[Feature Request]: An option to display inherited tags as if they had explicitly been added

Description

Current tag inheritance system is confusing and does not make sense in some use cases

Let's say you've created category tags Author, Character and Copyright.
Now you are trying to add a book.
Create tag "Sir Arthur Conan Doyle" (Parent tags: Author)
Create tag "Sherlock Holmes (Book Series)" (Parent tags: Copyright, Sir Arthur Conan Doyle)
Create tag "Dr Watson" (Parent tags: Character, Sherlock Holmes (Book Series))

Now, since "Dr Watson tag" inherits all others, you should be able to add just this one tag and be good to go? Wrong.

Fig.1. Huh, that ain't right

So you add the rest of tags.

Fig.2. Now that makes even less sense

And yeah, this is still wrong.

Because tags inherit properties of their parent tags and not parent tags itself, you cannot:

• properly use tags with parent tags from multiple categories
• see parent tags after adding just children tags (despite the fact you can still search using parent tags)

Solution

So why not also add tag implications?

For example:
If:

• tag X implies tag Y
• tag Y implies tag Z

Then:

When adding tag X, automatically add tag Y, and, therefore, tag Z.
Even if tags are not parents to each other

Using example from above:

Create tag "Sir Arthur Conan Doyle" (Parent tags: Author)
Create tag "Sherlock Holmes (Book Series)" (Parent tags: Copyright) (Implies: Sir Arthur Conan Doyle)
Create tag "Dr Watson" (Parent tags: Character) (Implies: Sherlock Holmes (Book Series))

adding just Dr Watson should yield

which would solve both the issue of incorrect multiple categories (since tags are no longer parents of each other)
and of viewing/searching (now all tags are visible and are still "by parent-tag" searchable since implied tags will always be present when implying tag is also present)

Alternatives

No response

[Computerdores]

Just to be clear: Adding "Dr Watson" will make the entry show up in searches for "Dr Watson", "Sir Arthur Conan Doyle" or "Sherlock Holmes (book series)", this is already the case.

Considering that, you are only looking for an option to display inherited tags as if they had explicitly been added, right?

[A-Sverdrup]

1. Yes, i am looking for an option to display inherited tags as explicitly added,
   but also
2. somehow prevent tags from inheriting multiple categories.

[Computerdores]

Which categories are displayed is still a work in progress atm because of issues like this, so this will definitely be improved.

There has also been the idea to only put a tag into the first category up the tree (so "Dr Watson" would only be in the Character Category), but there hasn't been a consensus on this yet.

[A-Sverdrup]

Understood.

And what about "an option to display inherited tags as if they had explicitly been added"?

[A-Sverdrup]

As of multiple category inheritance (again)

Would'nt be an easier solution to add a separate inheritance list for just the categories, plain or nested (#922)? Although this may cause its own issues if a category inherits a non-category tag.

And what about "an option to display inherited tags as if they had explicitly been added"?

Hasn't been an idea so far, but I think it is a good thing to have as an option.
If want, you can edit this issue to specifically ask for that (specifically the title would help).
