The GEM program - year one

In January 2023, we began our Global Equitable Membership (GEM) Program to provide greater membership equitability and accessibility to organisations located in the least economically advantaged countries in the world. Eligibility for the program is based on a member’s country; our list of countries is predominantly based on the International Development Association (IDA). Eligible members pay no membership or content registration fees. The list undergoes periodic reviews, as countries may be added or removed over time as economic situations change.

Increasing Crossref Data Reusability With Format Experiments

Every year, Crossref releases a full public data file of all of our metadata. This is partly a commitment to POSI and partly just what we do. We want the community to re-use our metadata and to find interesting ends to which they can be put! However, we have also recognized, for some time, that 170GB of compressed .tar.gz files, spread over 27,000 items, is not the easiest of formats with which to work.

I4OA Hall of Fame - 2023 edition

The Initiative for Open Abstracts (I4OA) was launched in September 2020 to advocate and promote the unrestricted availability of the abstracts of the world’s scholarly publications, particularly journal articles and book chapters, in trusted repositories where they are open and machine-accessible. I4OA calls on all scholarly publishers to open the abstracts of their published works and, where possible, to submit them to Crossref.

Discovering relationships between preprints and journal articles

In the scholarly communications environment, the evolution of a journal article can be traced by the relationships it has with its preprints. Those preprint–journal article relationships are an important component of the research nexus. Some of those relationships are provided by Crossref members (including publishers, universities, research groups, funders, etc.) when they deposit metadata with Crossref, but we know that a significant number of them are missing. To fill this gap, we developed a new automated strategy for discovering relationships between preprints and journal articles and applied it to all the preprints in the Crossref database. We made the resulting dataset, containing both publisher-asserted and automatically discovered relationships, publicly available for anyone to analyse.

Documentation

XML API

The XML API supports XML-formatted querying. XML queries give you significant control over the DOI matching process. The XML API is designed to (typically) return only one DOI, the one that best fits the metadata supplied in the query, and is therefore suitable for automated matching. Query results are returned in XML, and will contain a full or abbreviated metadata record for matched items, depending on the request. The query input schema file is crossref_query_input2.0.xsd - learn more in our schema documentation.

The XML API also supports DOI-to-metadata queries.
