Properties

	documentation	type	name	label	allowedValues	mandatory	uploadable
Property allowedValues	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.	Types/Text	allowedValues	allowedValues		false	false
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)	Types/Code	defaultValue	default		false	false
Property documentation	The documentation for a property	Types/Text	documentation	documentation		false	false
Property externalFormatterURI	see https://www.semantic-mediawiki.org/wiki/Help:Special_property_External_formatter_URI When using this property the type of the property should be set to https://www.semantic-mediawiki.org/wiki/Help:Type_External_identifier automatically by the generator	Types/Text	externalFormatterURI	external formatter URI		false	false
Property index	A positive number that specifies at which position of a Topic the given property should show. The first property to show has the index 1 each following property has an index that is +1 of the previous.	Types/Number	index	index		false	false
Property inputType	see http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag input type - Specifies the type of input this field will have in the form. 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	Types/Text	inputType	inputType	text, combobox, dropdown, textarea, tree, datetime, datepicker, timepicker, datetimepicker, menuselect,two listboxes, datecheck, regexp, radiobutton, googlemaps	false	false

Property label	The label to be shown when in a form	Types/Text	label	label		false	false
Property mandatory	Specifies that this field must be filled in by the user. Note: mandatory should not be used in conjunction with hidden. Use of both in any field will cause the mandatory check on any field to fail when the form is saved. see http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag	Types/Boolean	mandatory	mandatory		false	false
Property name	The name of the property	Types/Text	name	name		true	false
Property namespace	namespace prefix	Types/Text	namespace	namespace		false	false
Property nullable	should nullvalues be allowed and value set to NULL when empty?	Types/Boolean	nullable	allow nulls?		false	false
Property primaryKey	is this property a primary key of it's topic?	Types/Boolean	primaryKey	primary key		false	false
Property scope	The scope of the property	Types/Text	scope	scope	Root,Override,Global	true	false
Property showInGrid	I am true if this property is displayed in the default list of properties for my topic as a column	Types/Boolean	showInGrid	showInGrid		false	false
Property size	the display size of the field for the property	Types/Number	size	size		false	false
Property sortPos	If none empty >0 this is the position in the sort clause of this property. This is used when displaying list of the topic as the default sort order and it is used for selecting topics . E.g. Sortpos 1 for attribute lastname and sortpos 2 for attribute firstname leads to sort by lastname,firstname	Types/Number	sortPos	sortPos		false	false
Property topic	topic	Types/Page	topic	topic
Property type	The type of a Property	Types/Page	type	type		false	false
Property uploadable	Specifies that a link should be placed next to this field, that opens a popup window to let the user upload a file; see 'Uploading files', below. See https://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag https://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#Uploading_files The type of the target property needs to be Page for this to work	Types/Boolean	uploadable	uploadable		false	false
Property values from	Specifies where to get the possible values to be displayed in a form from see http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms#.27field.27_tag values from property=property name - Similar to values=, but gets its values from the the set of all values that a certain SMW property points to. values from category=category name - Similar to values=, but gets its values from the names of all pages belonging to a specific category. values from concept=concept name - Similar to values=, but gets its values from the names of all pages belonging to a specific concept. values from namespace=namespace name - Similar to values=, but gets its values from the names of all pages belonging to a specific namespace. (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.
