Edit Property: Property:Property defaultValue

default value - Specifies a default value for this field. For date-related fields, default=now will set the value to the current date and possibly time. For text fields, default=current user will set the value to the username of the user adding this page. For the checkbox input type, default=yes will check the checkbox by default. (The 'checkboxes' input type, on the other hand, like the 'listbox' type, requires specifying the actual values, like default=Value A, Value C.) You can also include templates, parser functions, and magic words within the 'default=' value. see http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag (default)
