A **[[Property]]** is an explicit piece of data that is both *about* the page and *on* the page. They help describe pages in a clear, concise, and standardised manner. They are a core piece of the [[System]]. ^about Note that depending on the [[Pub Wrap|style settings]] for an individual page: some, all, or none of its properties may be visible. As this [[System]] is built using [[Obsidian|Obsidian]], the underlying concept and principles are represented by [Obsidian Properties](https://help.obsidian.md/Editing+and+formatting/Properties). They are metadata for all intents and purposes. They are stored as frontmatter YAML in source files.
