Property allowedValues	allowedValues	allowedValues	Types/Text	13		false	false		50	false				There are two ways to specified allowed Values: https://semantic-mediawiki.org/wiki/Help:Special_property_Allows_value. Use Property:Allows_value to see which values are allowed for certain properties http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag values=possible values - Specifies a set of either possible values or autocompletion values (depending on the input type) that this field can have, overriding whatever set of values may have been set from the Semantic MediaWiki property. This set of values is separated by commas by default, but the delimiter can be modified using the delimiter= parameter. If you specify any values method number 2 will be used here which might override any allowed Values specified with method number 1.			false		Property
Property defaultValue	defaultValue	default	Types/Text	11		false	false		80	false				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)		false	false	false	Property

If a field corresponds to an SMW property or Cargo field, the form will usually have the correct input type by default; otherwise the default is text. If the corresponding SMW property, or Cargo field, cannot be automatically determined, you can use the parameter 'property', or the parameters 'cargo table' and 'cargo field', to manually specify it (see below). The allowed set of input types is different for every semantic property type; see below for the full list of options. http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#Allowed_input_types_for_data_types http://www.mediawiki.org/wiki/Extension:Semantic_Forms_Inputs		false	false	false	Property

Property mandatory	mandatory	mandatory	Types/Boolean	7		false	false		4	false				Specifies that this field must be filled in by the user. Note: mandatory should not be used in conjunction with hidden.

(To get values from the main namespace, use 'Main' for the namespace name, or just leave it blank.) values from url=URL identifier - Used only for autocompletion. Specifies that autocompletion should be based on the values retrieved from an outside URL; see Autocompleting on outside values for how to do this. values from external data=variable name - Used for autocompletion. You need to have theExternal Data extension installed to be able to use this parameter. It specifies that autocompletion should be based on the data retrieved from an outside source. A large number of data sources are supported, including web APIs, regular wiki pages, files on the local server, databases and LDAP directories. See Autocompletion using External Data.		false	false	false	Property
