In June 2022, we wrote a blog post “Rethinking staff travel, meetings, and events” outlining our new approach to staff travel, meetings, and events with the goal of not going back to ‘normal’ after the pandemic. We took into account three key areas:
The environment and climate change Inclusion Work/life balance We are aware that many of our members are also interested in minimizing their impacts on the environment, and we are overdue for an update on meeting our own commitments, so here goes our summary for the year 2023!
Metadata is one of the most important tools needed to communicate with each other about science and scholarship. It tells the story of research that travels throughout systems and subjects and even to future generations. We have metadata for organising and describing content, metadata for provenance and ownership information, and metadata is increasingly used as signals of trust.
Following our panel discussion on the same subject at the ALPSP University Press Redux conference in May 2024, in this post we explore the idea that metadata, once considered important mostly for discoverability, is now a vital element used for evidence and the integrity of the scholarly record.
For the third year in a row, Crossref hosted a roundtable on research integrity prior to the Frankfurt book fair. This year the event looked at Crossmark, our tool to display retractions and other post-publication updates to readers.
Since the start of 2024, we have been carrying out a consultation on Crossmark, gathering feedback and input from a range of members. The roundtable discussion was a chance to check and refine some of the conclusions we’ve come to, and gather more suggestions on the way forward.

In our previous blog post in this series, we explained why no metadata matching strategy can return perfect results. Thankfully, however, this does not mean that it’s impossible to know anything about the quality of matching. Indeed, we can (and should!) measure how close (or far) we are from achieving perfection with our matching. Read on to learn how this can be done!
How about we start with a quiz?
Funding metadata must include the name of the funding organization and the funder identifier (where the funding organization is listed in the Registry), and should include an award/grant number or grant identifier. Funder names should only be deposited without the accompanying ID if the funder is not found in the Registry. While members can deposit the funder name without the identifier, those records will not be considered valid until such a time as the funder is added to the database and they are redeposited (updated) with an ID. What that means is that they will not be found using the filters on funding information that we support via our REST API, or show up in our Open Funder Registry search.
Correct nesting of funder names and identifiers is essential as it significantly impacts how funders, funder identifiers, and award numbers are related to each other.
The purpose of funder groups is to establish relationships between funders and award numbers. A funder group assertion should only be used to associate funder names and identifiers with award numbers when multiple funders are present.
Funding data deposit with one group of funders (no “fundgroup” needed):
Funding data deposit with two fundgroups:
Incorrect: Groups used to associate funder names with funder identifiers, these need to be nested as described above.
Deposits using a funder_identifier that is not taken from the Open Funder Registry will be rejected.
Deposits with only funder_name (no funder_identifier) will not appear in funder search results in Open Funder Registry search or the REST API.
The <fr:program> element in the deposit schema section (see documentation) supports the import of the fundref.xsd schema (see documentation). The fundref namespace (xmlns:fr=https://0-www-crossref-org.libus.csd.mu.edu/fundref.xsd) must be included in the schema declaration, for example:
To accommodate integration with Crossmark, the fundref.xsd consists of a series of nested <fr:assertion> tags with enumerated name attributes. The name attributes are:
fundgroup: used to group a funder and its associated award number(s) for items with multiple funders.
funder_name: name of the funding agency as it appears in the funding Registry. Funder names that do not match those in the registry will be accepted to cover instances where the funding organization is not listed.
funder_identifier: funding agency identifier in the form of a DOI, must be nested within the funder_name assertion. The funder_identifier must be taken from the funding Registry and cannot be created by the member. Deposits without funder_identifier do not qualify as funding records.
award_number: grant number or other fund identifier
funder_nameandfunder_identifier must be present in a deposit where the funding body is listed in the Open Funder Registry. Multiple funder_name, funder_identifier, and award_number assertions may be included.
