basicJots primarily live in the Frontmatter/YAML of the note, and consist of two parts: The Key which defines what kind of information it is, and the value which provides the detail of that piece of information.
In Obsidian, a basicJot is otherwise known as a ‘Property’ if it lives in the Frontmatter/YAML of the note, or an ‘Inline Field’ if it lives in the body of the note.
