Tiddlers can have attributes known as custom fields (also known as extended fields). A field can be anything that describes or extends the data in the tiddler. For instance fields describing geo data can be associated with a tiddler.
This tiddler has a custom field "color" which could potentially be used to set a background colour, a tiddler title or express a favourite colour.
You can view fields on a tiddler by clicking on the more button in your toolbar and selecting the fields option or via the TiddlySpace API. For example see the txt serialization for this tiddler.
By default it is not possible to edit custom fields with a basic TiddlySpace. You will need to include a space that exposes the editing of them (for instance the first-class-fields space).
