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.
We’ve all been subject to floods of conference invitations, it can be difficult to sort the relevant from the not-relevant or (even worse) sketchy conferences competing for our attention. In 2017, DataCite and Crossref started a working group to investigate creating identifiers for conferences and projects. Identifiers describe and disambiguate, and applying identifiers to conference events will help build clear durable connections between scholarly events and scholarly literature.
Chaired by Aliaksandr Birukou, the Executive Editor for Computer Science at Springer Nature, the group has met regularly over the past two years, collaborating to create use cases and define metadata to identify and describe conference series and events. We first asked for input on metadata specifications in April 2018. Technical implementation kicked off in February with a workshop at CERN to discuss the mechanics of making PIDs for conferences a reality.
We’ve reached another milestone and want your feedback
Crossref has supported a number of conference publication-related PIDs for years - members can currently register PIDs for conference series publications, conference proceedings, and of course individual conference papers - and that won’t change, but we will also be supporting DOI registration for conferences. A crucial step towards this is of course integrating the new identifier into our metadata input schema.
The details
We currently collect some limited metadata describing the conference itself such as theme, location, and dates as part of the conference series or proceeding metadata, but do not apply a DOI to that information. The new Conference ID records will include expanded metadata as defined by the working group. You’ll be able to register a distinct metadata record for a single conference. You’ll also be able to register a record for a conference series, and connect Conference IDs to conference proceeding metadata records and DOIs.
Changes to the conference-specific metadata are backwards compatible. Members will be able to register event metadata per usual, or can instead use the new event metadata to register an identifier for their conference event and/or series. This means a member can:
Register conference, conference series, proceedings series, proceedings, and papers in one submission
Register proceedings or proceedings series and papers without a Conference ID included
Register Conference IDs only
Update an existing conference record with a Conference PID
I’ve written up our proposal in this google doc and we want your feedback before we proceed with implementation. Please comment directly in the Google doc, open a Gitlab issue, or feedback@crossref.org. We’ll keep the document open for comments until September 30.