A relationship between funder_identifier and funder_name is established by nesting funder_identifier within funder_name. For example, this deposit has the funder National Science Foundation with its corresponding funder identifier in the Open Funder Registry of https://0-doi-org.libus.csd.mu.edu/10.13039/100000001 :
<fr:assertion name="funder_name">National Science Foundation
<fr:assertion name="funder_identifier">https://0-doi-org.libus.csd.mu.edu/10.13039/100000001</fr:assertion>
</fr:assertion>
A relationship between a single funder_name and/or funder_identifier and an award_number is established by including assertions with a <fr:program>. In this example, funder National Institute on Drug Abuse with funder identifier https://0-doi-org.libus.csd.mu.edu/10.13039/100000026 are associated with award number JQY0937263:
<fr:program name="fundref">
<fr:assertion name="funder_name">National Institute on Drug Abuse
<fr:assertion name="funder_identifier">https://0-doi-org.libus.csd.mu.edu/10.13039/100000026</fr:assertion>
</fr:assertion>
<fr:assertion name="award_number">JQY0937263</fr:assertion>
</fr:program>
If multiple funder and award combinations exist, each combination should be deposited within a fundgroup to ensure that the award number is associated with the appropriate funder(s). In this example, two funding groups exist:
<fr:program name="fundref">
<fr:assertion name="fundgroup">
<fr:assertion name="funder_name">National Science Foundation
<fr:assertion name="funder_identifier">https://0-doi-org.libus.csd.mu.edu/10.13039/100000001</fr:assertion>
</fr:assertion>
<fr:assertion name="award_number">CBET-106</fr:assertion>
<fr:assertion name="award_number">CBET-7259</fr:assertion>
</fr:assertion>
<fr:assertion name="fundgroup">
<fr:assertion name="funder_name">Basic Energy Sciences, Office of Science, U.S. Department of Energy
<fr:assertion name="funder_identifier">https://0-doi-org.libus.csd.mu.edu/10.13039/100006151</fr:assertion>
</fr:assertion>
<fr:assertion name="award_number">1245-ABDS</fr:assertion>
</fr:assertion>
</fr:program>
Items with multiple funder names but no award numbers may be deposited without a fundgroup.
At a minimum, a funding data deposit must contain a funder_name and funder_identifier assertion. Deposits with just an award_number assertion are not allowed. A funder_name, funder_identifier, and award_number should be included in deposits whenever possible.
If the funder name cannot be matched in the Registry, you may submit funder_name only, and the funding body will be reviewed and considered for addition to the official Registry. Until it is added to the Registry, the deposit will not be considered a valid funding record and will not appear in funding search or the REST API.
As demonstrated in Example 3 below, items with several award numbers associated with a single funding organization should be grouped together by enclosing the funder_name, funder_identifier, and award_number(s) within a fundgroup assertion.
Some rules will be enforced by the deposit logic, including:
Nesting of the<fr:assertion>elements: the schema allows infinite nesting of the assertion element to accommodate nesting of an element within itself. Deposit code will only allow 3 levels of nesting (with attribute values of fundgroup, funder_name, and funder_identifier)
Values of different<fr:assertion>elements: funder_name, funder_identifier, and award_number may have deposit rules imposed
Only valid funder identifiers will be accepted: the funder_identifier value will be compared against the Open Funder Registry file. If the funder_identifier is not found, the deposit will be rejected.
If funding metadata is incorrect or out-of-date, it may be updated by redepositing the metadata. Be sure to redeposit all available metadata for an item, not just the elements being updated. A DOI may be updated without resubmitting funding metadata, as previously deposited funding metadata will remain associated with the DOI.
Funding metadata may be deleted by redepositing an item with an empty <fr:program name="fundref"> element:
Submitting an empty Crossmark tag (<crossmark />) will delete all Crossmark data, including funding data. To delete only funding data, submit an empty <fr:program name="fundref"/> element:
Example 2: Funder information outside of Crossmark ``
The <fr:program> element captures funding data. It should be placed before the <doi_data> element. This deposit contains minimal funding data - one funder_name or one funder_identifier must be present; both are recommended.
<fr:program name="fundref">
<fr:assertion name="funder_name">National Science Foundation
<fr:assertion name="funder_identifier">https://0-doi-org.libus.csd.mu.edu/10.13039/100000001</fr:assertion> </fr:assertion>
</fr:program>
This example contains one funder_name and one funder_identifier. Note that the funder_identifier is nested within the funder_name assertion, establishing https://0-doi-org.libus.csd.mu.edu/10.13039.100000001 as the funder identifier for funder name National Science Foundation. Two award numbers are present.
