In the first half of this year we’ve been talking to our community about post-publication changes and Crossmark. When a piece of research is published it isn’t the end of the journey—it is read, reused, and sometimes modified. That’s why we run Crossmark, as a way to provide notifications of important changes to research made after publication. Readers can see if the resesarch they are looking at has updates by clicking the Crossmark logo.
We’re happy to note that this month, we are marking five years since Crossref launched its Grant Linking System. The Grant Linking System (GLS) started life as a joint community effort to create ‘grant identifiers’ and support the needs of funders in the scholarly communications infrastructure.
The system includes a funder-designed metadata schema and a unique link for each award which enables connections with millions of research outputs, better reporting on the research and outcomes of funding, and a contribution to open science infrastructure.
In our previous blog post about metadata matching, we discussed what it is and why we need it (tl;dr: to discover more relationships within the scholarly record). Here, we will describe some basic matching-related terminology and the components of a matching process. We will also pose some typical product questions to consider when developing or integrating matching solutions.
Basic terminology Metadata matching is a high-level concept, with many different problems falling into this category.
Update 2024-07-01: This post is based on an interview with Euan Adie, founder and director of Overton._
What is Overton? Overton is a big database of government policy documents, also including sources like intergovernmental organizations, think tanks, and big NGOs and in general anyone who’s trying to influence a government policy maker. What we’re interested in is basically, taking all the good parts of the scholarly record and applying some of that to the policy world.
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.
