SFX Routine Maintenance

SFX provides a tool for composing local thresholds. However, this works only when holdings are continuous. Split holding thresholds must be written manually with a “||” to separate the runs. For holdings from 1999-2002 and 2008, for example, the script would look like this:

$obj→parsedDate('>=','1999',undef,undef) && $obj→parsedDate('⇐','2002',undef,undef) || $obj→parsedDate('==','2008',undef,undef)

What displays is “Available from 1999 until 2002, Available in 2008”.
