomicData 3 (cMD 3), GMrepo v3, HMP / iHMP data portal, HumanMetagenomeDB, mBodyMap, Meta2DB (LLNL), MicrobeAtlas, MicrobiomeDB (VEuPathDB): their curation work is incorporated here as route-R2 evidence, every incorporated value links back to its source record (evidence_source = external.<resource>), and users of those values should cite the reference listed for the resource alongside this catalog. Resources that publish no licence are redistributed with attribution only; if you maintain one of them and prefer different terms, open an issue and we will comply.
