Thoughts for metadata?

Hi fellow Calibre users

I have now accumulated numerous (700 or so) books in my calibre library, and when I was checking my tags I realized that they are all over the place.

I am mainly interested in the TAG one, and don't wanting like 20 different Science Fiction tags with different categories added to it.

For me, I was thinking of only using some main categories like
Fiction, Fantasy, Science Fiction, AutoBiography, Alternate History, History, Supernatural

And some extra, like short stories, space opera

Is there a tool that can be used to for every book grab key categories on the web for instance to help ensuring I get the proper key categories.

Which categories do you all otherwise use?

That looks like a task for a new plugin

The main problem for such requirements is probably that in Calibre it is difficult to map complex taxonomies. CMS like Drupal or Wordpress distinguish between "categories" and "tags". Categories can have hierarchies, labels cannot.
Hierarchies can only be mapped in Calibre in series (main series.sub-series ...).

The second problem is that the appropriate pool of keywords is mostly genre-dependent. One would therefore have to define one or more suitable sources for each genre. For SF this could be For this database I maintain a metadata plugin (ISFDB3). It has already a custom filter to exclude unwanted tags (the ISFDB provides a lot!).

If there are others here who want such a functionality, I could (after requirements analysis here in the forum) write a suitable plugin.
