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!

Documentation

UNIXSD query output format

UNIXSD query results include member metadata as deposited (as with the UNIXREF format) as well as some Crossref-generated information about the metadata record. UNIXSD is the most comprehensive metadata output format available for our metadata records.

UNIXSD format will return deposited references for other members. References will also be returned to members querying for their own deposited data.

UNIXSD metadata

UNIXSD results contain a sequence of Crossref produced meta-metadata including:

  • book-id: a Crossref internal identifier assigned to a non-journal title (book, conference proceeding, database, standard, dissertation, or report/working paper)
  • citation-id: a Crossref internal identifier assigned to a DOI record
  • citedby-count: number of Cited-by matches identified by Crossref
  • created: the date the record was created
  • deposit-timestamp: timestamp provided in most recent submission
  • journal-id: a Crossref internal identifier assigned to a journal title
  • last-update: the date the record was last updated
  • member-id: a Crossref internal identifier assigned to a member
  • owner-prefix: the prefix that ‘owns’ (has permissions to update) the DOI record
  • prefix-name: name associated with the prefix
  • prime: the DOI a record is aliased to (if the record is aliased)
  • publisher-name: member account name
  • relation: related item, includes ‘type’ attribute to identify the identifier, and ‘claim’ to identify type of relationship
  • series-id: a Crossref internal identifier assigned to a series title (applies to book and conference proceeding series)

This meta-metadata is contained in a <crm-item> element, for example:

<crm-item name="citedby-count" type="number">0</crm-item>
<crm-item name="owner-prefix" type="string">10.1353</crm-item>
<crm-item name="citation-id" type="number">25715607</crm-item>
<crm-item name="journal-id" type="number">48965</crm-item>
<crm-item name="book-id" type="number" />
<crm-item name="series-id" type="number" />
<crm-item name="last-update" type="date">2007-08-07 15:31:43.0</crm-item>

The full metadata record as deposited by members is available as well. The member as-deposited XML will begin with the <crossref> element.

UNIXSD schema

UNIXSD results are generated using crossref_query_output3.0.xsd (schema | documentation)
