In the evolving landscape of scholarly communication, Open Science principles call for greater transparency, accessibility, and accountability in research dissemination. Diamond Open Access (OA) publishers play an important role in this transformation. These community-driven initiatives face unique challenges in achieving metadata quality and aligning with Open Science policies. To support this transition, OpenAIRE has developed the Publisher Dashboard – a dedicated service embedded within the OpenAIRE MONITOR platform – under the auspices of the CRAFT-OA project and additional to other deliverables. It enables Institutional Publishing Service Providers and Diamond OA publishing communities to monitor and improve their metadata workflows, assess alignment with Open Science practices, and contribute to a more transparent research ecosystem. The OpenAIRE Publisher Dashboard is a data-driven component of the OpenAIRE MONITOR service, tailored to support Diamond Open Access publishers. It provides actionable insights derived from the OpenAIRE Graph, one of the largest Scientific Knowledge Graphs in the world. The Dashboard allows Diamond Open Access publishers to explore how their content is aggregated, enriched, and exposed in compliance with OpenAIRE Guidelines. While metadata validation is handled at the aggregation level, the quality of this metadata is essential for fully leveraging the functionalities of the Dashboard.

The Publisher Dashboard offers a suite of metrics and indicators designed to provide Diamond OA publishers with actionable insights into their publishing activity and impact. Key features include:

• Umbrella Dashboard Support: In addition to the main publisher dashboard, the service supports individual dashboards for each journal, enabling more granular tracking and self-monitoring of scholarly production.
• Dashboard Analytics: Visual summaries of scholarly publishing activity, including the number of journals published, the journals registered in DOAJ, the volume of peer-reviewed publications, and the scholarly production attributed to Diamond OA journals. It also indicates whether publications appear in repositories, are shared across countries, or are classified under specific Fields of Science (FoS) and assigned Sustainable Development Goals (SDGs). Funding indicators have also been utilised that highlight grant-supported publications, such as those resulting from EC-funded projects.
• Coverage Analysis: Insights into how publications from Diamond OA journals are represented across data sources, including those from other countries and national infrastructures.
• Benchmarking Metrics: Comparative metrics across journals within the publisher to assess performance and visibility.

The Publisher Dashboard is being piloted in collaboration with institutional and community-driven Diamond OA publishing platforms as part of the CRAFT-OA and DIAMAS projects. Use cases include:

• Monitoring scholarly production across Diamond OA journals with transparent metrics and indicators.
• Enhancing the discoverability of journal content in OpenAIRE and EOSC portals.
• Identifying gaps in metadata of the aggregated Diamond Open Access publishers
• Enriching the metadata through the enrichment process of the OpenAIRE Graph’s production workflow.
• Demonstrating alignment with FAIR principles through quantifiable indicators.

Implementing the Publisher Dashboard has revealed several challenges:

• Metadata Diversity: A wide variation in metadata quality and formats, particularly among small and community-run journals.
• Capacity Gaps: Many Diamond OA publishers need training and support to adopt best practices in metadata management and comply with the OpenAIRE Guidelines so that we have a comprehensive aggregation leading to qualitative metrics and indicators.

To address the above challenges in metadata and assist the aggregation of Diamond Open Access publishers and journals, an OJS platform plugin has been developed as a CRAFT-OA deliverable, to ensure compatibility with the OpenAIRE Guidelines v4.0. Additionally, OpenAIRE supports the aggregation through the JATS XML metadata schema.

These insights have informed the development of support materials, community engagement strategies, and the co-design of features that reflect publishers’ real-world needs.

The OpenAIRE Publisher Dashboard supports Diamond OA publishers in understanding the visibility and reach of their scholarly output and contributing to a more open and equitable scholarly ecosystem. By providing qualitative metrics and indicators derived from properly aggregated metadata, the Dashboard enables Diamond OA publishers to view the range of their scholarly production and understand how their journals are positioned within the broader publishing landscape. It will be delivered alongside the broader outcomes of the CRAFT-OA project, including functional OJS plugins and the Diamond Discovery Hub, providing a comprehensive suite of services to enhance Diamond OA publishing infrastructures. Furthermore, the Publisher Dashboard will be part of the Tools and Services offered by the European Diamond Capacity Hub, supporting long-term sustainability and collaboration within the Diamond OA ecosystem.
