Metadata removal markup guide
For most metadata elements, you can just update the record to delete elements. However, if you are sending us XML, there are some non-bibliographic metadata elements where you have to go through a two-stage process - firstly send us a submission to delete this element, and then send us a further submission to add in the replacement data.
Metadata that needs to be explicitly deleted includes:
You can also delete non-bibliographic metadata by supplying an empty parent element (see examples below), and include it in a metadata update or submit it as a resource-only deposit. Note that metadata submitted as part of a Crossmark update needs to be removed within Crossmark metadata (see examples below).
Remove all Crossmark data
Remove all Crossmark data from a record by supplying an empty Crossmark element in a metadata deposit:
<first_page>1</first_page>
<last_page>3</last_page>
</pages>
<crossmark/>
<doi_data>
<doi>10.5555/12345678</doi>
<resource>http://psychoceramics.labs.crossref.org/10.5555-12345678.html</resource>
</doi_data>
or as part of a resource-only deposit:
<crossmark_data>
<doi>10.5555/12345678</doi>
<crossmark/>
</crossmark_data>
Remove funding, clinical trial, or license data from Crossmark
Funding, license, and clinical trial data may all be supplied as part of a Crossmark update. If you need to remove funding, license, or clinical trial metadata from your Crossmark metadata, you must submit the appropriate empty element within a Crossmark update. Note the other Crossmark metadata must be present as well to be retained.
In this example, funding data is removed from a Crossmark update:
<crossmark>
<crossmark_version>1</crossmark_version>
<crossmark_policy>10.5555/crossmark_policy</crossmark_policy>
<crossmark_domains>
<crossmark_domain>
<domain>psychoceramics.labs.crossref.org</domain>
</crossmark_domain>
</crossmark_domains>
<crossmark_domain_exclusive>true</crossmark_domain_exclusive>

Remove funding data
Remove funding data from a non-Crossmark record by supplying an empty fundref program element in a metadata deposit:
<first_page>1</first_page>
<last_page>3</last_page>
</pages>
<program xmlns="https://www.crossref.org/fundref.xsd"/>
<doi_data>
<doi>10.5555/12345678</doi>
<resource>http://psychoceramics.labs.crossref.org/10.5555-12345678.html</resource>
</doi_data>
or as part of a resource-only deposit:
<fundref_data>
<doi>10.5555/12345678</doi>
<program xmlns="https://www.crossref.org/fundref.xsd"/>
</fundref_data>
Remove license data
Remove license data from a non-Crossmark record by supplying an empty AccessIndicators program element in a metadata deposit:
<first_page>1</first_page>
<last_page>3</last_page>
</pages>
<program xmlns="https://www.crossref.org/AccessIndicators.xsd"/>
<doi_data>
<doi>10.5555/12345678</doi>
<resource>http://psychoceramics.labs.crossref.org/10.5555-12345678.html</resource>
</doi_data>
or as part of a resource-only deposit:
<lic_ref_data>
<doi>10.5555/12345678</doi>
<program xmlns="https://www.crossref.org/AccessIndicators.xsd"/>
</lic_ref_data>
Remove relationship data
Remove relationship data by supplying an empty relationship program element in a metadata deposit:
<first_page>1</first_page>
<last_page>3</last_page>
</pages>
<program xmlns="https://www.crossref.org/relations.xsd"/>
<doi_data>
<doi>10.5555/12345678</doi>
<resource>http://psychoceramics.labs.crossref.org/10.5555-12345678.html</resource>
</doi_data>
or as part of a resource-only deposit:
<doi_relations>
<doi>10.5555/12345678</doi>
<program xmlns="https://www.crossref.org/relations.xsd"/>
</doi_relations>
Remove text and data mining, Similarity Check, and multiple resolution URLs
Text and data mining and multiple resolution secondary URLs may be removed from a record by submitting an update containing an empty collection tag that includes the appropriate property:
- Text and data mining uses property
text-mining - Similarity Check URLs use the property
crawler-based - Multiple resolution secondary URLs use the property
list-based - The country-code resolution feature uses the property
country-based
For example, to remove text and data mining URLs from a record submit the following as part of a metadata deposit:
<doi_data>
<doi>10.5555/515151</doi>
<resource>http://annalsofpsychoceramics.labs.crossref.org/abstract/515151/</resource>
<collection property="text-mining"/>
</doi_data>
They may be included in a metadata deposit (above) or as part of a resource-only deposit:
<doi_resources>
<doi>10.5555/515151</doi>
<collection property="text-mining"/>
</doi_resources>
Remove references
Remove a reference list from a record by supplying an empty citation_list element in a metadata deposit:
<first_page>1</first_page>
<last_page>3</last_page>
</pages>
<doi_data>
<doi>10.5555/12345678</doi>
<resource>http://psychoceramics.labs.crossref.org/10.5555-12345678.html</resource>
</doi_data>
<citation_list/>
or as part of a resource-only deposit:
<doi_citations>
<doi>10.5555/12345678</doi>
<citation_list/>
</doi_citations>
