Can I have custom taxonomy frontmatter path?


In short; I have something like this:

  owner: Me
  tags: [ "cool" ]

Is there a way to get owners (like authors) and tags as custom taxonomies?
I have custom layouts for these pages; so if copying front matter keys in templates is possible, that could be a solution! But I’m not sure if it is allowed.

I’m not sure that I understand the question. If you want a custom taxonomy you must:

1) Define it in your site configuration

  owner: owners
  tag: tags

2) Set values at top level of your front matter

title: My Title
  - john
  - tom
  - foo
  - bar

I need owners to be nested inside something else (preferably arbitrarily) if possible.

That’s the only way to apply terms to a given taxonomy in front matter.
