OpenAlex Snapshot

Mirror of the OpenAlex scholarly metadata snapshot — a free, open catalogue of 250M+ scholarly works, 100M+ authors, and related entities.

Hosted on HuggingFace via Xet for content-addressable deduplication.

Source: s3://openalex (public, anonymous S3 bucket)

Dataset subsets

Each entity type is a separate subset (config):

Config Description Shards
works Scholarly works (papers, datasets, etc.) 2,127
authors Authors of scholarly works 738
institutions Universities, research orgs 61
publishers Academic publishers 51
sources Journals, repositories, conferences 42
awards Grant/funding awards 20
concepts Legacy concept taxonomy (Wikidata) 3
topics Topic taxonomy 1
domains Top-level topic domains 1
fields Topic fields 1
subfields Topic subfields 1
funders Funding organisations 1

Data format

Each shard is a gzip-compressed JSON Lines file at:

data/{entity}/updated_date=YYYY-MM-DD/part_XXXX.jsonl.gz

The .jsonl.gz extension allows the HuggingFace dataset viewer to detect the inner format automatically. On S3, files are named part_XXXX.gz; the download pipeline renames them on save.

Each line is a JSON object representing one entity record. Fields vary by entity type. See the OpenAlex data model for field definitions.

Example: Work record fields

id, doi, title, display_name, publication_year, type, language, authorships, concepts, topics, keywords, cited_by_count, referenced_works, related_works, locations, open_access, funders, awards, mesh, sustainable_development_goals, counts_by_year, updated_date, and more.

Sync and extraction pipeline

The sync/ directory contains a Python pipeline for downloading from S3 and extracting relationship tables to Parquet:

  1. Download: python3 -m sync.download sync [--entity X] — syncs from s3://openalex (public, anonymous)
  2. Extract: python3 -m sync.extract extract [--entity X] --workers 6 — converts .jsonl.gz to nested parquet sub-tables

Extraction supports --slice-index N --slice-total M to partition work across machines.

Adding new entity types

OpenAlex occasionally adds new entities. To support a new one:

  1. Download: python3 -m sync.download sync --entity {entity}
  2. Schema: Add entity + relationship schemas to sync/schemas.py
  3. Extraction: Add dispatch entry to _ENTITY_DISPATCH in sync/extract.py
  4. Nesting: Add singular→plural entry to _ENTITY_SINGULAR_TO_PLURAL in sync/common.py
  5. Commit: Stage and push
