A progress update and a renewed commitment to community

Looking back over 2024, we wanted to reflect on where we are in meeting our goals, and report on the progress and plans that affect you - our community of 21,000 organisational members as well as the vast number of research initiatives and scientific bodies that rely on Crossref metadata. In this post, we will give an update on our roadmap, including what is completed, underway, and up next, and a bit about what’s paused and why.

A summary of our Annual Meeting

The Crossref2024 annual meeting gathered our community for a packed agenda of updates, demos, and lively discussions on advancing our shared goals. The day was filled with insights and energy, from practical demos of Crossref’s latest API features to community reflections on the Research Nexus initiative and the Board elections. Our Board elections are always the focal point of the Annual Meeting. We want to start reflecting on the day by congratulating our newly elected board members: Katharina Rieck from Austrian Science Fund (FWF), Lisa Schiff from California Digital Library, Aaron Wood from American Psychological Association, and Amanda Ward from Taylor and Francis, who will officially join (and re-join) in January 2025.

2024 POSI audit

Background The Principles of Open Scholarly Infrastructure (POSI) provides a set of guidelines for operating open infrastructure in service to the scholarly community. It sets out 16 points to ensure that the infrastructure on which the scholarly and research communities rely is openly governed, sustainable, and replicable. Each POSI adopter regularly reviews progress, conducts periodic audits, and self-reports how they’re working towards each of the principles. In 2020, Crossref’s board voted to adopt the Principles of Open Scholarly Infrastructure, and we completed our first self-audit.

Summary of the environmental impact of Crossref

In June 2022, we wrote a blog post “Rethinking staff travel, meetings, and events” outlining our new approach to staff travel, meetings, and events with the goal of not going back to ‘normal’ after the pandemic. We took into account three key areas: The environment and climate change Inclusion Work/life balance We are aware that many of our members are also interested in minimizing their impacts on the environment, and we are overdue for an update on meeting our own commitments, so here goes our summary for the year 2023!

Crossref Public Data File

You have an alternative to the REST API if your goal is to obtain the entire body of Crossref’s records. With the public data file you have access to every DOI ever registered with Crossref.

2024 Public data file

Tips for working with Crossref public data files and Plus snapshots

Important considerations:

  • The records are in JSON.
  • Metadata is supplied by our members and, as such, not all records have the same completeness or quality of metadata.
  • Every year our metadata corpus grows. The first data file was 65GB and held 112 million records; this year the file weighs in at 212 GB and contains metadata for 156 million records, or all Crossref records registered up to and including April 2024.
  • Decompressing the .tar.gz files will take you several hours.

Additional convenient tools:

Given the size and the amount of files that the public data files comprises, we started experimenting with some additional tools to improve access to the data and repack the data into additional formats:

These tools are experimental, so please remember that we they are released without warranties and support, but are happy to hear about your experience using them. You can read more about them in this blog post
