OpenAlex Enrichment

Add OpenAlex metadata (citations, OA, topics, SDGs, references) by DOI.

Overview

Enriches any bibliographic table with metadata from OpenAlex, matched by DOI. DOIs are sent in batches (OpenAlex OR-filter, up to 50 per request) and the matching works are merged back, adding oa_ columns: citation count, open-access status, topics / fields / domains, concepts, Sustainable Development Goals, referenced works (for citation networks), yearly citation counts and author institutions. The run is cached on disk, so it can be stopped and resumed without re-fetching.

Run it right after Bibliographic Data when your export lacks citations, references or topical metadata (e.g. a plain Scopus title list), or to attach OpenAlex IDs needed by the citation-network widgets.

Inputs

Data (Table) — bibliographic table; must contain a DOI column.

Outputs

Enriched Data (Table) — the input table plus the selected oa_ columns.

Controls

DOI column — the column holding DOIs; these are the keys matched against OpenAlex.
Email (polite pool) — your e-mail address. OpenAlex’s polite pool gives faster, more reliable responses; optional but recommended.
Batch size — number of DOIs per API request (max 50). Larger = fewer requests.
Delay (s) — pause between requests, to stay within rate limits.
Fields to add — checkboxes selecting which oa_ groups to fetch (citations, OA status, topics/fields/domains, concepts, SDGs, referenced works, counts-by-year, institutions). Fewer fields = faster.

Actions: Select All / Deselect All (toggle the field checkboxes), Enrich from OpenAlex (start), Cancel (stop a running fetch).

What it produces

The same documents with extra oa_ columns. Common follow-ups: Discipline Analysis and SDG Identifier (use the topic/SDG columns), and Citation Network / Historiograph (use oa_openalex_id + oa_referenced_works).

Tips

Provide an e-mail for the polite pool to avoid throttling on large corpora.
Time-series widgets need the counts-by-year field (oa_counts_by_year).
