Zenodo is a free, open-access repository developed by CERN that allows researchers and publishers to assign Digital Object Identifiers (DOIs) to their publications — completely free of charge. Unlike commercial DOI providers, Zenodo offers unlimited DOI registration with no annual fees, making it an ideal solution for academic journals operating on limited budgets.

With a Zenodo DOI, your articles gain permanent, citable identifiers that are indexed by major academic databases, ensuring long-term discoverability and accessibility for the global research community.

How Zenodo DOI Works — What to Expect

It’s important to understand how Zenodo DOIs differ from services like CrossRef or DataCite. When you assign a DOI through Zenodo:

• The DOI link (e.g., https://doi.org/10.5281/zenodo.12345) resolves to the Zenodo record page, not directly to your journal website.
• Zenodo stores a copy of your article (PDF and metadata) as an open-access archive on its platform.
• Your journal URL is included in the Zenodo metadata, so readers can easily find and visit your journal from the Zenodo page.

This is different from CrossRef, where the DOI link points directly to the article on your journal website. With Zenodo, your article gains an additional presence on a trusted, CERN-hosted repository — providing extra visibility, long-term preservation, and credibility. Many journals use Zenodo DOIs as a cost-free alternative to commercial DOI services, and the Zenodo landing page serves as a secondary access point that complements your journal.

The Challenge: A Tedious Manual Process

While Zenodo provides an excellent free DOI service, the process of depositing articles is entirely manual. For each article, journal editors must:

1. Log in to Zenodo and create a new upload to reserve a DOI
2. Copy the DOI and add it to the article’s PDF and OJS metadata
3. After publishing the article in OJS, return to Zenodo
4. Manually enter all metadata — title, authors, affiliations, abstract, keywords
5. Fill in publishing information — journal name, ISSN, volume, issue, page numbers
6. Upload the PDF file
7. Review everything and publish the record

This process takes 10–15 minutes per article and is highly prone to errors — typos in author names, missing affiliations, incorrect page numbers, or forgotten keywords. For journals publishing 30–100+ articles per year, this becomes a significant burden on editorial staff.

Our Solution: Zenodo DOI Sync Plugin for OJS

Based on direct feedback and requests from our OJS clients and the academic publishing community, we developed the Zenodo DOI Sync Plugin — a comprehensive integration that automates the entire Zenodo deposit workflow directly from within OJS.

What previously took 10–15 minutes of manual data entry per article now takes a single click and a few seconds. All metadata is pulled directly from OJS, eliminating human error and ensuring consistency between your journal and Zenodo records.

We continue to actively develop this plugin and provide dedicated support based on user feedback and evolving Zenodo API requirements.

Key Features

🔑 Secure Token-Based Authentication

The plugin connects to Zenodo using your personal access token — no passwords stored, no complex OAuth flows. Simply generate a token from your Zenodo account and paste it into the plugin settings. Each journal can have its own Zenodo account and token.

🏷️ One-Click DOI Reservation

Reserve a DOI from Zenodo without leaving OJS. The DOI is automatically saved to the article’s identifier field. No need to switch between OJS and Zenodo.

📋 Automatic Metadata Synchronization

With a single click, the plugin transfers all article metadata to Zenodo:

• Title — in the article’s original language
• Authors — with full names, affiliations, and ORCID identifiers
• Abstract — with HTML formatting preserved (bold, italic, paragraphs)
• Keywords — all subject keywords from the article
• Journal Information — journal name, ISSN, volume, issue, page numbers
• Publication Date — from the OJS publishing date

📄 Automatic File Upload

The plugin automatically uploads all galley files (PDF and others) from OJS to Zenodo. It handles file cleanup — removing old files before uploading new ones — ensuring your Zenodo record always matches your OJS content.

🌐 Zenodo Community Integration

If your journal has a Zenodo community, the plugin can automatically associate new deposits with your community. Simply enter your community slug in the settings, and every new DOI reservation will be linked to your community page.

🚀 Publish to Zenodo from OJS

Once your article is published in OJS, you can publish it to Zenodo with one click. The plugin handles metadata sync, file upload, community review submission, and publication — all in a single operation.

📊 DOI Management Dashboard

A dedicated management page in the OJS sidebar gives you a complete overview of all articles and their Zenodo status:

• Filter by Zenodo status (Draft / Published), OJS status, or issue
• Search by title, DOI, or article ID
• Sort by any column
• Sync or publish individual articles directly from the dashboard
• Color-coded status badges for instant visual overview

🔄 Legacy DOI Scanner

Already have articles with Zenodo DOIs that were created manually? The built-in scanner finds all existing Zenodo DOIs in your journal, checks their current status on Zenodo (draft or published), and updates the local database — so you can manage everything from one place.

🌍 Multi-Language Support

The plugin interface is fully translated in English and Turkish, with support for additional languages. All labels, messages, and notifications adapt to your OJS language setting.

🔒 Role-Based Access Control

Only Site Administrators and Journal Managers can access Zenodo features. Authors, reviewers, and other users cannot see or interact with DOI management tools.

The post Why Zenodo DOI for Academic Journals? first appeared on OPEN JOURNAL SYSTEM SERVICES.

To achieve full OpenAIRE compliance, OJS journals must accurately classify their content using the COAR Resource Type system.

What Is the COAR Resource Type Classification System?

In the world of open-access publishing, content is only as visible as the metadata behind it.
The COAR Resource Type Classification System — developed by the Confederation of Open Access Repositories (COAR) — provides a unified way to describe what kind of resource a publication really is.

Whether it’s a research article, dataset, software package, or interactive web resource, this classification ensures that repositories, harvesters, and indexing systems like OpenAIRE, Crossref, or ORCID can accurately recognize and categorize your content.

It’s not just a list of labels — it’s the universal vocabulary of academic content.

Why It Matters

• ✅ OpenAIRE Compliance: Ensures your OJS journal metadata meets European Open Science standards.
• 🌐 Global Discoverability: Makes your publications compatible with international repositories and aggregators.
• ⚙️ Consistent Metadata: Standardizes resource descriptions across OJS, DSpace, Zenodo, and other open repositories.
• 📊 Interoperability: Enables seamless exchange of records via OAI-PMH and other metadata protocols.

How It Works in OJS

The OpenAIRE plugin for OJS integrates COAR Resource Types directly into your journal’s metadata.
When activated, the plugin automatically maps each article type to a corresponding COAR category — ensuring that your repository exports valid and compliant records through the OAI-PMH interface.

This not only saves editorial time but also guarantees that your journal meets the OpenAIRE Guidelines for Literature Repository Managers (v4.0).
