Metadata completeness — one score
Any journal by its ISSN, any DOI prefix, any Crossref member: how much of the metadata indexes read is on the record, what is missing, and who fixes it. Free, no account — every figure is Crossref's own.

Read from Crossref just now — 23 Oct 2026, 03:50. Counted over the journal's registered DOIs, current and backfile weighted by their counts.
The seven signals indexes read
Of the 0 registered DOIs, how many carry each one. The impact numbers sum to 100 and make the score — the weighted share of what is there; a signal Crossref gave no figure for is left out of the score, never counted as 0.
| Signal | Share | Without it | What it means — and who fixes it |
|---|---|---|---|
| Reference lists impact 22 |
0% | none | The engine deposits the reference list of each article — this is what feeds Cited-by, OpenAlex and Scholar. Run the Reference Booster / DOI Doctor. The engine deposits it. |
| Abstracts impact 18 |
0% | none | No abstract in the record means weaker discovery everywhere. DOI Doctor reads it from the PDF and deposits it. The engine deposits it. |
| Licences impact 16 |
0% | none | A licence in the record is what marks the article open access and DOAJ counts it. DOI Doctor deposits the licence your article page states. The engine deposits it. |
| ORCID iDs impact 14 |
0% | none | Author ORCIDs tie the work to its authors for ORCID, funders and OpenAlex. The engine deposits them when the article page carries them; otherwise add them in OJS first. Needs the value on the page first. |
| Author affiliations impact 12 |
0% | none | A machine-readable affiliation is what gives the institution credit and lets NIRF / NAAC counts find the work. Add affiliations to the article metadata; the engine deposits them. Needs the value on the page first. |
| ROR institution ids impact 10 |
0% | none | A ROR id (ror.org) is the machine-readable name of the institution — the strongest institutional-credit signal there is. Add each institution's ROR to the affiliation; the engine deposits it with the affiliation. Needs the value on the page first. |
| Funder data impact 8 |
0% | none | Funder ids link the work to the grant that paid for it — read by funders and OpenAlex. Add the funder to the article metadata; the engine deposits it. Needs the value on the page first. |
Beside the score
The other elements of Crossref's participation report. They are shown here, and they are not part of the score.
| Element | Share | Without it | What it is for |
|---|---|---|---|
| Award numbers | 0% | none | The grant number beside the funder — what lets a funder find the work its grant paid for. |
| Crossmark update policy | 0% | none | Crossmark tells a reader, on the article itself, whether it has since been corrected or retracted. |
| Similarity Check URLs | 0% | none | A full-text link that Crossref's Similarity Check service reads, so new manuscripts can be compared against this article. |
| Text-mining URLs | 0% | none | A full-text link for text and data mining — how Crossref and mining services reach the article itself. |
Nothing to fix in the seven
Every signal Crossref gave a figure for is complete on every record counted. Keep the record that way: DOI Doctor checks every DOI again on its own schedule.
Every DOI, yes or no — the gap list
This list is member-wide. Crossref keeps the per-DOI listing by member, so the file holds every journal article of the member that owns these DOIs — this journal's and any other journal it publishes. The ISSN column tells them apart.
⬇ Gap list — every DOI, yes/no per element (CSV)The same file as "What Crossref holds about you" makes: up to 5,000 records (5 requests of 1,000, Crossref's maximum per request); a member with more gets the first 5,000 as Crossref lists them, and the file says so. A finished list is kept for 6 hours; a fresh read counts as one lookup (12 an hour from one place; 60 for a signed-in account).
Before and after
First recorded 23 Oct 2026: 0 (E). One reading so far — the next one, on another day, shows the after, signal by signal.
Every record kept — one a day, the day's last reading — each a page of its own you can send as proof: 23 Oct 2026 — 0 (E)
What large publishers reach, read on 16 Oct 2026
Each scored exactly as any member is scored here — from its own Crossref member record, by the same seven signals and weights. Names are Crossref's own. The median of the 12 is 41.
Research and Practice in Anesthesiology - Open Journal (RPAOJ): 0 — 41 points below the large publishers' median, and 32 points below all of Crossref.
How the score is made
- Reference lists — impact 22

- Author affiliations — impact 12
- ROR institution ids — impact 10
- Funder data — impact 8
The score is the share of each signal on the record, weighted by its impact (the impacts sum to 100). A signal Crossref gives no figure for is left out and the rest are weighed as before — never counted as 0. Grade A from 85, B from 70, C from 55, D from 40, otherwise E. A journal is read off Crossref's journal record (its current and backfile DOIs, weighted by how many each holds); a prefix and all of Crossref by counting every DOI with Crossref's own has-… filters; a member off its member record, as What Crossref holds about you reads it. The members door's engagement dashboard prints the same score from the same functions.
