Create a task that orders the 6xx (subject) fields
Alma currently does not have a way to mass resequence the 6xx subject fields, at least into consecutive order. This is an issue in analytics if subject is the field you organize your results by, as the initial subject field (600) may no longer be the first subject displayed and therefore searched on.
Alma now supports XSL normalization rules, enhancing its capabilities beyond the existing DROOLS-based rules. This new functionality enables more advanced and sophisticated data normalization processes.
A blog post has been published demonstrating how to use an XSL normalization process to address the request described in this idea. You can read it here: https://developers.exlibrisgroup.com/blog/how-to-re-sequence-all-marc-fields-using-xsl-normalization/
