Metadata

pkm reads YAML frontmatter at the top of Markdown files.

Common Fields

Field	Type	Purpose
`title`	string	Human note title
`aliases`	list	Alternate names for link resolution
`tags`	list	Filtering, search, and heat scoring
`type`	string	Registered note type
`created`	date	Creation date
`modified`	date	Last modified date
`related`	list	Manual related links

Any top-level field can be used as type-specific metadata.

Custom fields are indexed into SQLite metadata for future querying and tooling.

pkm still indexes plain Markdown notes. The title is derived from the first H1 or filename stem.
