Wednesday 22nd October 2025—Crossref, the open scholarly infrastructure nonprofit, today releases an enhanced dashboard showing metadata coverage and individual organisations’ contributions to documenting the process and outputs of scientific research in the open. The tool helps research-performing, funding, and publishing organisations identify gaps in open research information, and provides supporting evidence for movements like the Barcelona Declaration for Open Research Information, which encourages more substantial commitment to stewarding and enriching the scholarly record through open metadata.
Welcome back to our series of case studies of research funders using the Grant Linking System. In this interview, I talk with Cátia Laranjeira, PTCRIS Program Manager at FCCN|FCT, Portugal’s main public funding agency, about the agency’s approach to metadata, persistent identifiers, Open Science and Open Infrastructure.
With a holistic approach to the management, production and access to information on science, FCCN|FCT’s decision to implement the Grant Linking System within their processes was not simply a technical upgrade, but a coordinated effort to continue building a strong culture of openness. With the mantra “register once, reuse always”, FCCN|FCT efforts to embrace open funding metadata was only logical.
Repositories are home to a wide range of scholarly content; they often archive theses, dissertations, preprints, datasets, and other valuable outputs. These records are an important part of the research ecosystem and should be connected to the broader scholarly record. But to truly serve their purpose, repository records need to be connected to each other, to the broader research ecosystem, and to the people behind the research. Metadata is what makes that possible. Enhancing metadata is a way to tell a fuller, more accurate story of research. It helps surface relationships between works, people, funders, and institutions, and allows us as a community to build and use a more connected, more useful network of knowledge - what Crossref calls the ‘Research Nexus’.
The Crossref Grant Linking System (GLS) has been facilitating the registration, sharing and re-use of open funding metadata for six years now, and we have reached some important milestones recently! What started as an interest in identifying funders through the Open Funder Registry evolved to a more nuanced and comprehensive way to share and re-use open funding data systematically. That’s how, in collaboration with the funding community, the Crossref Grant Linking System was developed. Open funding metadata is fundamental for the transparency and integrity of the research endeavour, so we are happy to see them included in the Research Nexus.
This June, we presented at the Beijing International Book Fair (BIBF) and connected directly with our growing community in China. With a surge of interest from Chinese publishers and partners, it was clear: there’s a strong and rising curiosity around how metadata plays a vital role in maintaining the integrity of the scholarly record.
And we were not alone: our incredible Crossref Ambassadors based in the region joined us at the booth, and together we hosted visitors and answered questions. Throughout the fair, we engaged in passionate conversations, provided metadata guidance, and shared our knowledge as part of a panel session focused on how metadata supports scholarship. Ms. Ran Dang, Editorial Director at Atlantis Press (Springer Nature), supports Crossref outreach and advocates for Open Access and Open Science. Ms. Xiaofeng Guo, Director at Sin-Chn Scientific Press, leads DOI infrastructure efforts in China and supports Crossref members across the region. Mr. Gantulga Lkhagva, Founder and CEO of Mongolian Digital Knowledge Solutions and MongoliaJOL, works to strengthen local scholarly publishing and promote metadata best practices.

This was the first time some of us had met in person after years of online collaboration, and the sense of connection and shared purpose was energising. Our Ambassadors also contributed to this post, sharing their favourite moments, key takeaways, and stories from the fair.
A snapshot from the panel discussion
During BIBF, we hosted a panel session focused on the role of metadata in supporting scholarship. Ms. Alicia Wang, Vice President - CNPIEC Kexin Technology Co., Ltd, Robbykha Rosalien, Membership Support Specialist - Crossref, Johanssen Obanda - Community Engagement Manager - Crossref, and our Ambassadors joined the panel, and we were glad to have a mix of Crossref members, Metadata Plus users, and curious participants join the discussion.

Key questions from the session included the status of open abstracts in Crossref, how retracted articles affect citation tracking and research integrity, and what happens when DOIs no longer resolve due to unmaintained landing pages.
