How to easily unify YAML

Help
1

Is it necessary, that in yaml front matter aliases: and tags: have to be number one and two?

aliases:
tags: 
some: 
thing: 
else:

Are there other solutions available to manipulate one vaults YAML front matter than the great linter plugin? My goal is to folderwise and recursive clean my YAML front matter to unify them. (I’m trying to avoid having to do this manually.)

The order is not pre-defined by any convention. Doesn’t matter. You can do it .e.g. with Notepad++ with regular expression search and replace.
There is a Python script someone wrote somewhere (search: YAML Python on forum) that lets you organize your frontmatter; personally, I never tried it.
