Flies in your metadata (ointment)

Quality metadata is foundational to the research nexus and all Crossref services. When inaccuracies creep in, these create problems that get compounded down the line. No wonder that reports of metadata errors from authors, members, and other metadata users are some of the most common messages we receive into the technical support team (we encourage you to continue to report these metadata errors). We make members’ metadata openly available via our APIs, which means people and machines can incorporate it into their research tools and services - thus, we all want it to be accurate.

How I think about ROR as infrastructure

The other day I was out and about and got into a conversation with someone who asked me about my doctoral work in English literature. I’ve had the same conversation many times: I tell someone (only if they ask!) that my dissertation was a history of the villanelle, and then they cheerfully admit that they don’t know what a villanelle is, and then I ask them if they’re familiar with Dylan Thomas’s poem “Do not go gentle into that good night.

Seeing your place in the Research Nexus

Having joined the Crossref team merely a week previously, the mid-year community update on June 14th was a fantastic opportunity to learn about the Research Nexus vision. We explored its building blocks and practical implementation steps within our reach, and within our imagination of the future. Read on (or watch the recording) for a whistlestop tour of everything – from what on Earth is Research Nexus, through to how it’s taking shape at Crossref, to how you are involved, and finally – to what concerns the community surrounding the vision and how we’re going to address that.

Announcing our new Head of Strategic Initiatives: Dominika Tkaczyk

TL;DR A year ago, we announced that we were putting the “R” back in R&D. That was when Rachael Lammey joined the R&D team as the Head of Strategic Initiatives. And now, with Rachael assuming the role of Product Director, I’m delighted to announce that Dominika Tkaczyk has agreed to take over Rachael’s role as the Head of Strategic Initiatives. Of course, you might already know her. We will also immediately start recruiting for a new Principal R&D Developer to work with Esha and Dominika on the R&D team.

An Advisory Group for Preprints

Martyn Rittman

Martyn Rittman – 2021 June 09

In PreprintsMetadataCommunityRelationships

We are delighted to announce the formation of a new Advisory Group to support us in improving preprint metadata. Preprints have grown in popularity over the last few years, with increasing focus brought by the need to rapidly disseminate knowledge in the midst of a global pandemic. We have supported metadata deposits for preprints under the content type ‘posted content’ since 2016, and members currently register a total of around 17,000 new preprints metadata records each month.

Using the Crossref REST API. Part 12 (with Europe PMC)

In APIsAPI Case StudyPreprints

As part of our blog series highlighting some of the tools and services that use our API, we asked Michael Parkin—Data Scientist at the European Bioinformatics Institute—a few questions about how Europe PMC uses our metadata where preprints are concerned.

Leaving the house - where preprints go

“Pre-prints” are sometimes neither Pre nor Print (c.f. https://doi.org/10.12688/f1000research.11408.1, but they do go on and get published in journals. While researchers may have different motivations for posting a preprint, such as establishing a record of priority or seeking rapid feedback, the primary motivation appears to be timely sharing of results prior to journal publication.

So where in fact do preprints get published?

Preprints growth rate ten times higher than journal articles

In PreprintsMetadataContent RegistrationCitation

The Crossref graph of the research enterprise is growing at an impressive rate of 2.5 million records a month - scholarly communications of all stripes and sizes. Preprints are one of the fastest growing types of content. While preprints may not be new, the growth may well be: ~30% for the past 2 years (compared to article growth of 2-3% for the same period). We began supporting preprints in November 2016 at the behest of our members. When members register them, we ensure that: links to these publications persist over time; they are connected to the full history of the shared research results; and the citation record is clear and up-to-date.

More metadata for machines-citations, relations, and preprints arrive in the REST API

In APIsCitationPreprintsNews Release

Over the past few months we have been adding to the metadata and functionality of our REST API, Crossref’s public machine interface for the metadata of all 90 million+ registered content items. Much of the work focused on a review and upgrade of the API’s code and architecture in order to better support its rapidly growing usage. But we have also extended the types of metadata that the API can deliver.

Included, registered, available: let the preprint linking commence.

In APIsLinkingMetadataPreprints

We began accepting preprints as a new content type last month (in a category known as “posted content” in our XML schema). Over 1,000 records have already been registered in the first few weeks since we launched the service.

By extending our existing services to preprints, we want to help make sure that:

  • links to these publications persist over time
  • they are connected to the full history of the shared research
  • the citation record is clear and up-to-date.

Preprints are go at Crossref!

In PersistencePreprints

We’re excited to say that we’ve finished the work on our infrastructure to allow members to register preprints. Want to know why we’re doing this? Jennifer Lin explains the rationale in detail in an earlier post, but in short we want to help make sure that:

  • links to these publications persist over time
  • they are connected to the full history of the shared research results
  • the citation record is clear and up-to-date

Doing so will help fully integrate preprint publications into the formal scholarly record.

Preprints and Crossref’s metadata services

In Preprints

We’re putting the final touches on the changes that will allow preprint publishers to register their metadata with Crossref and assign DOIs. These changes support Crossref’s CitedBy linking between the preprint and other scholarly publications (journal articles, books, conference proceedings). Full preprint support will be released over the next few weeks.

Getting ready to run with preprints, any day now

In Content RegistrationPreprints

While preprints have been a formal part of scholarly communications for decades in certain communities, they have not been fully adopted to date across most disciplines or systems. That may be changing very soon and quite rapidly, as new initiatives come thick and fast from researchers, funders, and publishers alike. This flurry of activity points to the realization from these parties of preprints’ potential benefits: Accelerating the sharing of results; Catalyzing research discovery; Establishing priority of discoveries and ideas; Facilitating career advancement; and Improving the culture of communication within the scholarly community.

Hello preprints, what’s your story?

Jennifer Lin

Jennifer Lin – 2016 June 23

In Content RegistrationPreprints

The role of preprints Crossref provides infrastructure services and therefore we support scholarly communications as it evolves over time. Today, preprints are increasingly discussed as a valuable part of the research story (beyond physics, math, and a small set of sub-disciplines). Preprints might play a positive role in catalyzing research discovery, establishing priority of discoveries and ideas, facilitating career advancement, and improving the culture of communication within the scholarly community. As we shared in an earlier blog post last month, members will be able to register Crossref DOIs for preprints later this year.