Robbykha explained our DOI resolution and archival systems, clarifying that DOIs are designed to always resolve, even when the original content moves or becomes unavailable. We also touched on the work Crossref is doing to support transparency around retractions, and the goals of The Initiative for Open Abstracts, which aims to make research summaries more accessible.
Metadata Plus use cases from China
Two of our Metadata Plus users were present during the panel and generously shared how they are leveraging Crossref metadata in their work.
Jie He from ScienceRiver described how their team translates Crossref metadata from English into Chinese, making it possible for users in China to search for relevant academic literature originally published outside the mainland. Their efforts open up global research to local audiences, bridging language and accessibility gaps. This conversation also led to broader discussions about multilingual metadata and the work our Metadata Advisory Group hopes to support in this area.
Eurasia Academic Publishing Group, based in Hong Kong, talked about using Crossref metadata coupled with AI approaches to develop a tool for readers, editors, and institutions to help assess the integrity of research articles and detect paper mills.
Reflections from our Ambassadors and the community
One common thread throughout our time at BIBF was the recognition that many of our resources, documentation, and support materials are still primarily in English. For Chinese-speaking community members who are new to Crossref or metadata concepts, this creates a pretty steep learning curve. We heard this clearly, and we know there’s work to do in making our services more accessible across languages.
From personal highlights to fascinating conversations, here’s what some of our Ambassadors had to say:
I am very happy to have met with colleagues from Crossref and several Ambassadors from Asia! We have met many times online, but this was the first time we met face-to-face and worked together to engage with our members and host events! I learned a great deal from our face-to-face exchanges, including updates on Crossref’s latest use cases, industry development trends, and even information about my colleagues’ hometowns. We built friendships and successfully participated in the first BIBF event for Crossref, which was the biggest takeaway!
At the BIBF exhibition and events, we had good conversations with our Chinese partners and some members, and learned about actual application needs and use cases, which was very helpful to me. Most of the people I met spoke Chinese, but their publishers or institutions may have come from countries and regions outside mainland China, such as Singapore, Hong Kong, and Taiwan.
I also participated in the BIBF Forum events held before the exhibition, including the PubTech Conference, the first STM Asia-Pacific Conference, and the networking dinner. These three events were jointly organised by China National Publications Import and Export (Group) Corporation (CNPIEC), STM, and the Chinese Society of China University Journals (SCUJ). During the events, I heard about the latest developments in the publishing industry and gained valuable insights into hot topics. I also met many new and old friends and partners, some from China and others from around the world. Interacting with them not only allowed me to reminisce about the past but also provided me with new perspectives and expanded my professional network.
Discussion with Ms. Bo Li from China Education Publication Import & Export Corporation (CEPIEC) on matching papers with their funding grants from China. This is an excellent use case for Crossref’s Grant Linking System (GLS) service and related metadata. We introduced the GLS service and Crossref metadata to Ms. Bo Li and will follow up with her and her colleagues to help them use Crossref’s metadata to complete this task more easily.
Discussion with Dr. Zhu Xuefeng. Their team has developed an application that identifies research integrity issues in journals and articles. They primarily utilise Crossref metadata (including article metadata and retraction observation data), withdrarXiv, ORCID and Research Organization Registry (ROR) data, among others. By linking and integrating these data, they calculate the research integrity risk of relevant journals and articles, providing a reference for authors submitting manuscripts, editors reviewing manuscripts, and institutions monitoring research integrity issues.
At the Crossref BIBF event, Ms. Wang Xuan, Vice President of CNPIEC Kexin Technology Co., Ltd, a Crossref sponsor in China, discussed the strong demand for reliable data sources when applying AI in the field of scientific research, as well as how Crossref metadata can provide strong support. She proposed that all AI products focusing on scientific research should show the original DOIs for the academic resources they cite in the results they provide to users, to enhance the reliability and traceability of data sources. She committed that her company, Ke Xin, as a provider of research AI assistants, will implement this functionality in its products and hopes to promote this as a best practice to all research AI application developers and providers. This reflects that, as cutting-edge technology advances and requirements for research integrity and compliance continue to rise, Crossref metadata continues to play an important role in scholarship and will become increasingly extensive and indispensable.
