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://0-psychoceramics.labs.crossref.org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/fundref.xsd"/>
<doi_data>
   <doi>10.5555/12345678</doi>
   <resource>http://0-psychoceramics.labs.crossref.org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/AccessIndicators.xsd"/>
<doi_data>
   <doi>10.5555/12345678</doi>
   <resource>http://0-psychoceramics.labs.crossref.org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/relations.xsd"/>
<doi_data>
   <doi>10.5555/12345678</doi>
   <resource>http://0-psychoceramics.labs.crossref.org.brum.beds.ac.uk/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://0-www-crossref-org.brum.beds.ac.uk/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://0-annalsofpsychoceramics.labs.crossref.org.brum.beds.ac.uk/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://0-psychoceramics.labs.crossref.org.brum.beds.ac.uk/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>
