Metadata is data about data. There are a few entities you can add meta data to:
Metadata is data about data. Most [[Objects]] have a set of default attributes that can be augmented in a few additional ways:
* **page**: Pages have a default set of meta data built-in, but this can be expanded through mechanisms described below. The available metadata for a page is:
* `name`: The full name of the page
* `lastModified`: a timestamp (in ms since 1970-01-01) of when the page was last modified
* `perm`: either `ro` (read-only) or `rw`: this determines whether the editor opens in read-write or read-only mode.
* `contentType`: for pages always `text/markdown`
* `size`: the size of the file in bytes
* `tags`: A list of tags used in the top-level of the page (if any)
* **item**: Every list item appearing in a numbered, or unordered list is indexed and contains the following default set of metadata:
* `name`: The full content of the item minus attributes (see later)
* `page`: The page the item appears in
* `pos`: The offset (number of characters from the beginning of the page) where the item starts
* `tags`: A list of tags used in the item (if any)
* **task**: Every task defined in the space using the `* [ ] Task name` syntax
* `name`: The full task name/description
* `done`: Whether the task has been marked as done
* `page`: The page where the task appears
* `pos`: The offset (number of characters from the beginning of the page) where the item starts
* `tags`: A list of tags used in the task (if any)
* **tag**: Every tag used in the space
* `name`: The name of the tag (without `#`)
* `freq`: The frequency of the use of the tag
In addition, this metadata can be augmented in a few additional ways:
* [[Tags]]: adds to the `tags` attribute
* [[Tags]]: to tag the object (and add to the `tags` attribute directly)
* [[Frontmatter]]: at the top of pages, a [[YAML]] encoded block can be used to define additional attributes to a page
* [[Attributes]]
* [[Attributes]] syntax
