This year, metadata development is one of our key priorities and we’re making a start with the release of version 5.4.0 of our input schema with some long-awaited changes. This is the first in what will be a series of metadata schema updates.
What is in this update?
Publication typing for citations
This is fairly simple; we’ve added a ‘type’ attribute to the citations members supply. This means you can identify a journal article citation as a journal article, but more importantly, you can identify a dataset, software, blog post, or other citation that may not have an identifier assigned to it. This makes it easier for the many thousands of metadata users to connect these citations to identifiers. We know many publishers, particularly journal publishers, do collect this information already and will consider making this change to deposit citation types with their records.
Every year we release metadata for the full corpus of records registered with us, which can be downloaded for free in a single compressed file. This is one way in which we fulfil our mission to make metadata freely and widely available. By including the metadata of over 165 million research outputs from over 20,000 members worldwide and making them available in a standard format, we streamline access to metadata about scholarly objects such as journal articles, books, conference papers, preprints, research grants, standards, datasets, reports, blogs, and more.
Today, we’re delighted to let you know that Crossref members can now use ROR IDs to identify funders in any place where you currently use Funder IDs in your metadata. Funder IDs remain available, but this change allows publishers, service providers, and funders to streamline workflows and introduce efficiencies by using a single open identifier for both researcher affiliations and funding organizations.
As you probably know, the Research Organization Registry (ROR) is a global, community-led, carefully curated registry of open persistent identifiers for research organisations, including funding organisations. It’s a joint initiative led by the California Digital Library, Datacite and Crossref launched in 2019 that fulfills the long-standing need for an open organisation identifier.
We began our Global Equitable Membership (GEM) Program to provide greater membership equitability and accessibility to organizations in the world’s least economically advantaged countries. 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.
More and better license information is at the top of a lot of Christmas lists from a lot of research institutions and others who regularly use Crossref metadata. I know, I normally just ask for socks too. To help explain what we mean by this, we’ve collaborated with Jisc to set out some guidance for publishers on registering this license metadata with us.
At the most basic level, complete and accurate license metadata helps anyone interested in using a research work out how they can do so. Making the information machine-readable helps this to be done easily and at scale by all kinds of tools and services.
In this best practice guide, we’re specifically focusing on a use case for license metadata that comes from research institutions. They need to know which version of an article (or other content item) may be exposed in an open repository, and from what date, and tell anyone who comes across the piece of content in the repository what they can do with it once they find it there.
Without this being stated simply and clearly in the Crossref metadata, the institution won’t know which works they can make available and which they cannot, even if you as the publisher know that the item is open access, or is open access after a certain date. This can impact the research community’s capacity to find and use the research you publish.
The guidance offers advice on:
the kind of license information it’s useful to link out to from the Crossref metadata
what the Crossref metadata might look like for:
gold open access content
green open access content with a Creative Commons License
green open access content with a publisher-defined post-embargo license
how to add this metadata to existing or new Crossref deposits
Maybe there’s more to the story than this, or more information that you need as a publisher or as a research institution - if so, let us know and we can adapt this document based on your feedback. Requests for socks may be declined.
