<p><font size="2" face="sans-serif">Hi,</font><br>
<br>
<font size="2" face="sans-serif">and a happy and successful 2016!</font><br>
<br>
<font size="2" face="sans-serif">If one wants to find all eprints for which a given field X has changed its value from A to B, this seems to be quite cumbersome, because the history table only stores the name of the fields that have been modified, but not their content, which is saved in the revisions XML files in the documents directory.</font><br>
<br>
<font size="2" face="sans-serif">- Is there already a method or script that enables one to do so?</font><br>
<font size="2" face="sans-serif">- Why has this been designed this way, and not the way that all changes (which field and which content) are tracked in the SQL database? Whether disk space is used up by the database or in the filesystem should not matter. Having the changes only in the database would facilitate searching a lot; in addition, rollbacks to a given point would be possible.</font><br>
<br>
<font size="2" face="sans-serif">Best regards,</font><br>
