XML-packages received from Editorial Manager provide information about the "history" of the article. When was it received? When was it reviewed, accepted and published? Such information should be included in the XML-package, using the history-element. Including in the PDF is decided upon per journal. Within the history element,, multiple dates can be specified, using the attribute date-type to specify the meaning of the date-element. The following options for date-type are accepted (most frequently used are marked with a colored background):

value date-typemeaning
receivedDate that article was received
initial decisionDate that initial decision was taken on article
rev-requestThe date revisions were requested. There may be more than one @date-type with this value
rev-recdDate that a revised version of the article was received. There may be more than one @date-type with this value
acceptedDate that article was accepted in journal
pubThe publication date (online or print)
preprintPreprint dissemination date (online or print)
version-of-recordDate that the version of record of the article was published (online or print)
retractedThe date an article was retracted
correctedThe date an article was corrected

For articles that are not submitted through Editorial Manager, this information is in general not available. If provided in another way, the information can be included as well in the XML and - if applicable - PDF.
