Property from Backlink

Automatically add or remove a frontmatter property on every note that links to a given note, using that note's name as the value.

What it does

This plugin gives you two command, built around the same idea: keeping a frontmatter property in sync with a note's backlink.

• "Tag backlinks of this note with property" - adds the property to every note linking to the current note

• "Remove property added by this note from backlinks" - removes the property to every note linking to the current note

Both work the same way:

• Open the note you want to use as the "source" (e.g. a MOC note called Projects)
• Run the command
• Every note that links to it is updated

Tagging backlinks

The plugin never overwrites data, it only adds to it:

• No existing property → the property is created with the source note's name as its value.
• Existing property with the same value already → nothing changes.
• Existing property with a different single value → the property becomes a list containing both the old and the new value.
• Existing property already a list → the new value is appended, unless it's already present. Running the command multiple times on the same note is always safe (idempotent) — it will never create duplicate entries.

Removing the property

• Property holds only that value → the property itself is removed from the note.
• Property is a list containing that value among others → only that value is removed; the rest of the list is left untouched. If only one value remains, the property becomes a plain value again instead of a single-item list.
• Property doesn't contain that value → nothing changes. Like tagging, this is safe to run multiple times — running it again on a note that's already clean does nothing.

Settings

• Property name — the frontmatter property used to store the source note's name. Defaults to moc. Change it to category, hub, or anything that fits your vault's conventions.
