I've worked with a vendor listing products in their IDM (Item Data Management) System. IIRC, it's from https://www.stibosystems.com/ . From a SMB vendor supplying one type of product it's frustrating to work with, with a lot of back and forth and workflows for verifying all manner of compliance with data quality, global regulations, and laws. From their internal perspective, it's probably the bee's knees, supporting a wide variety of taxonomies, considering the variety of products they sell & support, some rather dangerous and hazardous.

From looking over the shoulders of the staff, some aspects of the system that I've seen as a supplier are directly visible to them too.
