Semantic search

There 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.

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.
