Metadata describes a page or another object. An attribute is one named field, such as a task’s done value or a page’s status.

SilverBullet supplies fields such as page names and modification times. You can add your own:

• Frontmatter sets page attributes in a YAML block at the beginning of the page.
• Inline attributes attach values to a task, list item or paragraph.
• Hashtags classify content. Tag explains their scope and indexed fields.

For a worked example, follow Guide/Add Structure and Query. For the fields SilverBullet supplies, start at Object and the individual tag references.
