Your thoughts on book classification codes (BISAC subject headings) as tags?

[droopy]

What are the pros and cons for keeping the code portion of BISAC subject headings as tags?
An example of a BISAC subject heading is FIC022020 FICTION / Mystery & Detective / Police Procedural. What I call the "code portion" in this case is "FIC022020".

There are quite a number of tags in my library that have just the "code portion" (FIC022020) without the "human-understandable" portion (FICTION / Mystery & Detective / Police Procedural).

What are your thoughts on deleting these tags that are just the code portion?

There doesn't seem to be a plugin that can convert code-portion-only tags to the human-understandable subjects. (I checked https://plugins.calibre-ebook.com/).
If there were a way to quickly make such a conversion, that would enrich my tags.

I never go by any tags in the book's metadata. I just delete those tags from the OPF and from TAGS and I'm good to go. I can put in my own tags if I want or if it is a book in a series, the series info. I do not want the tags column clogged up with crap from the eBook that I did not put there. And a lot of it is crap.

I use only my own personal tags as well. All tags that come with books get bulk deleted after adding the books to the library. And I don't use metadata download either. I edit metadata manually. Yes, it takes days or even weeks, but I can be sure everything is exactly as I want.

I use a very limited set of tags that I apply myself. Tags that come with the book are removed. I use the individual metadata download which is set to not download tags. Personally, I can't understand the mania for adding so many tags to each book.

Fantasy fiction; American, Fiction, General, Imaginary places, Life on other planets, science fiction

Those are all the tags I ended up with from one book. Only one of them is useful. The rest is rubbish. This is why I delete the tags that are auto created from the mess in the OPF. I do so so I can put in what I want or nothing at all. If the book is part of a series, there usually is no tag. And i usually only put in one tag.

Whoever comes up with the tags has no clue.

Yeah, same here. Well, I only put in one tag for genre, but a couple of others for other things (which device the book is on, whether I want to read it soon or it can wait and so on).

Actually, the Job Spy plugin has Tag Scrubbing functionality that can easily do what you want. Simply create a .csv file in the appropriate from-to format, upload it to JS using its menu item for that purpose, and run the Tag Scrubbing menu items. The menu path is JS > Metadata Tools > Scrub Tag/Tag-Like columns using Rules Tables.
