The trackinghistory element contains information used to track production of the XML file. e.g. dates at which it was created, edited, published online etc. These dates are intended for internal tracking use and are not generally displayed. Whenever a significant process has been carried out on an XML file, a trackingdate element should be added to trackinghistory. An example trackinghistory is shown below:
<trackinghistory> <trackingdate type="markedup" date="2000-06-15" by="John Brown" software="BEES" version="2.37"/> <trackingdate type="paginated" date="2000-09-12" by="Typesetters Ltd"/> <trackingdate type="received" date="2000-05-17"/> <trackingdate type="revised" date="2000-08-07"/> <trackingdate type="accepted" date="2000-08-09"/> </trackinghistory>
The history element is specifically for editorial tracking information relating usually to journal articles which is displayed in print and online. For example, the last line of the following footnote group from a journal article:

would be tagged as follows:
<footnotegroup> ... <history><p>(Received 17 May 2000, revised 7 August 2000, accepted 9 August 2000)</p></history> </footnotegroup>
