SRI for Open Journal Systems
Automatically register a persistent ScitekHub Research Identifier for every article you publish — directly from your OJS installation, the same way you already know from Crossref or DataCite.
What the plugin does
The SRI-Plugin is a thin client to the SRI registration API. It installs inside your own OJS server, registers articles the moment they are published, and surfaces the result inside OJS — while never getting in the way of publishing.
Automatic registration on publish
When an article is published, the plugin calls the SRI registration API automatically — the same way you already expect from Crossref or DataCite. No re-typing metadata by hand.
Scoped API key only
Authenticates with a narrow identifier:register API key from the SRI dashboard. If a key is ever compromised, revoke or rotate it in seconds — no re-pasting needed on renewal.
Best-effort, never a blocker
If SRI is down, or your membership/quota/prefix has a problem, the article still publishes normally. The plugin records a clear reason you can retry later.
Status inside OJS
See Not registered, Pending SRI review, Active, or Failed (with the exact reason) right in the submission screen. Manual register and refresh actions are one click away.
Back-catalog registration
Register existing articles too, with the built-in Register Back Catalog screen. It uses the bulk API, so it stays within your key's rate budget even for large archives.
Citation meta tags
Emits citation_sri meta tags on the article page for Google Scholar and other indexers — just like the citation_doi tags OJS already emits for DOIs.
Installation
Three steps, then it runs on autopilot. Download the installable package matching your OJS version directly from our GitHub Releases, or contact our team for guided setup.
Create a scoped API key
Log into the SRI dashboard, open Settings → API Keys, and create a key with the identifier:register scope only (least privilege). Copy the key — it is shown only once.
Install the plugin
In OJS, go to Settings → Website → Plugins → Upload a new plugin and upload the package matching your OJS version. Enable it under Public Identifier Plugins.
Paste the credentials
Open the plugin settings and paste the API base URL, your scoped API key, and your numeric SRI prefix. Choose how you want suffix generation to behave (default, custom pattern, or manual).
OJS version compatibility
Choose the package matching your OJS version. OJS 3.3 and 3.5 are the priority long-term support lines; 3.4 is also fully supported.
| OJS version | Support | Package |
|---|---|---|
| 3.5.x | Primary (LTS) | sri-pubid-3.5.tar.gz |
| 3.4.x | Primary | sri-pubid-3.4.tar.gz |
| 3.3.x | Supported (LTS, min. 3.3.0-18) | sri-pubid-3.3.tar.gz |
Minimum OJS 3.3 patch: 3.3.0-18. Earlier 3.3.x releases had disclosed vulnerabilities. A plugin cannot compensate for an unpatched host — keep OJS itself updated.

The plugin enforces no new business rules. Every check below is handled by the SRI backend and merely surfaced inside OJS with a friendly reason. In every case, the article still publishes.
| Condition | HTTP | Shown in OJS | Article still publishes? |
|---|---|---|---|
| API key invalid or revoked | 401 | Reconnect your SRI API key | Yes |
| Account suspended or closed | 403 | Account suspended — contact SRI support | Yes |
| Membership expired | 402 | Your SRI membership has expired — renew to register | Yes |
| Quota exhausted | 402 | Quota exceeded — upgrade your plan | Yes |
| No active prefix for this account | 403/404 | Prefix not set up — contact SRI support | Yes |
| All checks pass, auto-approve off | 201 | Awaiting SRI review | Yes, with a pending badge |
| All checks pass, auto-approve on | 201 | SRI shown live on the article page | Yes, fully registered |
Developer docs
Everything the plugin uses is a documented public API: registration, metadata formats (JSON-LD, Dublin Core, DataCite, BibTeX, RIS, Schema.org, CSL-JSON), status polling, and webhooks.

No OJS? You can still register SRIs through the dashboard or the bulk upload tool. The plugin simply automates this for OJS journals — it is never required.
