Meta-data not sharing thru iCloud z photo library

Having spent many hours over nearly 10 years adding names, places, albums, keywords etc to c50k photos and videos I am very disappointed that these are not included in the Shared Library functionality. Does this mean that the several hundred names, and all other identifying data, have to be re-entered again on my partners Mac? I see that it is going thru picking out faces to name but it is continuing to identify people incorrectly. This requiring a manual cleanse thru all the photos coupled with adding names to people not picked up on the scan. A lot of work.

Can the meta data be synced thru? This affects Mac, ipad and iPhone photo libraries.
