@kovid,
thanks for your answer. Exactly that answer I have feared, but I thought it's better to ask first
You are right, it is more a special case.
@theducks,
Yes I have. Unfortunately I have a lot of custom columns. It is a more ergonomically issue to take care that informations have a specific order for manual input. I can't change the source for that kind of data.
@BetterRed, thanks for this suggestion. As I do not use this PI I need to take a look on it first. Last time I took a look on it is long time ago. I haven't a issue with presentation/sorting metadata in the book list view, that is manageable for me. It is more a problem of input the data in a economic way without searching and jumping into fields in an input mask if I have different library setups. The list view is for me not a good tool for input a huge amount of metadata.
Anyway. My guess is, that I need to find an other and better solution for my special case. I am on the way doing this. The good thing is that most of that data are listed in the extended file properties. The worse thing is, that I am not able to get them out with power shell right now. As soon I have manage that, I will do the whole stuff with CLI, what at the end is hopefully a much better solution for what I like to do.
Thanks for your input.
