Fields

3rd May 2021 at 8:51pm

Tiddlers are made up of fields. Each field has a name, which describes what information it stores, and a value, which contains the actual information. For example, the field named description might have a value of This tiddler discusses fields in TiddlyWiki.

The most important fields of every tiddler are the title and the text; the title is how you reference the tiddler from elsewhere in the wiki, while the text contains the actual content, written in a markup language called wikitext (more on that in the next section). Other built-in fields include the tiddler's tags (more on those in a few moments too), the user who last edited the tiddler, and the times the tiddler was created and last modified.

In addition to the built-in fields, you can add your own fields to any tiddler on the fly, should you wish to. For instance, you might add fields to a tiddler containing meeting notes to define what time the meeting happened and who attended. Storing this information in separate fields, rather than directly within the text of the tiddler, lets you retrieve specifically that information for use in another part of the wiki, or search and filter based on it.

Here are this tiddler's fields as an example (not including the text field, since that would cause the example to include itself!). Field names are in the left column, while their values are in the right column. Don't worry if you don't understand the meaning or significance of all these fields yet.
