Each row is the whole Gene Knowledge Graph on one date — sealed, hashed, and kept at a permanent address. The working catalogue holds 102,686 variants today and is curated continuously; a sealed Gene Knowledge Graph Snapshot is the only form of it that can be quoted, audited or reproduced. The next one is sealed on 26 October 2026.

Every row's record page — its counts and its digest — is public forever, whether or not the file is bought, because a citation nobody can verify is not a citation. Buying a Gene Knowledge Graph Snapshot is a one-off: no expiry, no download limit, and one version is normally enough — you buy the one your work cites. If what you need is queries against today's data, that is API Pro rather than a file.
Each version above carrying a DOI badge is registered with Zenodo, CERN's open-science archive — the same kind of permanent identifier a journal article carries, built to resolve for as long as the DOI system itself exists, independent of mygenelog.com. Every version gets its own versioned DOI, permanently pointing at that exact file and its exact counts; alongside it, one shared concept DOI always resolves to whichever version is newest. Cite the versioned DOI for the specific numbers a piece of work used; cite the concept DOI to mean “the MyGeneLog dataset” in general. Versions sealed before DOI registration began carry no badge — their record pages remain public and citable by URL, just without a DOI.
A snapshot is informational summaries of published research, not medical advice, and not a diagnosis. If you build a product on a snapshot, don't present it as one either — carry the same non-diagnostic framing through to your own users. See Terms of Use.
A frozen, dated copy of the entire MyGeneLog™ dataset — every variant, condition, drug, chemosensory group and topic as they stood on one specific date — packaged as one gzip-compressed JSON file with a SHA-256 digest. The live catalogue keeps growing every day; a snapshot is the one form of it that never changes, which is what a citation actually needs.
Every snapshot from GKG-Snapshot-4 onward is registered with Zenodo, CERN's open-science archive, and gets its own DOI — the same kind of permanent identifier a journal article or a public dataset carries. A URL can go offline; a DOI is built to resolve for as long as the DOI system itself exists, which is the whole point of citing a specific version rather than 'the live site.'
Each sealed version gets its own versioned DOI, permanently pointing at that exact file and its exact counts. Alongside it, one concept DOI is shared across every version ever sealed, and always resolves to whichever is newest. Cite the versioned DOI when you mean the specific numbers your work used; cite the concept DOI when you mean 'the MyGeneLog dataset' in general, whatever version that turns out to be later.
No. The structured fields in a snapshot carry the exact same CC BY 4.0 license as the live API — free to reuse, including commercially, with attribution. What a snapshot sells is the freezing and the permanent, hashed, DOI-backed address, not different rights to the data itself.
Roughly monthly. Each one is a separate, independently purchasable and independently citable file — almost nobody needs more than the single version their own work cites, since a dated version never goes stale for that purpose.
Yes. Every version's record page — its counts, its SHA-256, and its DOI once minted — is public and permanent whether or not the file itself was purchased, because a citation nobody outside MyGeneLog can verify is not a useful citation.
