I am trying to update the metadata of an article that has been corrected. As far as I know, OJS will not generate an XML with this information. Therefore, following the examples available in Crossref Website, I tried to edit the regular XML of the article to include the information about the correction.
However, I get the following error:
Error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'crossmark'. One of '{"http://0-www-crossref-org.library.alliant.edu/relations.xsd":program, "http://0-www-crossref-org.library.alliant.edu/schema/4.3.6":archive_locations, "http://0-www-crossref-org.library.alliant.edu/schema/4.3.6":doi_data}' is expected.
The links mentioned in the error message lead to “not found pages” (404 error).
What I did was to include the following code before the <doi_data> tag, just like in the above mentioned examples:
Thanks for your message, and welcome to the community forum. Do you happen to have the submission ID from our system that generated this error message? I’d like to review the entire submission in our admin tool to provide you with guidance on a fix.
After posting the message I realized that the original XML submitted didn’t have any crossmark content, and I wondered if this could be the cause of the problem, since now I am trying to make an update.
Ah. Yes. This is because the timestamp has not been increased in your follow-up submission.
The error message ‘Record not processed because submitted version: ___ is less or equal to previously submitted version (DOI match)’ indicates that the timestamp in your deposit is numerically lower than the timestamp used in a previous deposit.
Every deposit has a value, and that value needs to be incremented each time the DOI is updated. The timestamp errors do indicate that the DOI has been deposited, so if the metadata and URLs previously deposited for the DOIs are correct no further action is needed. You can find the most recent timestamp by reviewing your past deposit XML. Timestamps are also listed in the depositor reports available here: crossref.org : : depositor
