Help:Type Keyword

The datatype Keyword is used to strings of restricted length.CiteRef::gh:smw:3020 It is similar to, but has the following differences:


 * Keywords are restricted in length (150 for ASCII, 85 for UTF-8)
 * they are normalized (lowercased, removed diacritics)
 * the original annotation value is kept but during a query request the normalized value is used to match the broadest possible result set which means whether you use,  , or   the normalized version will always match the keyword
 * Keywords allow to add a formatter rules (see below) which will self link any keyword to a link_to target to have immediate access to entities that have the same normalized keyword annotated

Formatter rule
Any keyword typed property can have its own formatter rule assigned which defines how links should be generated. For details, see Help:Rule. If the property has no formatter rule then it just displays the annotated value.
