FrontMatter or MetaData / Inline for Keys

So I need some helps from people who are already using Obsidian and plugins for a longer time.

What is the best approach to store custom keys: FrontMatter or MetaData / Inline?

Just found out that duplicating the Keys in FrontMatter and MetaData / Inline not really works when you want to use the Dataview plugin.

Any insights?

It works… The problem is: you have two values (an array). For that you can’t use WHERE field = "value", because “=” means equals. You need to use contains().

what would the syntax be?

WHERE  Vault.contains("Privat")


Dataview: Every row during operation 'where' failed with an error; first 3:

                - Cannot call type 'array' as a function
- Cannot call type 'null' as a function
- Cannot call type 'null' as a function

see answer in other post: Dataview with keys from frontmatter not working - #6 by mnvwvnm

ok, I stand corrected that this doesn’t work with dataview.

But how do other people use the FrontMatter and MetaData / Inline Keys?

Both, only FrontMatter, only MetaData / Inline, depends?

I think it’s a matter of personal preference.

For myself, I usually prefer using inline DataView fields (e.g. Field:: Value) over YAML because I consider the fields to be part of the content of the page, and I want them to be visible when I look at the page in reader mode.


I agree with @Craig - there’s not a “best way”.

There’re cases where the best option is the yaml field, others the inline field.

An example: if you use in frontmatter aliases: other title Obsidian automatically recognized this field as your note alias. As metadata, this becomes a value in the implicit field file.aliases (a default array). If you add this field as inline field - aliases:: other title- this is just a normal custom field with the key-name aliases, not a really alias to your note!

Another one: if you use an inline file as key:: [[File A]], because the link is in your note content, [[File A]] becomes also an outgoing link, recognized in “outgoing links” pane and in graphs. If instead you use an yaml frontmatter field - key: "[[File A]]" - this link doesn’t account as outlink neither shows in graphs (also, it doesn’t auto-update the link if you change the file name).

These are some examples… We can’t list all the nuances. You need to explore and understand the differences.

thanks for the starting information, so much to learn :grinning:
I think I will for sure try to separate the more “immutable” data into yaml and the more dynamic (and in your face) data inline.
But I agree you need to learn and adopt it for yourself.
