# Field

Fields are the building blocks of metadata stored in [entries](/doc/Entry.md). Fields have several base types for representing different kinds of information, including:

#### `text_line`
  - A string of text, displayed as a single line.
    - e.g: Title, Author, Artist, URL, etc.
#### `text_box`
  - A long string of text displayed as a box of text.
    - e.g: Description, Notes, etc.
#### `tag_box`
  - A box of [tags](/doc/Tag.md) defined and added by the user.
  - Multiple tag boxes can be used to separate classifications of tags.
    - e.g: Content Tags, Meta Tags, etc.
#### `datetime` [WIP]
  - A date and time value.
    - e.g: Date Created, Date Modified, Date Taken, etc.
#### `checkbox` [WIP]
  - A simple two-state checkbox.
  - Can be associated with a tag for quick organization.
    - e.g: Archive, Favorite, etc.
#### `collation` [obsolete]
  - Previously used for associating files to be used in a [collation](/doc/Macro.md/#create-collage), will be removed in favor of a more flexible feature in future updates.
