In case you wan to process a folder with many many imagine, you want to avoid using the filepatern node, i mean filter the item before and not after... Or did i miss something ?

I see... In my experience, what i just mean, is the way you have to think a full setup in TOP has some particularities that force me to do some change in my approach. And some more important than i was hoping at first and also more time consuming.

You could also output a log file in sop per frame, and with partition , you could eventually pair the association with the output...
After sorry i have never tried the python approach you picked here...

Why are you creating the detail attribute outside Top, and attach it as an item process attribute?
It will be more straightforward no?
I haven't use python in the TOP ropoverlay, maybe also you have different version of Python between your 2 differents versions?

When doing wedge and so, PDG is relatively simple. But try to have HDA with multiples output, and link output dependency with other brick later is really not that simple and intuitive at all, something you could play easily in SOP by accessing any attributes, in TOP just doesn't work that way. And you could ended with lot's of file or bad memory management too.
Try to creat the attribute in TOP before , and after in the top overlay just add something like:
Building Variation: `@Nameextract`
Building Family: `@Category`
