We defined a taxonomy of our 40000+ products already. We have a change process and actively manage this taxonomy in a spreadsheet. Can we reuse it in AEM and DAM?
@richardp6488432 Metadata Import/Export via CSV is standard feature in AEM Assets. See these videos: https://experienceleague.adobe.com/docs/experience-manager-learn/assets/metadata/metadata-import-fea...
In ACS AEM Commons , there is a Tags to CSV exporter. http://localhost:4502/etc/acs-commons/exporters/tag-to-csv-exporter.html I am not sure if there is any OOTB tool for CSV to Tag Importing. What best you can do is to write a custom import tool depending on your use cases.
