To date, we have collected around 740 million 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. Because of this, we would like to explore where we could expand.
We invite proposals to conduct a gap analysis for Event Data sources, looking at what we currently collect and seeing what more could be added.
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 ‘posted content’ since 2016, and members currently register a total of around 17,000 new preprints metadata records each month.
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.
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.
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 content 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.
