Your Crossref DOI metadata has gaps. See which ones are costing you citations.
Paste your Crossref prefix or ISSN. The Galoa Metadata Refiner checks every DOI for missing ORCID, funder, abstract, and license data, then ranks them by citation impact so you know exactly where to start. Free, no account needed.

We analyze your scope
The engine queries Crossref's API for every DOI in your prefix, checks each one for missing fields, and weights each gap by citation count.
You receive a prioritized report
A Health Score from 0 to 100, a field-by-field breakdown, and a ranked list of the specific DOIs to fix first — delivered to your inbox.
Not a list of errors. A plan.
The Participation Report shows you volume. The Refiner shows you priority.
Health Score (0–100)
An aggregate score across all DOIs in your scope. Compare across runs to track improvement over time.
Field breakdown
Which fields are missing across your catalog: abstract, ORCID, funder, license, open references. Percentages by field, not just totals.
Prioritized DOI list
Each gap ranked by citation impact. Spend your first hour on the ten DOIs that will move the needle most.

On the roadmap
One scan is useful.
Continuous monitoring is a competitive advantage.
The next phase adds persistent tracking, regression detection, and public quality signals — so your metadata health becomes something you maintain, not something you discover by accident.
Continuous monitoring
Track your Health Score over time. Catch new deposit gaps the moment they appear, not months later.
Regression alerts
Get notified the moment a specific DOI's metadata quality drops — by email, webhook, or Slack.
Embeddable quality badges
Display your journal's live Health Score on your site. A public signal of technical rigor for readers, indexers, and funding bodies.
Vote on features and follow updates on the public board.
Built inside the Crossref infrastructure since 2015.
Galoa has been a Crossref Sponsoring Member since 2015 and an ORCID Institutional Member since 2025. The Metadata Refiner is not a third-party interpretation of the metadata standards — it runs on the same domain knowledge that has powered DOI assignment, metadata compliance, and proceedings publishing for scientific societies across Latin America for over a decade.
Frequently asked questions
Answers to what editors and journal managers ask before running their first scan.
What is a good Crossref Health Score?
Scores above 85 indicate strong metadata compliance across funder, ORCID, abstract, and license fields. Most journals starting out sit between 40 and 70. Your score improves as missing fields get registered through Crossref deposits.
How often should I check my metadata?
Monthly for active journals, quarterly for archives. Metadata gaps accumulate as new DOIs are deposited, and funder and ORCID fields are usually the first to slip.
Why does citation weighting matter for prioritization?
A missing funder field on a paper with 300 citations has far more discoverability impact than the same gap on a paper with 3 citations. The Refiner ranks by impact, so you fix what moves your aggregate score fastest.
Does the Refiner submit corrections to Crossref for me?
Not yet. The Refiner identifies gaps and prioritizes them. Deposit corrections still go through your normal Crossref workflow. Automated correction is on the roadmap, and you can vote for it on the public feature board.
Is my data stored?
No. You paste a prefix or ISSN, we query Crossref's public API, and the report is sent to the email address you provide. Nothing persists across runs, and no account is created.
How is this different from Crossref's Participation Report?
Crossref's Participation Report shows raw coverage percentages — what is missing across your catalog. The Refiner ranks which specific DOIs to fix first, weighted by citation impact. Volume versus priority.
