title: Tiddlers

Tiddlers are the smallest unit of information in TiddlyWiki. They can be structured with [[links|TiddlerLinks]] and tags.

Internally, tiddlers are an immutable dictionary of name:value pairs called fields. The only field that is required is the `title` field, but useful tiddlers also have a `text` field, and some or all of the standard fields listed below:

* `title` - The unique title of the tiddler
* `modified` - The date of the last modification to the tiddler
* `modifier` - The name of the last person to modify the tiddler
* `created` - The date the tiddler was created
* `creator` - The name of the person who created the tiddler
* `tags` - A list of tags applied to the tiddler
* `type` - The ContentType that should used to interpret the content of the tiddler
