Such dates are generated by other data archives and reflected after data exchange with other International Nucleotide Sequence Database Collaboration (INSDC) data archives.
   
  -== Common questions
  -
  -=== What was changed on the update date?
  -
  -To check what has been updated in the latest update, please check the https://www.ebi.ac.uk/biosamples/docs/guides/curation[curation documenation].
  -
  -=== Why is the sample “ID created on” date different from the “Submitted on” date?
  -Sample accessions may be generated well in advance of sample metadata submission, for example when samples are pre-registered. The creation date indicates the date at which an ID was created in the database.
  -
  -=== My sample doesn’t have a "Submitted on" date?
  -The Submitted on date field was added in our release in November 2020. All samples submitted after November 17th 2020 will present this information. Older samples may not have that date - this will be progressively added as our curation pipelines periodically run, or can be added on request at biosamples <at> ebi.ac.uk.
