Crossref: The sustainable source of community-owned scholarly metadata
This paper describes the scholarly metadata collected and made available by Crossref, as well as its importance in the scholarly research ecosystem. Containing over 106 million records and expanding at an average rate of 11% a year, Crossref’s metadata has become one of the major sources of scholarly data for publishers, authors, librarians, funders, and researchers. The metadata set consists of 13 content types, including not only traditional types, such as journals and conference papers, but also data sets, reports, preprints, peer reviews, and grants. The metadata is not limited to basic publication metadata, but can also include abstracts and links to full text, funding and license information, citation links, and the information about corrections, updates, retractions, etc. This scale and breadth make Crossref a valuable source for research in scientometrics, including measuring the growth and impact of science and understanding new trends in scholarly communications. The metadata is available through a number of APIs, including REST API and OAI-PMH. In this paper, we describe the kind of metadata that Crossref provides and how it is collected and curated. We also look at Crossref’s role in the research ecosystem and trends in metadata curation over the years, including the evolution of its citation data provision. We summarize the research used in Crossref’s metadata and describe plans that will improve metadata quality and retrieval in the future.

MIRA — the structure layer for a shared research graph
Research ships as a sealed document. MIRAfying it makes a graph of signed, citable records anchored on the actual data artifacts — so analyses compound without flattening the nuance.

SemRepo: A Knowledge Graph for Research Software and Its Scholarly Ecosystem
We present SemRepo, an RDF knowledge graph comprising over 81 million triples describing nearly 200,000 GitHub repositories associated with scientific research. SemRepo captures repository-level metadata, such as contributors, issues, and programming languages, and interlinks this information with external scholarly knowledge graphs. In particular, repository authors are linked to their profiles in SemOpenAlex, repositories are connected to scholarly publications in LPWC, and research artifacts, such as datasets and experiments, are linked via MLSea-KG. This integration enables queries that span publications and their scholarly artifacts, which are typically fragmented across separate platforms. SemRepo supports analyses that are difficult to perform with existing resources in isolation, including provenance reconstruction across repositories and publications, as well as the systematic identification of risks to research reproducibility and software sustainability. By unifying research software with its scholarly context in a single graph, SemRepo provides an important infrastructure for large-scale analysis of software within the broader scientific research ecosystem.

Two billion citation links in Crossref help research travel further - Crossref
We’ve recently reached an important milestone for the research nexus: the works in our metadata corpus are now connected with over 2 billion citation links! This is a great opportunity to share a dedicated dataset and discuss why these are important for science.

Manuscript submission systems and metadata completeness in Crossref: Patterns and associations
The importance of open research information, particularly publication metadata, is widely recognised. Crossref is one of the most important infrastructures for registering open metadata as part of DOI record registration. It is widely known, however, that the metadata of many publications is far from complete, with many publishers making certain metadata openly available, but failing to do so for other metadata elements. Publishers’ ability to register this metadata with Crossref depends on their capacity to capture and retain this data in their production workflows. Manuscript submission systems are an important, yet largely overlooked, factor in the extent to which publishers make metadata available through Crossref. In this paper, we present the results of an analysis investigating the relation between the level of metadata that publishers deposit with Crossref and the submission systems that they deploy for their journals. We have looked at the 153 publishers with the largest amounts of publications in Crossref and concentrate on the four most commonly used systems: Editorial Manager, ScholarOne, Open Journal Systems (OJS) and eJournalPress. We show that some submission systems appear better suited to capturing certain metadata elements. However, there are always cases where publishers using the same system differ widely in the level of metadata they register, suggesting that technology is not the only prohibiting factor and other considerations are at play.
The Gradual Merging of Repository and CRIS Solutions to Meet Institutional Research Information Management Requirements
Much has been said in recent times about the alleged dichotomy between Institutional Repositories (IRs) and Current Research Information Systems (CRISs). According to this highly ideological argument, IRs would be the platforms to support the non- commercial initiative jointly carried out by HEIs – and specifically their Libraries – in order to freely disseminate their research outputs, whereas CRISs would support the whole institutional research information management (RIM) with special emphasis on projects and funding. RIM being an activity oriented towards reporting for research assessment exercises and thus tightly connected to the institutional funding, the support from the Management at HEIs for CRIS implementation and operation and for the Research Office traditionally in charge of such tasks would be much higher than for the much less relevant IR. Moreover, the awareness of researchers and scholars towards such platforms will usually be much higher for the CRIS – from whose accurate and complete depiction of their research activity their salaries will ultimately depend – and it won’t be unusual to collect complaints on the need to ensure that both systems are simultaneously fed with the appropriate, often duplicated information. According to this conception, it is often hard to get the institutional Research Office and Library to work together for improving the end-user experience by enhancing their system interoperability. While much of this may still be happening at a number of HEIs, the general landscape is swiftly evolving and it's not that accurate anymore to describe the RIM system configuration at institutions in such oversimplified terms. CRIS/IR interoperability is now a fairly widespread feature that will allow both platforms to efficiently exchange information and reinforce each other's features, and especially the borders between what each of these platforms is and does are becoming increasingly blurred. Commercial CRISs are gradually becoming compliant with the OAI-PMH protocol and thus becoming able to offer institutions an integrated repository functionality, while the main open source IR platforms have now developed extended data models that will allow them to deliver features traditionally associated to CRISs such as project and funding management, hence becoming suitable solutions for research institutions where purchasing or developing a highly-sophisticated CRIS is not a top priority. This paper aims to describe the areas where CRIS/IR interoperability is taking place, and will provide a set of use cases for institutional research information system configuration involving IRs, CRISs and a combination of both. These will show how both systems are now increasingly merging for best serving institutions and their researchers.
