Measuring Metadata Impacts: Books Discoverability in Google Scholar

This blog post is from Lettie Conrad and Michelle Urberg, cross-posted from the The Scholarly Kitchen. As sponsors of this project, we at Crossref are excited to see this work shared out. The scholarly publishing community talks a LOT about metadata and the need for high-quality, interoperable, and machine-readable descriptors of the content we disseminate. However, as weā€™ve reflected on previously in the Kitchen, despite well-established information standards (e.g., persistent identifiers), our industry lacks a shared framework to measure the value and impact of the metadata we produce.

Introducing our new Global Equitable Membership (GEM) program

When Crossref began over 20 years ago, our members were primarily from the United States and Western Europe, but for several years our membership has been more global and diverse, growing to almost 18,000 organizations around the world, representing 148 countries. As we continue to grow, finding ways to help organizations participate in Crossref is an important part of our mission and approach. Our goal of creating the Research Nexus—a rich and reusable open network of relationships connecting research organizations, people, things, and actions; a scholarly record that the global community can build on forever, for the benefit of society—can only be achieved by ensuring that participation in Crossref is accessible to all.

How funding agencies can meet OSTP (and Open Science) guidance using existing open infrastructure

In August 2022, the United States Office of Science and Technology Policy (OSTP) issued a memo (PDF) on ensuring free, immediate, and equitable access to federally funded research (a.k.a. the ā€œNelson memoā€). Crossref is particularly interested in and relevant for the areas of this guidance that cover metadata and persistent identifiersā€”and the infrastructure and services that make them useful. Funding bodies worldwide are increasingly involved in research infrastructure for dissemination and discovery.

Better preprint metadata through community participation

Preprints have become an important tool for rapidly communicating and iterating on research outputs. There is now a range of preprint servers, some subject-specific, some based on a particular geographical area, and others linked to publishers or individual journals in addition to generalist platforms. In 2016 the Crossref schema started to support preprints and since then the number of metadata records has grown to around 16,000 new preprint DOIs per month.

Crossref Conversations: audio blog about helping open science

Rosa Clark

Rosa Clark, Anna Tolwinska – 2021 August 20

In Community

Crossref Conversations is an audio blog we’re trying out that will cover various topics important to our community. This conversation is between colleagues Anna Tolwinska and Rosa Morais Clark, discussing how we can make research happen faster, with fewer hurdles, and how Crossref can help. Our members have been asking us how Crossref can support open science, and we have a few insights to share. So we invite you to have a listen.

Some rip-RORing news for affiliation metadata

Ginny Hendricks

Ginny Hendricks, Rachael Lammey, Patricia Feeney – 2021 July 26

In AffiliationsSchemaRORMetadata

Weā€™ve just added to our input schema the ability to include affiliation information using ROR identifiers. Members who register content using XML can now include ROR IDs, and weā€™ll add the capability to our manual content registration form, participation reports, and metadata retrieval APIs in the near future. And we are inviting members to a Crossref/ROR webinar on 29th September at 3pm UTC. The background Weā€™ve been working on the Research Organization Registry (ROR) as a community initiative for the last few years.

RFP: Help evaluate the reach and effects of metadata

Jennifer Kemp

Jennifer Kemp – 2021 July 21

In MetadataCommunity

UPDATE, 14 October 2021: We received several excellent proposals in response to this RFP and weā€™d like to thank everyone involved for their time and enthusiasm. We are excited to announce the two projects that have been selected, to run through early 2023. Stay tuned! With or Without: Measuring Impacts of Books Metadata This project will test the premise that academic books metadata improves discoverability and usage by assessing the impact of book chapter records with DOIs (unique from metadata associated with the entire book) with associated chapter and book attributes.

Behind the scenes improvements to the REST API

Patrick Polischuk

Patrick Polischuk – 2021 July 06

In REST APICommunity

UPDATE, 24 August 2021: All pools have been migrated to the new Elasticsearch-backed API, which already appears to be more stable and performant than the outgoing Solr API. Please report any issues via our Crossref issue repository in Gitlab. UPDATE, 9 August 2021: The cutovers for the polite and Plus pools are delayed again. We’re still working to ensure acceptable performance and stability before serving responses from the new application and infrastructure.

DOAJ and Crossref sign agreement to remove barriers to scholarly publishing for all

In News ReleaseCollaborationDOAJCommunity

22 June 2021, London, UK and Boston, MA, USA ā€” The future of global open access publishing received a boost today with the signing of a Memorandum of Understanding between the Directory of Open Access Journals (DOAJ) and Crossref. The MOU formalizes an already strong partnership between the two organisations and furthers their shared pursuit of an open scholarly communications ecosystem that is inclusive of emerging publishing communities. Both organisations aim to encourage the dissemination and use of scholarly research using open infrastructure, online technologies, regional and international networks, and community partners - all supporting local institutional capacity and sustainability around the world.

Event Data: Help us fill in the gaps

In Event DataRequest for Proposal

UPDATE August 2, 2021: This work was awarded to Laura Paglione of the Spherical Cow Group. To date, we have collected around 740 million events from 12 different source since we launched our Event Data service service in 2017. Each event is an online mention of the research associated with a DOI, either via the DOI directly or using the associated URL. However, we know that there is much more out there.

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 ā€˜posted contentā€™ since 2016, and members currently register a total of around 17,000 new preprints metadata records each month.

Time to put the “R” back in “R&D”

Geoffrey Bilder

Geoffrey Bilder – 2021 June 07

In LabsR&D

It is time to put the ‘R’ back into R&D. The Crossref R&D team was originally created to focus on the kinds of research projects that have allowed Crossref to make transformational technology changes, launch innovative new services, and engage with entirely new constituencies. Some Illustrious projects that had their origins in the R&D group include: DOI Content Negotiation Similarity Check (originally CrossCheck) ORCID (originally Author DOIs) Crossmark The Open Funder Registry The Crossref REST API Linked Clinical Trials Event Data Grant registration ROR And for each project that has graduated, there have been several that have not.

The road ahead: our strategy through 2025

Ginny Hendricks

Ginny Hendricks – 2021 June 03

In Strategy

This announcement has been in the works for some time, but everything seems to take longer when there is a pandemic going on, including finding time and headspace to plan out our strategy for the next few years. Over the last year or so we have had our heads down addressing how to scale our 20-yr-old system and operation – and adapting to new ways of working. But we’ve also spent time talking to people, forging alliances, looking ahead, and making plans.
