To update your metadata records, simply re-submit your metadata record with the changes included. Be sure to supply the correct DOI in your submission to ensure we update the appropriate record. You may update your metadata records as often as needed. No fees are charged for updating existing metadata records.
Note that the value included in the timestamp element must be incremented each time a DOI is updated.
Updating bibliographic metadata
When making an update you must supply all the bibliographic metadata for the article, not just the fields that need to be changed. During the update process we overwrite the existing metadata with the new information you submit, and will insert null values for any fields not supplied in the update. This means, for example, that if you've supplied an online publication date in your initial deposit, you'll need to include that date in subsequent deposits if you wish to retain it.
Updating non-bibliographic metadata
Some pieces of metadata may be added or updated independently using a resource-only deposit. These includesfunding, license, Crossmark, relationship, and citation list metadata.
