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.
The depositor report is used for checking basic info about your DOI registrations.
Depositor reports list all DOIs by member and title for journals, books, and conference proceedings. We currently have depositor reports for journals, books, and conference proceedings (but not for other record types). The index page is updated weekly. Title-level reports are updated as your metadata is updated with us.
Each title-level report lists all DOIs registered for the title as well as (for each DOI) the owning prefix, the deposit timestamp, the date the record was last updated, and the number of Cited-by matches. To view each title-level report, select the member name then the appropriate title.
Field/missing metadata report: You can also see what basic bibliographic metadata fields are populated for your journal articles - click on the green triangle to the right of each member name to view a field / missing metadata report.
DOI crawler: We crawl a broad sample of journal DOIs to make sure the DOIs are resolving to the appropriate page. For each journal crawled, a sample of DOIs that equals 5% of the total DOIs for the journal up to a maximum of 50 DOIs is selected. You can access the crawler details for a given journal by selecting the linked date in the ‘last crawl date’ column.
Click on a member name in the report, and you will see a list of that member’s titles below the name. Click on any publication title to open a text file which list all DOIs for that title.
The initial view shows:
Name: name of the member. Members with more than one prefix will appear multiple times
Journal/Book/Conf Proc count: number of journal, book, or conference proceeding titles associated with the member
Total DOIs: total number of DOIs deposited for the selected title
Field report: shows missing metadata fields for each member, select the icon to view
The expanded view shows:
Name of each journal, book, or conference proceeding with DOI names deposited by the member
DOIs: Total number of DOIs registered for each journal, book, or conference proceeding deposited by the member
Last crawl date: date of last crawler report (if available)
Depositor report title view
Select a journal, book, or conference proceeding title to retrieve a list of DOIs for the title (DOI), the owner prefix of the DOI (OWNER), the timestamp value for the DOI (DEPOSIT-TIMESTAMP) the date the DOI was last updated (LAST-UPDATED), and the number of Cited-by matches for the DOI:
Title-level depositor report data may also be retrieved using format=doilist - learn more about retrieving DOIs by title.
