Properties

Property allowedValuesThere are two ways to specified allowed Values:
  1. https://semantic-mediawiki.org/wiki/Help:Special_property_Allows_value.
    Use Property:Allows_value to see which values are allowed for certain properties
  2. 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/TextallowedValuesallowedValuesfalsefalse
Property defaultValuedefault 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/CodedefaultValuedefaultfalsefalse

  • 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.
